F. FISH
Sections II-C and II-D contain additional fish multivariate technique comparisons and
conclusions of the Mod Alt L creeks study. Section II-C considers juvenile fish within the context
of the forage base of the creeks and II-D considers managed fish over the study years. Section
G of Appendix A contains a history of fish collections and a description of methods. Water quality
data collected by CZR and analyzed by ECU are presented in Appendix E. Appendix H contains
raw fisheries data and the in -situ hydrographic data collected before each sample in 2021 for all
sampled creeks. Note that the ECU water quality samples are taken at various distances
upstream from where fish are trawled/fyke-netted and no ECU water quality samples are collected
in Muddy Creek.
1.0 Results and Discussion
The cluster analysis on similarity based on species richness and total abundance
for both trawl and fyke net creeks revealed 13 distinct groups among all the sampled creeks
across both analyses which are discussed in Section II-D. When appropriate, additional cluster
analysis and comparisons of each creek for all species and/or comparisons of particular species
within specific creeks was performed, and if necessary, those results were compared to control
creeks. Extra analyses were also performed to determine other differences or similarities among
the creeks that were less evident when all data for all creeks were used. Colored lines on the
cluster dendrograms represent non -significant structure among factors (e.g., years, creeks) at the
5 percent level (p = 0.05). Figures III-F1 through F16 display the significantly different multivariate
clusters for years within each creek and catch -per -unit -effort (CPUE) comparisons for various
species in various creeks. Table III-F1 lists total abundance and species richness (fish community
structure) for each creek across all years of the study. The results section on each creek below
is divided into two parts: a) creeks with pre- and/or post -Mod Alt L data and b) control creeks.
a. Pre -Mod Alt L Creeks
i. Broomfield Swamp Creek
The 2021 trawls for Broomfield Swamp Creek represented the third
year of fish collections and the third pre -Mod Alt L year. Nineteen (19) different species have
been captured over the three collection years (Table III-F2). In all three sample years, 11 species
were captured in Broomfield Swamp Creek with the number and percent of predominately
freshwater fishes gradually increasing through the sample years (Table III-F2). Total abundance
for Broomfield Swamp Creek was the lowest of all creeks in 2020 (142 individuals) and 2021 (136
individuals); the second and third lowest years ever recorded behind only Jacks 2016 (119) (Table
III-F1).
Spot, bluegill (Lepomis macrochirus), and Atlantic croaker represented the highest CPUEs within
Broomfield Swamp Creek in 2021 (Table III-F2). Atlantic croaker accounted for the highest CPUE
in 2021 and bay anchovy, a predominant species in 2019 and 2020, had a relatively low CPUE.
Three managed species were captured over the three years while two of those were captured in
every sample year (Atlantic croaker, and spot) and 10 of 19 total species captured were
freshwater species. These freshwater species comprised of 255 individuals; however, yellow
bullhead (Ameiurus natalis) caught only in 2019, accounted for 158 of those (Table III-F2).
III-F-1

b. Post -Mod Alt L Creeks
i. Jacks Creek
The 2021 trawls for Jacks Creek represented the 18th year of fish
collections and the seventh post -Mod Alt L year. Eleven years comprise pre -Mod Alt L (1999-
2005 and 2011-2014) and 2015-2021 comprise post -Mod Alt L. Community structure
comparisons indicate that species richness for Jacks Creek ranged from six in 2017 to 20 in 1999,
with a mean of 14 species over the 18 years (Table III-F1). The six species captured in Jacks
Creek in 2017 equaled Muddy Creek in 2007, Tooley Creek in 2016, and both Tooley and Long
creeks in 2017 and 2021 for the lowest number of species captured across all creeks/years. Total
abundance for Jacks Creek was lowest in 2016 (119 individuals) and highest in 2003 (6,638
individuals). Total abundance in both 2016 and 2017 (239 individuals) for Jacks Creek were the
lowest and sixth lowest number of individuals captured across all creeks/years, respectively;
however, total abundance in 2003 was the third highest across all trawl creeks/years behind only
2003 at Muddy Creek and 2010 at Tooley Creek (Table III-F1).
Multivariate cluster analysis of annual fish species composition and
abundance within Jacks Creek by a similarity profile test (SIMPROF) revealed some differences
of statistical significance between years (Figure III-F1). Cluster A consisted of post -Mod Alt L
years 2016-2017 and B again comprised only pre -Mod Alt L 1999, while both C and D each
contained five pre -Mod Alt L years (with both early and more recent years in each) with one post -
Mod Alt L year in C and four in D. Comparison of interannual variability between all four clusters
by similarity percentages (SIMPER) revealed 56 percent similarity between clusters C and D, 54
percent similarity between B and D, 35 percent similarity between A and C, 52 percent similarity
between B and C, 48 percent similarity between A and D, and 32 percent similarity between A
and B. Clusters A (2016-2017) and B (1999) contained the three of the six lowest total CPUEs
for Jacks Creek across all years with differences between the two clusters driven predominantly
by CPUE of rainwater killifish, spot, and pumpkinseed. Cluster C formed the third cluster with a
combination of both early and later years (2001-2002, 2011-2013, and 2018) with higher CPUE
of both pinfish and rainwater killifish than D; additionally, C had lower CPUE of both Atlantic
croaker and Atlantic menhaden. Cluster D primarily consisted of both early years (2000, 2003-
2005) and later years (2014, 2015, 2019, 2020 and 2021) all of which contained similar CPUE for
Atlantic menhaden and bay anchovy while most of the cluster contained similar CPUE for spot
and Atlantic croaker, in addition to low CPUE for both pinfish and rainwater killifish. (Figure HI-
FI and Table III-F3). Total CPUE for 2016 was nearly 18 times less and total CPUE for 2017 was
almost 9 times less than the long term average of all other years in Jacks Creek. Those two years
each had CPUEs less than 20 while the long term average CPUE for 1999-2021 collection years
was 168.0. 2021 had a CPUE of 58.44 that contributed to the post -Mod Alt L CPUE of 87.78 which
was considerably lower than pre -Mod Alt L CPUE (220.38) (Table III-F3). To date, 16 species
were caught only in pre -Mod Alt L years; 11 were captured only once or twice, five were caught
only in the early years (1999-2005), and one, summer flounder, was caught in eight of the 11 pre -
years but not since (Table III-F3). Three species were caught only post -Mod Alt (in 2020), Atlantic
needlefish (Strongylura marina), gizzard shad (Dorosoma cepedianum), and northern pipefish
(Syngathus fuscus) none of which were among the top five dominants (Table III-F3).
Spot dominated fish assemblages within Jacks Creek in all years,
except 2005, 2019 and 2021 when Atlantic croaker represented the highest total CPUE (Table
III-F3). During 1999-2005, Jacks Creek fish predominantly consisted of spot, Atlantic croaker,
Atlantic menhaden, and bay anchovy, with a large influx of pinfish captured in 2002. By 2011,
Atlantic croaker were replaced by pinfish until 2013, and in 2012 and 2013, neither Atlantic
III-F-2

menhaden nor bay anchovy remained one of the top four most abundant species as in earlier
years; however, both reemerged as prominent species again in 2014-2020, with the exception of
no Atlantic menhaden captured in 2017 and three in 2019. Conversely, not caught at all from
1999-2005, the CPUE of eastern mudminnow (Umbra pygmaea) increased in 2011 through 2013
to one of the most abundant species before it declined back to zero with no individuals captured
in 2014-2021. Three species were caught in Jacks Creek every year of the study: Atlantic croaker,
bay anchovy, and spot (Table III-F3). Nine managed fish species were captured in Jacks Creek
over the 18 years and 11 of 37 total species captured were freshwater species; however, 1999
represented the most freshwater species captured with seven while 13 of the 18 years ranged
between zero and two (Table III-F3). While two other freshwater species were among the top five
dominants in an earlier year, for the first time, CPUE for bluegill, another freshwater species, was
among the top five dominants in 2020; however, the pre- Mod Alt L total freshwater species (11)
was almost three times higher than the post -Mod Alt L total (4) (Table III-F3).
Comparison of interannual variability between pre- and post -Mod
Alt L fish assemblages within Jacks Creek by similarity percentages (SIMPER) revealed 53
percent similarity, with differences between pre- and post -Mod Alt L years driven by CPUE of
spot, pinfish, and Atlantic croaker. Total CPUE for Jacks Creek has increased/decreased
throughout most years with no definitive trend; however, as stated earlier, the five lowest years in
terms of CPUE have occurred post -Mod Alt L which contributed to a lower total CPUE than pre -
Mod Alt L. Although total post -Mod Alt L CPUE for Jacks Creek has trended upward in most
recent post -Mod Alt L years, comparison of interannual variability between pre- and post -Mod Alt
L fish assemblages within Jacks Creek by ANOSIM detected spatial differences of statistical
significance [Global R = 0.287; p = 0.010] due to generally lower CPUEs in most earlier post -Mod
Alt L years. Spot catch highly influenced total CPUE of all species for each year in Jacks Creek
and represented over 50 percent of total catch in 10 of the 11 pre -Mod Alt L sample years prior
to a lesser influence on total CPUE in the seven post -Mod Alt L years. In addition to spot, CPUE
of pinfish also accounted for the bulk of the difference between pre- and post -Mod Alt L sample
years in Jacks Creek as no pinfish were captured in four of the seven post -Mod Alt L years. The
lower total CPUE in six of the seven combined post -Mod Alt L years and overall decline in
dominant species, like spot and pinfish, at Jacks Creek in six of the seven post -Mod Alt L years
set the post -Mod Alt years apart from pre -Mod Alt L years. Of note and discussed in more detail
in the section on control creeks below, along with 2011, overall CPUE in Muddy Creek in 1999,
2016, 2017 and 2021 was also less than 100. Spot CPUE in Muddy from 2000-2010 also declined
in later years; CPUE was three digits in that early period while only two digits since 2011 (see
Table III-F14 for Muddy CPUE).
As indicated by statistically significant differences in interannual
variability between pre- and post -Mod Alt L fish assemblages in Jacks Creek, there were also
statistically significant differences among CPUE for a number of individual species between pre -
and post -Mod Alt L years. Of the nine managed species captured in Jacks Creek, spot, summer
flounder and American eel displayed significant differences among CPUE between pre- and post -
Mod Alt L years by means of t-test, with lower CPUE in the combined post -Mod Alt L years than
the combined pre -Mod Alt L years for spot [small(n) = 91, big(n) = 144; T = 7,839.0; p = <0.001],
for summer flounder [small(n) = 91, big(n) = 144; T = 9,253.0; p = <0.001], and for American eel
[small(n) = 91, big(n) = 144; T = 10,057.0; p = 0.021] (Figure III-F2). As with managed species,
CPUE for commonly captured species such as bay anchovy, pinfish, eastern mudminnow, and
rainwater killifish in combined post -Mod Alt L years was significantly lower than combined pre -
Mod Alt L years for bay anchovy [small(n) = 91, big(n) = 144; T = 9,508.0; p = 0.011], for pinfish
[small(n) = 91, big(n) = 144; T = 8,380.0; p = <0.001], for eastern mudminnow [small(n) = 91,
III-F-3

big(n) = 144; T = 9,873.5; p = <0.001], and for rainwater killifish [small(n) = 91, big(n) = 144; T =
9,538.0; p = 0.003] (Figure III-F2).
Jacks Creek's pre- and post -Mod Alt L years were used to compare
variability among fish species composition and abundance for spot, summer flounder, American
eel, bay anchovy, pinfish, eastern mudminnow and rainwater killifish in Muddy Creek (control).
Muddy Creek exhibited similar trends in CPUE and significance pre- to post -Mod Alt L years as
Jacks Creek for all species except American eel. Available Jacks Creek pre- and post -Mod Alt L
years were also used to compare the same species in Little Creek (2011-2014 for pre -Mod Alt L
and 2015-2021 for post -Mod Alt L). Little Creek exhibited similar trends for all species except bay
anchovy and spot did not display significant differences between limited pre -Mod Alt L years and
combined post -mod Alt L years. Total CPUE was also compared between matching Jacks years
(2011-2021) and Little years (2011-2021) to compare variability for total abundances, the t-test
did not display a statistical difference between the two creeks.
ii. Jacobs Creek
The 2021 trawls for Jacobs Creek represented the 11 th year of fish
collections. The first three years comprise pre -Mod Alt L (2011-2013) and 2014-2021 comprise
post -Mod Alt L. Community structure comparisons for Jacobs Creek indicate that species
richness ranged from 10 in 2019 and 2021, to 19 in both 2015 and 2018 (Table III-F1). Total
abundance for Jacobs Creek ranged from 406 individuals in 2016 to 5,119 in 2020; total
abundance in 2020 for Jacobs Creek was the fifth largest number of individuals captured across
all trawl creeks for 2011 through 2021 behind only PA2 (2014, 2020 and 2021) and Duck Creek
(2020). Mean species richness (16) in Jacobs Creek was the second highest behind PA2 and
mean abundance (2,351) was the fifth highest behind Muddy, Tooley, PA2, and Porter among all
trawled creeks from 2011-2021 (Table III-F1).
Multivariate cluster analysis of annual fish species composition and
abundance within Jacobs Creek by a similarity profile test (SIMPROF) revealed a statistical
significance between years (Figure III-F3). Sample years in Jacobs Creek formed three clusters:
Cluster A contained just post -Mod Alt L 2016, cluster B consisted of post -Mod Alt L years 2017,
2019 and 2021, and C comprised all pre -Mod Alt L years (2011-2013) and post -Mod Alt L years
2014-2015, 2018, and 2020. Comparison of interannual variability between clusters A, B and C
by similarity percentages (SIMPER) revealed 44 percent similarity between A and C, 65 percent
between A and B, and 50 percent between B and C with differences driven predominantly by low
CPUE of pinfish, spot, and rainwater killifish in the three post -Mod Alt L years in B; post -Mod Alt
L 2019 and 2021 saw zero captures of pinfish and no capture of rainwater killifish in 2019; post -
Mod Alt L 2016 had the lowest spot CPUE for Jacobs Creek across all years alongside zero
pinfish captures causing it to group alone in A (Figure III-F3 and Table III-F4).
Fish assemblages within Jacobs Creek consisted of spot, Atlantic
croaker, bay anchovy, and pinfish among the top five dominants captured, with fluctuations in
catches among rainwater killifish, Atlantic menhaden, and eastern mudminnow each year;
however, after a high in 2012, the eastern mudminnow declined in 2013 with none captured post -
Mod Alt L (2014-2021) (Table III-F4). Five species have been captured every year of the study,
Atlantic croaker, bay anchovy, spot, hogchoker (Trinectes maculatus), and inland silverside;
however, the last two species were among the five dominants only once (Table III-F4). Nine
managed fish species were captured in Jacobs Creek over the eleven years; six of them were
never among the top five dominants, although four were present in 10 or 11 of the years (Table
III-F-4

III-F4). Eight of 34 total species captured were freshwater species and comprised 620 individuals
(eastern mudminnow alone accounted for 433); two freshwater species were captured pre -Mod
Alt L while seven have been captured post -Mod Alt L (Table III-F4).
Comparison of interannual variability between pre- and post -Mod
Alt L annual fish assemblages within Jacobs Creek by similarity percentages (SIMPER) revealed
53 percent similarity, with differences between pre- and post -Mod Alt L years driven by CPUE of
pinfish, eastern mudminnow, spot, and Atlantic croaker. Although total CPUE in post -Mod Alt L
2016 and 2017 were more than two times less than total CPUE of any other year (Table III-F4)
comparison of interannual variability between pre- and post -Mod Alt L fish assemblages within
Jacobs Creek by ANOSIM detected no spatial differences of statistical significance.
There were statistically significant differences among CPUE for a
number of individual species between pre- and post -Mod Alt L years. Of the nine managed
species captured in Jacobs Creek, American eel, summer flounder, and Atlantic croaker displayed
significant differences in CPUE between pre- and post -Mod Alt L years by means of t-test, with
lower CPUE in the combined post -Mod Alt L years than the combined pre -Mod Alt L years for
summer flounder [small(n) = 39, big(n) = 104; T = 3,846.0; p = <0.001] and American eel [small(n)
= 39, big(n) = 104; T = 3,214.5; p = 0.003] and higher CPUE in post -Mod Alt L years for Atlantic
croaker [small(n) = 39, big(n) = 104; T = 1,786.0; p = <0.001]. The CPUE for commonly captured
species such as pinfish, eastern mudminnow and silver perch in combined post -Mod Alt L years
was also significantly lower than combined pre -Mod Alt L years for pinfish [small(n) = 39, big(n) =
104; T = 3,889.0; p = <0.001], for eastern mudminnow [small(n) = 39, big(n) = 104; T = 3,900.0;
p = <0.001] and for silver perch [small(n) = 39, big(n) = 104; T = 2,946.0; p = 0.029] and higher in
post -Mod Alt L years for bay anchovy [small(n) = 39, big(n) = 104; T = 2,320.5; p = 0.024] (Figure
III-F4).
Jacobs Creek's pre- and post -Mod Alt L years were used to
compare variability among fish species composition and abundance for Atlantic croaker,
American eel, summer flounder, pinfish, eastern mudminnow, silver perch and bay anchovy in
two nearby control creeks, PA2 (adjacent to Jacobs) and Long Creek (across South Creek from
Jacobs). Both PA2 and Long Creek exhibited similar trends in CPUE as Jacobs Creek for all
seven species; however, although CPUE of Atlantic croaker in PA2 and bay anchovy in PA2 and
Long was higher in combined post -Mod Alt L years none were statistically significant as in Jacobs
Creek.
Drinkwater Creek
The 2021 trawls for Drinkwater Creek represented the 11th year of
fish collections. The first two years comprise pre -Mod Alt L (2011-2012) and 2013-2021 comprise
post -Mod Alt L. Community structure comparisons for Drinkwater Creek indicate that species
richness was highest in 2011 (20) and reached a low of seven species in 2021; the 20 species
captured in 2011 was the second highest species richness among all creeks sampled in 2011
and the highest among all 2011 trawled creeks; and equaled both Jacks Creek in 1999 and PA2
in 2014 and 2020 for the highest species richness among all trawl creeks/years while the seven
species captured in 2021 was tied with nine other creek/years for second lowest abundance ever
recorded among trawled creeks (Table III-F1). Total abundance for Drinkwater Creek increased
the first three years then decreased each of the next three years to a low of 368 individuals
captured in 2016, then began a general upward trend through 2020 before reducing to a near
average total in 2021; 2016 total abundance was the second lowest across all creeks trawled in
III-F-5

2016 and was the sixth lowest across all trawl creeks/years. Mean species richness in Drinkwater
Creek (14) was tied for the third highest and mean abundance (1,653) was the fifth lowest among
all trawled creeks (Table III-F1).
Multivariate cluster analysis of annual fish species composition and
abundance within Drinkwater Creek by a similarity profile test (SIMPROF) revealed a statistical
significance between years (Figure III-F5). Sample years in Drinkwater Creek formed two
clusters: cluster A consisted of five post -Mod Alt L years (2013, 2015-2017, 2019 and 2021) and
B contained both pre -Mod Alt L years 2011 and 2012 and post -Mod Alt L years 2014, 2018, and
2020. Comparison of interannual variability between clusters A and B by similarity percentages
(SIMPER) revealed 55 percent similarity with differences driven predominantly by CPUE of
pinfish, spot, inland silverside, rainwater killifish, and Atlantic croaker. Dissimilarity between total
CPUE of clusters A and B was driven primarily by increased CPUE of Atlantic croaker and
decreased CPUE of both pinfish and inland silverside in the six post -Mod Alt L years in A (Figure
III-F5 and Table III-F5).
Fish assemblages within Drinkwater Creek predominantly
consisted of spot, bay anchovy, Atlantic croaker, pinfish, and Atlantic menhaden, while catches
of rainwater killifish and inland silverside fluctuated across years; naked goby (Gobiosoma bosci)
and hogchoker were also present almost every year but never as a top five dominant (Table III-
F5). Five species were captured every year and were also frequently among the top five
dominants (spot, bay anchovy, Atlantic croaker, and Atlantic menhaden); only spot was in the top
five all 11 years (Table III-F5). Ten managed fish species were captured in Drinkwater Creek over
the ten years and seven of 34 total species captured were freshwater species. These seven
species comprised 198 individuals; however, although the eastern mudminnow declined each
year with none captured in 2014-2021, eastern mudminnow alone accounted for 139 of the 198
(Table III-F5).
Comparison of interannual variability between pre- and post -Mod
Alt L annual fish assemblages within Drinkwater Creek by similarity percentages (SIMPER)
revealed 55 percent similarity, with differences between pre- and post -Mod Alt L years driven by
CPUE of pinfish, Atlantic croaker, and eastern mudminnow. Although total CPUE for Drinkwater
Creek increased in later post -Mod Alt L years to approximately average totals, post -Mod Alt L
years 2014-2017 accounted for the four lowest total CPUEs for Drinkwater Creek across all years
(Table III-F5); accordingly, comparison of interannual variability between pre- and post -Mod Alt L
fish assemblages within Drinkwater Creek by ANOSIM detected spatial differences of statistical
significance [Global R = 0.544; p = 0.018].
There were statistically significant differences among CPUE for a
number of individual species between pre- and post -Mod Alt L years. Of the 10 managed species
captured in Drinkwater Creek, Atlantic croaker displayed significantly higher combined CPUE in
post -Mod Alt L [small(n) = 26, big(n) = 117; T = 1,121.0; p = <0.001] and both American eel
[small(n) = 26, big(n) = 117; T = 1,875.5; p = 0. 002] and summer flounder [small(n) = 26, big(n)
= 117; T = 2,181.0; p = <0.001] displayed significantly lower CPUE in combined post -Mod Alt L
years than combined pre -Mod Alt L years by t-test. As with most managed species, CPUE for
commonly captured species such as pinfish, eastern mudminnow and naked goby in combined
post -Mod Alt L years was significantly lower than combined pre -Mod Alt L years for pinfish
[small(n) = 26, big(n) = 117; T = 2,994.5; p = <0.001], for eastern mudminnow [small(n) = 26,
big(n) = 117; T = 2,795.0; p = <0.001] and naked goby [small(n) = 26, big(n) = 117; T = 2,399.5;
p = <0.001] (Figure III-F6).
III-F-6

Drinkwater Creek's pre- and post -Mod Alt L years were used to
compare variability among fish species composition and abundance for Atlantic croaker,
American eel, summer flounder, pinfish, eastern mudminnow and naked goby in two nearby
control creeks, PA2 (adjacent to Drinkwater) and Long Creek (across South Creek from
Drinkwater). PA2 and Long Creek exhibited similar trends in CPUE as Drinkwater Creek for all
six species; however, although CPUE of American eel was also lower in post -Mod Alt L years in
Long it was not statistically significant nor was naked goby in PA2 as was the case in Drinkwater
Creek.
iv. Tooley Creek
The 2021 trawls for Tooley Creek represented the 15th year of fish
collections (1999-2001 and 2010-2021). Pre -Mod Alt L years consisted of 1999-2001 and 2010-
2011, and post -Mod Alt L year were comprised of 2012-2021. Community structure comparisons
for Tooley Creek indicate that species richness ranged from a low of six in 2016, 2017 and 2021
to 17 in both 1999 and 2013; 2016, 2017 and 2021 equaled Muddy Creek in 2007, both Jacks
Creek and Long Creek in 2017 and Long Creek in 2021 for the lowest species richness among
all creeks/years (Table III-F1). Total abundance for Tooley Creek ranged from 276 individuals in
1999 to 7,437 in 2010; 1999 abundance was the sixth lowest number of individuals captured
across all trawl creeks/years and the seventh lowest number of individuals captured across all
creeks/years. Conversely, 2010 abundance in Tooley Creek was the second highest number of
individuals captured across all trawl creeks/years (Table III-F1). Mean species richness (12)
across all trawl creek/years was third lowest behind SCUT1 and Porter (tied at 10), Broomfield
Swamp and Long creeks; mean abundance (2,485) across all trawl creek/years was third highest
behind Muddy Creek and PA2 (Table III-F1).
Multivariate cluster analysis of annual fish species composition and
abundance within Tooley Creek by a similarity profile test (SIMPROF) revealed slight variation of
statistical significance between years (Figure III-F7). Sample years in Tooley Creek formed three
clusters: cluster A consisted of 1999, B contained two pre -Mod Alt L years (2000 and 2010) and
six post -Mod Alt L years (2014-2021), and C contained two pre -Mod Alt L years (2001 and 2011)
and two post -Mod Alt L years (2012-2013). Comparison of interannual variability between all three
clusters by similarity percentages (SIMPER) revealed 54 percent similarity between B and C, 40
percent similarity between A and C, and 29 percent similarity between A and B. The single year
in cluster A (1999) had the lowest total CPUE for Tooley Creek across all years (at least two times
less than the total CPUE of any other years and more than 27 times less than the highest pre -
Mod Alt L total CPUE and more than 13 times less than the highest post -Mod Alt L total CPUE);
clusters B and C separated primarily due to dissimilarity in CPUE of pinfish, Atlantic croaker, spot,
and to a lesser extent, bay anchovy and Atlantic menhaden (Figure III-F7 and Table III-F6).
Spot accounted for a large portion of fish assemblages within
Tooley Creek every year but 2017 and influenced total catch in all years; in addition to spot, other
impactful fish included Atlantic croaker, bay anchovy, pinfish, and Atlantic menhaden. Seven
species were captured only in pre -Mod Alt L years while four were captured only post -Mod Alt L;
only one of these was ever among the top five dominants, crevalle jack in 2017 with just one
individual captured; however, as mentioned above, total CPUE in 2017 and species richness were
low that year (Table III-F6). Nine managed species have been captured in Tooley Creek over the
15 years sampled. Southern flounder was the only managed species to rank within the top five
CPUEs of any given year (2017 and 2020) (Table III-F6). Eight of 33 total species captured were
III-F-7

freshwater species and comprised 125 individuals; however, two species, eastern mosquitofish
(Gambusia holbrooki) (48 individuals) and pumpkinseed (49 individuals), accounted for 97 of the
125. The year with the most freshwater species was 1999 with five; all subsequent years
fluctuated between zero and two; pumpkinseed in 1999 was the only freshwater species ever
among the top five dominants and along with pinfish that year, had the lowest total CPUE of the
five (Table III-F6).
Comparison of interannual variability between pre- and post -Mod
Alt L fish assemblages within Tooley Creek by similarity percentages (SIMPER) revealed 53
percent similarity, with differences between pre- and post -Mod Alt L years driven by CPUE of
pinfish, Atlantic croaker, spot, and bay anchovy. Although there was a wide range of total CPUE
within both pre -Mod Alt L and post -Mod Alt L years (Table III-F6) comparison of interannual
variability between pre- and post -Mod Alt L fish assemblages within Tooley Creek by ANOSIM
detected spatial differences of statistical significance [Global R = 0.455; p = 0.010]. Total CPUE
for pre -Mod Alt L 2010 more than doubled total CPUE in all other sample years in Tooley Creek
and was the second highest total CPUE total encountered across all trawl creeks/years (Muddy
Creek 2003 was highest). The high total CPUE experienced in pre -Mod Alt L 2010 along with
increased Atlantic croaker catch and the decline in both pinfish and spot catch post -Mod Alt L set
post -Mod Alt years apart from pre -Mod Alt L years.
As indicated by statistically significant differences in interannual
variability between pre- and post -Mod Alt L fish assemblages in Tooley Creek, there were also
statistically significant differences among CPUE for four individual species between pre- and post -
Mod Alt L years. Of the nine managed species captured in Tooley Creek, Atlantic croaker
displayed significantly higher CPUE in combined post -Mod Alt L years than combined pre -Mod
Alt L years by t-test [small(n) = 65, big(n) = 130; T = 5,035.5; p = <0.001]; conversely, CPUE for
American eel in combined post -Mod Alt L years was significantly lower than combined pre -Mod
Alt L years [small(n) = 65, big(n) = 130; T = 7,199.0; p = <0.001]. As with managed species,
CPUE for commonly captured species such as bay anchovy, Atlantic silverside, rainwater killifish
and pinfish also displayed significant differences between pre- and post -Mod Alt L years. Bay
anchovy displayed significantly higher CPUE in combined post -Mod Alt L years than combined
pre -Mod Alt L years [small(n) = 65, big(n) = 129; T = 4,814.0; p = <0.001]. Although pinfish were
among the most abundant species captured in Tooley Creek in 1999, 2001 and 2010-2013, CPUE
of pinfish declined each year from 2011 until 2018, then seeing little to no capture in the three
sample years after (none captured 2016-2017, 2019 and 2021); however, 2018 pinfish CPUE was
the third highest for Tooley Creek across all years (Table III-F6). Driven by that decline, the CPUE
of pinfish in combined post -Mod Alt L years was significantly lower than combined pre -Mod Alt L
years [small(n) = 65, big(n) = 130; T = 8,514.0; p = <0.001] alongside Atlantic silverside [small(n)
= 65, big(n) = 130; T = 7,448.5; p = <0.001] and rainwater killifish [small(n) = 65, big(n) = 130; T
= 7,149.0; p = <0.001] (Figure III-F8).
Tooley Creek's pre- and post -Mod Alt L years were used to
compare variability among fish species composition and abundance for Atlantic croaker,
American eel, bay anchovy, Atlantic silverside, rainwater killifish and pinfish in Muddy Creek
(control). Muddy Creek exhibited similar trends in CPUE as Tooley Creek for all four species;
however, although CPUE of bay anchovy was higher in Muddy Creek in combined post -Mod Alt
L years, it was not statistically significant as in Tooley Creek. Total CPUE was also compared
between matching Tooley (2011-2021) and Long (2011-2021) years, a nearby control creek, to
compare variability for total abundances, the t-test did not display a statistical difference between
the two creeks.
III-F-8

v. Huddles Cut
The 2021 fyke nets for Huddles Cut represented the 18th year of
fish collections. Pre -Mod Alt L includes 1999-2001 and 2007-2009 and post -Mod Alt L is
comprised of 2010-2021. Community structure comparisons for Huddles Cut indicate that species
richness for 2000 (28 species) was the highest to date not only in Huddles Cut, but across all
creeks/years; furthermore, total abundance for 2020 (45,856 individuals) in Huddles Cut was the
largest number of individuals captured across all creeks/years, however mummichog made up
34,130 of the 45,856 total fish (74 percent) (Table III-F1). The 22 species captured in 2021 at
Huddles Cut was the highest species richness among all creeks sampled in 2021; likewise,
Huddles Cut comprised the top seven highest numbers of species captured across all
creeks/years (1999-2001, 2007, 2011-2014, and 2016-2021). As with species richness, total
abundance at Huddles Cut was often the highest of all creeks in a single sample year (15 of the
18 years) and comprised 11 of the 12 largest numbers of individuals captured across all
creeks/years (1999-2000, 2007-2008, 2010-2011, 2013, and 2018-2021) (Table III-F1). Both
mean species richness (22) and mean abundance (10,455) in Huddles Cut was highest among
the three fyke net creeks sampled from 2013-2021 by more than double (Table III-F1).
Multivariate cluster analysis of annual fish species composition and
abundance within Huddles Cut by a similarity profile test (SIMPROF) revealed a statistical
significance between years (Figure III-F9). Sample years in Huddles Cut formed the same three
clusters as the previous three years with the most recent year added into the same cluster for the
fourth time: cluster A consisted of post -Mod Alt L years 2014-2015, B contained the first three
pre -Mod Alt L years (1999-2001), and C contained all other years (2007-2013 and 2016-2021).
Comparison of interannual variability between all three clusters by similarity percentages
(SIMPER) revealed 62 percent similarity between B and C, 57 percent similarity between A and
C, and 47 percent similarity between A and B. Cluster A (2014-2015) contained the two lowest
total CPUEs for Huddles Cut across all years while clusters B and C separated primarily due to
dissimilarity in CPUE of pumpkinseed, Atlantic croaker, and mummichog and, to a lesser extent,
striped mullet (Figure III-F9 and Table III-F7).
Seven species were captured every year and another four species
were captured every year except one; of those seven, sheepshead minnow was among the top
five dominants in six post -Mod Alt L years, pumpkinseed was among the top five dominants only
in three pre -Mod Alt L years, while southern flounder was never among the top five at all (Table
III-F7). Among those seven species, mummichog had the highest CPUE for 14 years compared
to four for spot, CPUE for these two species highly influenced total CPUE of all species for each
year in Huddles Cut (Table III-F7). Elevated catches of these same two species contributed to
high CPUE in 1999, 2008, 2020 and 2021. Although spot catch increased in post -Mod Alt L 2016-
2020, the exceptionally high CPUE for spot captured from Huddles Cut in pre -Mod Alt L 1999 was
almost 170 times the CPUE of spot captured in post -Mod Alt L 2015 and 80 times the CPUE of
spot captured in post -Mod Alt L 2014. Along with spot and mummichog, total CPUE for Huddles
Cut each year was largely comprised of striped mullet, Atlantic menhaden, and pinfish. Thirteen
managed fish species were captured in Huddles Cut over the 18 years, the most of all sampled
creeks; summer flounder was present in 14 of the years but never as one of the top five dominants
(Table III-F7). The addition of blue catfish (lctalurus furcatus) (one individual) in 2017 brought the
freshwater species total to 15 of 47 total species captured in Huddles Cut with a total of 4,443
individuals, although CPUE for several has declined since the first two years. one of the four
species captured only in pre -Mod Alt L years were freshwater species while four of the ten species
captured only in post -Mod Alt L years were also freshwater (Table III-F7). While one of the seven
species captured every year as mentioned above, pumpkinseed was notable among the species
III-F-9

which declined since 1999, with 1999 CPUE decreasing by nearly a third in 2000, to 25 times less
in 2001, and to a lesser extent from 2007 through 2021 (Table III-F7).
Comparison of interannual variability between pre- and post -Mod
Alt L annual fish assemblages within Huddles Cut by similarity percentages (SIMPER) revealed
63 percent similarity, with differences between pre- and post -Mod Alt L years driven by CPUE of
spot, pumpkinseed, striped mullet, mummichog, Atlantic croaker, and pinfish. Total CPUE for
both pre -Mod Alt L 1999 and 2008 nearly doubled, or more than doubled, total CPUE for most
post -Mod Alt L years until 2019; however, comparison of interannual variability between pre- and
post -Mod Alt L fish assemblages within Huddles Cut by ANOSIM detected no spatial differences
of statistical significance likely because of the record high in total CPUEs set in post -Mod Alt L
2020 and 2021 (Table III-F7). Post -Mod Alt L years comprised seven of the nine lowest total
CPUE encountered for the 18 Huddles Cut years; low total CPUE in pre -Mod Alt L 2009 (third
lowest total CPUE) and 2014 (second lowest total CPUE) are believed to be the direct effect of
the formation of a sandbar at the creek mouth in 2008 or 2009 that blocked and/or limited fish
access into and out of the creek; the sandbar location is dynamic but it appears to have affected
catch to various degrees for all subsequent years. Species richness and abundance at Huddles
Cut was usually higher than all other creeks/years and total post -Mod Alt L CPUE increased since
2015 to the third highest CPUE of all years in 2019, second highest in 2021 and the highest in
2020 which resulted in no significant difference between pre- and post -Mod Alt L years (Table III-
F7).
Some statistically significant differences were found among CPUE
for individual species between pre- and post -Mod Alt L years in Huddles Cut. Of the 13 managed
species captured in Huddles Cut, spot [small(n) = 77, big(n) = 156; T = 11,178.0; p = <0.001],
striped mullet [small(n) = 77, big(n) = 156; T = 10,242.5; p = 0.010], Atlantic croaker [small(n) =
77, big(n) = 156; T = 11,613.0; p = <0.001], American eel [small(n) = 77, big(n) = 156; T = 9,708.0;
p = 0.009], and summer flounder [small(n) = 77, big(n) = 156; T = 9,795.0; p = 0.013] displayed
significant differences among CPUE between pre- and post -Mod Alt L years by means of t-test,
with lower CPUE in the combined post -Mod Alt L years than the combined pre -Mod Alt L years
(Figure III-F10). Red drum displayed a significantly higher CPUE in post -Mod Alt L years [small(n)
= 77, big(n) = 156; T = 8,050.5; p = 0.002] (Figure III-F10). As with the aforementioned managed
species, CPUE for commonly captured species, such as pumpkinseed [small(n) = 77, big(n) =
156; T = 11,470.5; p = <0.001] and Atlantic silverside (Menidia menidia,) [small(n) = 77, big(n) =
156; T = 9,734.0; p = 0.038], also displayed significantly lower CPUE in the combined post -Mod
Alt L years than combined pre -Mod Alt L years; conversely, CPUE of sheepshead minnow
[small(n) = 77, big(n) = 156; T = 6,877.0; p = <0.001] and Inland silverside [small(n) = 77, big(n)
= 156; T = 7,062.0; p = <0.001] in the combined post -Mod Alt L years was significantly higher
than the combined pre -Mod Alt L years (Figure III-F10).
vi. Porter Creek
The 2021 trawls for Porter Creek represented the 11 th year of fish
collections and the sixth post -Mod Alt L year. The first five years comprise pre -Mod Alt L (2011-
2015) and 2016-2021 comprise post -Mod Alt L. Community structure comparisons for Porter
Creek indicate that species richness ranged from seven species captured in 2016 to 15 in 2015;
the seven species captured in Porter Creek equaled Muddy Creek for the second lowest number
of species captured across all creeks in 2016 and tied nine other creek/years for the second
lowest across all creek/years (Table III-F1). Total abundance for Porter Creek ranged from 665
individuals in 2011 to 4,425 in 2020. Among the seven trawled creeks from 2011-2021, mean
III-F-10

species richness was lowest (10) in both Porter Creek and Long Creek, and mean abundance
(2,385) was in Porter Creek was second highest (Table III-F1).
Multivariate cluster analysis of annual fish species composition and
abundance within Porter Creek by a similarity profile test (SIMPROF) revealed slight variation but
no statistically significant differences between years. Fish assemblages within Porter Creek
predominantly consisted of spot, Atlantic croaker, bay anchovy, and Atlantic menhaden, with an
increase of pinfish in 2012 (the only year pinfish was among the top five dominants). While pinfish
was present in seven of the 11 years, hogchoker was present in 10 and was one of the top five
in three (Table III-F8). Six managed fish species were captured in Porter Creek over the 11 years
and the addition of white catfish (one individual) in 2020 made a total of six freshwater species
out of 24 total species captured in Porter Creek. In addition to the white catfish, bluegill (two
individuals in 2018), eastern mudminnow (two individuals in 2012), golden shiner (12 individuals
in 2015), largemouth bass (one individual in 2015 and 2019), and pumpkinseed (two individuals
in 2017 and three individuals in 2018) were the six freshwater species captured at Porter Creek
(Table III-F8). Among those six species, two were found only pre -Mod Alt L while three were
found only post -Mod Alt L.
Comparison of interannual variability between pre- and post -Mod
Alt L annual fish assemblages within Porter Creek by similarity percentages (SIMPER) revealed
77 percent similarity, with differences between pre- and post -Mod Alt L years driven by CPUE of
Atlantic croaker, spot, Atlantic menhaden, and bay anchovy. Total CPUE for Porter Creek has
fluctuated throughout the 11 sample years and comparison of interannual variability between pre -
and post -Mod Alt L fish assemblages within Porter Creek by ANOSIM detected no spatial
differences of statistical significance (Table III-F8).
There were statistically significant differences among CPUE for two
species between pre- and post -Mod Alt L years. Of the six managed species captured in Porter
Creek, only summer flounder displayed significant differences among CPUE between pre- and
post -Mod Alt L years by means of t-test, with lower CPUE in the combined post -Mod Alt L years
than the combined pre -Mod Alt L years [small(n) = 65, big(n) = 78; T = 5,031.0; p = <0.001].
Among the commonly captured other species, bay anchovy represented the only other significant
change with an increase post -Mod Alt L [small(n) = 65, big(n) = 78; T = 4,025.0; p = 0.008] (Figure
III-F11).
Porter Creek's pre- and post -Mod Alt L years were used to compare
variability among fish species composition and abundance for summer flounder and bay anchovy
in Duck Creek (control). Duck Creek exhibited similar trends in CPUE as Porter Creek for both
species; however, neither was statistically significant as in Porter Creek.
vii. DCUT11
The 2021 fyke nets for DCUT11 represented the ninth year of fish
collections (2013-2021) and the fourth post -Mod Alt L year. Community structure comparisons
for DCUT11 indicate that species richness ranged from 10 species in 2013 to 21 in 2019 with a
mean of 16 species over the period (Table III-F1). Although total abundance at DCUT11
increased each year since 2018 and reached a high in 2021 (2,725), total abundance for the first
four years was amongst the lowest across all creeks/years, although species richness over the
years was seldom among the lowest (Table III-F1).
III-F-11

Multivariate cluster analysis of annual fish species composition and abundance within DCUT11
by a similarity profile test (SIMPROF) revealed no statistically significant differences between
years. Fish assemblages within the DCUT11 drainage basin consisted of pumpkinseed and
mummichog each year, and usually eastern mosquitofish was also a dominant; mummichog and
pumpkinseed alone have accounted for greater than 40 percent of the total catch in each year. In
2020 spot increased to 1,056 individuals and 2021 saw mummichog capture increase to 1,825
individuals, by far the highest CPUE for both species in all years. Four managed fish species were
captured in DCUT11 over the nine years and 21 of 33 total species captured were freshwater
species; these 21 species were the largest number of freshwater species captured across all
creeks. Additionally, with 4,637 individuals, DCUT11 had the highest percentage of freshwater
individuals captured in any creek since 2013 (Table III-F9).
Comparison of interannual variability between pre- and post -Mod
Alt L annual fish assemblages within DCUT11 by similarity percentages (SIMPER) revealed 51
percent similarity, with differences between pre- and post -Mod Alt L years driven predominantly
by CPUE of spot, pumpkinseed, and mummichog. Although total CPUE in post -Mod Alt L for
2019, 2020 and 2021 more than tripled total annual CPUE for pre -Mod Alt L years 2014-2017
(Table III-F9), comparison of interannual variability between pre- and post -Mod Alt L fish
assemblages within DCUT11 by ANOSIM detected no spatial differences of statistical
significance.
There were statistically significant differences among CPUE for two
species between pre- and post -Mod Alt L years. Of the four managed fish species spot displayed
significant differences among CPUE between pre- and post -Mod Alt L years by means of t-test,
with higher CPUE in post -Mod Alt L 2018-2021 than the combined pre -Mod Alt L years [small(n)
= 52, big(n) = 65; T = 3,521.0; p = <0.001]. Of the commonly captured species in DCUT11,
pumpkinseed [small(n) = 52, big(n) = 65; T = 4,029.5; p = <0.001], sheepshead minnow [small(n)
= 52, big(n) = 65; T = 3,352.0; p = 0.042] and rainwater killifish [small(n) = 52, big(n) = 65; T =
3,501.0; p = <0.001] also displayed significant differences between pre- and post -Mod -Alt L years
with higher CPUEs in post -Mod Alt L years (Figure III-F12).
DCUT11's pre- and post -Mod Alt L years were used to compare
variability among fish species composition and abundance for pumpkinseed and spot in DCUT19
(control). DCUT19 exhibited similar trends in CPUE as DCUT11 for pumpkinseed, rainwater
killifish, sheepshead minnow and spot with all also showing statistically higher CPUE in post -Mod
Alt L years.
c. Mod -Alt L Control Creeks
i. SCUT1
The 2021 trawls for SCUT1 represented the third year of fish
collections. Eleven different species were captured at SCUT1 in 2019, 10 in 2020 and eight in
2021 for a cumulative total of 13 (Table III-F1). The mean species richness of eight at SCUT1
represented the lowest in all creeks. Mean total abundance (901) for SCUT1 was the second
lowest of all creeks, behind Broomfield Swamp Creek; however, even though Broomfield Swamp
Creek abundance was the lowest all sampled creeks for 2020 and 2021, there are only three
years of data for these two upper South Creek tributaries (Table III-F1).
Atlantic croaker, spot, and bay anchovy represented the highest
III-F-12

CPUE within SCUT1 while Atlantic menhaden was one of the top five dominants only in 2019
(Table III-F10). Three managed fish species were captured in SCUT1 in 2019-2021 (Atlantic
croaker, Atlantic menhaden, and spot) and five of 13 total species captured were freshwater
species with 2021 representing the highest percentage of freshwater fish. These freshwater
species comprised 94 individuals (Table III-F10).
ii. Little Creek
The 2021 trawls for Little Creek represented the 11th year of fish
collections (2011-2021). Community structure comparisons for Little Creek indicate that species
richness ranged from seven in 2017 and 2021 to 19 in 2012; total abundance increased the first
three years to 2,861 individuals in 2013 and fluctuated in years since reaching a high of 3,037 in
2020 (Table III-F1). The seven species captured in 2017 and 2021 in Little Creek equaled nine
other trawl creek/years for the second lowest number of species captured across all creeks/years.
Mean species richness in Little Creek (13) was in the midrange and mean abundance (1,608)
was the lowest among all trawled creeks from 2011-2021 (Table III-F1).
Multivariate cluster analysis of annual fish species composition and
abundance within Little Creek by a similarity profile test (SIMPROF) revealed slight variation of
statistical significance between years (Figure III-F13). Sample years in Little Creek formed two
clusters: cluster A consisted of 2014-2017 and 2019-2021 and B contained 2011-2013 and 2018.
Comparison of interannual variability between clusters A and B by similarity percentages
(SIMPER) revealed 56 percent similarity with differences driven predominantly by CPUE of
pinfish, Atlantic croaker, spot, and eastern mudminnow. Dissimilarity between total CPUE of
clusters A and B was primarily driven by increased CPUE of Atlantic croaker and decreased
CPUE of pinfish, spot, and eastern mudminnow in years grouped within A; the eastern
mudminnow was not captured 2014-2021 and only 25 individuals of pinfish were captured over
the same period, with none captured in 2015, 2017, 2019 and 2021 (Figure III-F13 and Table III-
F11).
Fish assemblages within Little Creek predominantly consisted of
spot, bay anchovy, Atlantic croaker, and Atlantic menhaden with spot and Atlantic croaker as the
top two most abundant species captured 2014-2017 and 2019-2021. Pinfish and inland silverside
were also among the most abundant species captured in Little Creek with pinfish among the top
five dominants in five out of the seven years it appeared while inland silverside was present in
nine of the 11 years but among the five dominants in only four years (Table III-F11). Eastern
mudminnow was among the five dominants in the first three years but has not been caught since
2013. Although present in eight of the 11 years, since the increase of naked goby in 2013, the
species has had low to no catch in all other years. Nine managed fish species were captured in
Little Creek over the 11 years; never among the dominants but often present in the early years,
American eel has not been captured since 2016 and while southern flounder has been present
for eight of the 11 years it was among the top five dominants only twice (2017 and 2019) (Table
III-F11). The addition of largemouth bass (one individual) in 2020 made a total of seven freshwater
species out of 34 total species captured in Little Creek. In addition to bluegill and largemouth
bass, pumpkinseed, eastern mudminnow, eastern mosquitofish, banded killifish, and longnose
gar (Lepisosteus osseus) were the seven freshwater species captured at Little Creek (Table III-
F11).
III-F-13

PA2
The 2021 trawls for PA2 represented the 11th year of fish collections
(2011-2021). Community structure comparisons for PA2 indicate that species richness which
varied less than any other creek in the study to date from a low of 15 species captured in 2018 to
a high of 21 in 2019; the 21 species captured in 2019 was tied with DCUT 11 for second highest
species richness among all creeks in 2019 and was the highest of all trawl creeks/years (Table
III-F1). Total abundance for PA2 ranged from 1,639 individuals in 2016 to 6,269 in 2021 which
was also the highest abundance since 2011 among the 12 trawled creeks; since 2011 PA2 has
contained the highest abundance of these creeks in seven of the 11 years. Mean species
richness (18) and mean abundance (4,127) in PA2 were the highest among all trawled creeks
from 2011-2021 (Table III-F1).
Multivariate cluster analysis of annual fish species composition and
abundance within PA2 Creek by a similarity profile test (SIMPROF) revealed slight variation of
statistical significance between years (Figure III-F14). Sample years formed two clusters: Cluster
A contained 2014-2021 and cluster B contained 2011-2013. Comparison of interannual variability
between clusters A and B by similarity percentages (SIMPER) revealed 52 percent similarity with
differences driven predominantly by CPUE of eastern mudminnow, rainwater killifish and pinfish.
Dissimilarity between clusters A and B was primarily driven by a decrease of eastern mudminnow
and pinfish and an increase in rainwater killifish in the later sample years (Figure III-F14 and Table
III-F12).
Fish assemblages within PA2 predominantly consisted of spot,
rainwater killifish, pinfish, inland silverside, and Atlantic menhaden, with fluctuations of
pumpkinseed and eastern mudminnow in earlier years; no eastern mudminnow were captured
2014-2021. 2021 saw an influx of brown bullhead (Ameiurus nebulosus) with 1,344 individuals
captured, marking the species most prevalent year (Table III-F12). Ten (10) managed fish
species were captured in PA2 over the 11 years with the capture of red drum in 2019; American
eel was present every year and Atlantic croaker was present in eight of the 11 years, but neither
of these species was ever among the top five dominants. 10 of 34 total species captured were
freshwater species. The 10 freshwater species comprised 8,718 individuals; however, eastern
mudminnow alone accounted for 3,248. These 8,718 individuals at PA2 represent the largest
number of freshwater individuals captured across all creeks (Table III-F12). Among all creeks in
the study to date, PA2 and Long Creek are the only creeks whose annual total CPUE was never
below 100 in any year.
iv. Long Creek
The 2021 trawls for Long Creek represented the 11th year of fish
collections (2011-2021). Community structure comparisons for Long Creek indicate that species
richness ranged from six in 2017 and 2021 to 17 in 2012; the six species captured in 2017 and
2021 both tied for the lowest species richness in their respective years. Long Creek in both 2017
and 2021 equaled five other creeks/years for the lowest number of species captured across all
creeks/years (Table III-F1). Total abundance ranged from 1,415 individuals in 2017 to 2,826 in
2012. Mean species richness in Long Creek (10) was tied with Porter Creek for the lowest, and
mean abundance (2,185) was the fourth highest among all trawled creeks from 2011-2021 (Table
III-F1).
Multivariate cluster analysis of annual fish species composition and
abundance within Long Creek by a similarity profile test (SIMPROF) revealed no statistically
III-F-14

significant differences between years. Fish assemblages within Long Creek predominantly
consisted of spot, Atlantic croaker, bay anchovy, and Atlantic menhaden and pinfish,
predominately captured in the early years. Nine managed fish species were captured in Long
Creek over the 11 years with the addition of bluefish in 2019; among the managed species
captured less frequently, southern flounder was present in six of the years but among the five
dominants only three times in more recent years (2017 and 2020-2021) while summer flounder
was present in five of the years and never was among the five dominants (Table III-F13). Only
two of 25 total species captured were freshwater species; eastern mudminnow (14 individuals,
none in the last eight years) and eastern mosquitofish (six individuals in one of the eleven years,
but also none in the last eight) were the two freshwater species captured at Long Creek (Table
III-F13).
v. Muddy Creek
The 2021 trawls for Muddy Creek represented the 22nd year of fish
collections (1999-2005 and 2007-2021). Community structure comparisons for Muddy Creek
indicate that both species richness and total abundance were highest in 2003 with a total catch
of 7,894 individuals among 18 species (2015 species richness was also 18 but with more than
four times less abundance) (Table III-F1). Species richness within Muddy Creek ranged from six
species in 2007 to 18 in both 2003 and 2015, with a mean of 13 species over 21 years. The six
species captured at Muddy Creek in 2007 tied six other creek/years for lowest species richness
among all creeks/years (Table III-F1). Total abundance for Muddy Creek was lowest in 2017 (757
individuals, the first year <1,000 but that year was on the low end of abundance for most creeks)
and total abundance in 2003 (7,894 individuals) represented the largest number of individuals
captured across all trawl creeks/years and eighth largest across all creeks/years (Table III-F1).
Mean species richness (13) across all trawl creeks/years ranked near the middle and mean
abundance across all trawl creek/years (2,971) was second highest behind PA2 (4,127) (Table
III-F1).
Multivariate cluster analysis of annual fish species composition and
abundance within Muddy Creek by a similarity profile test (SIMPROF) revealed statistical
significance between years (Figure III-F15). Sample years in Muddy Creek formed three clusters:
Cluster A contained 2001, 2002, 2008, 2009, 2012, 2013 and 2018; cluster B contained 2000,
2003-2005, 2007, 2014-2017 and 2019-2021 and cluster C contained 1999 and 2011.
Comparison of interannual variability between clusters by similarity percentages (SIMPER)
revealed 60 percent similarity between A and B with differences driven predominantly by CPUE
of Atlantic croaker and pinfish, cluster A and C were 52 percent similar with differences driven
predominantly by CPUE of pinfish, bay anchovy, spot, Atlantic croaker and inland silverside and
there was a 42 percent similarity found between B and C with differences drive predominantly by
CPUE of Atlantic croaker, bay anchovy and rainwater killifish. Cluster C (1999 and 2011)
contained low CPUE of Atlantic croaker and spot, and as with most of the creeks, CPUE for both
Atlantic croaker and spot typically dominated total catch and highly influenced total CPUE of all
species each year. The combination of both low Atlantic croaker and spot catch with low catches
of secondary species (i.e., pinfish and bay anchovy) attributed to two of the four lowest total
CPUEs across all years in Muddy Creek and caused 1999 and 2011 to cluster separately (Figure
III-F15 and Table III-F14).
Spot dominated fish assemblages within Muddy Creek and
influenced total catch in all years and had the highest CPUE every year but one until Atlantic
croaker became the most predominant fish in 2021; other than spot and Atlantic croaker, fish
III-F-15

assemblages within Muddy Creek predominantly consisted of bay anchovy, Atlantic menhaden,
pinfish, and inland silverside (Table III-F14). Pinfish CPUE varied greatly and ranged from no
catch (2004, 2005, 2007, 2014, 2016, 2019 and 2021) to one of the top five most abundant
species in nine of the 22 sample years. Eleven (11) managed fish species were captured in
Muddy Creek over the 22 years, the second most behind Huddles Cut. Twelve (12) of 37 total
species captured were freshwater species, the most of all trawl creeks; however, no more than
four of these 12 were ever captured in one year (1999 and 2015), two of the 12 were caught only
once, common carp (Cyprinus carpio) and yellow perch (Perca flavescens), and six years had
none (Table III-F14).
vi. DCUT19
The 2021 fyke nets for DCUT19 represented the ninth year of fish
collections (2013-2021). Community structure comparisons for DCUT19 indicate that species
richness ranged from 12 species in 2020 to 23 in 2015; the 23 species captured in 2015 was the
highest number of species captured across all creeks in 2015 and was exceeded only by Huddles
Cut in four years (1999, 2000, 2013, and 2020) across all creeks/years (Table III-F1). Total
abundance ranged from 530 individuals in 2015 to 11,233 in 2020; total abundance for DCUT19
was the second lowest among all creeks in 2015 and the second highest among all creeks in
2020 (Table III-F1).
Multivariate cluster analysis of annual fish species composition and abundance within DCUT19
by a similarity profile test (SIMPROF) revealed slight variation but no statistically significant
differences between years. Fish assemblages within the DCUT19 drainage basin predominantly
consisted of pumpkinseed (highest CPUE in five of the years), mummichog (highest CPUE in four
of the years), spot, and sheepshead minnow; these four species alone accounted for greater than
60 percent of the total catch each year. Seven managed fish species were captured in DCUT19
over the nine years with the addition of red drum in 2019; striped mullet was present in six out of
the nine years, but neither it nor other managed species were ever among the top five dominants
(Table III-F15). Twenty-one (21) of 40 total species captured were freshwater species which tied
DCUT11 for the highest number of freshwater species caught among all creeks. Pumpkinseed
(3,059 individuals) and eastern mosquitofish (918 individuals) accounted for 3,977 of the total
4,926 freshwater individuals; individuals of freshwater species captured at DCUT19 were the
second largest number of freshwater individuals captured across all creeks behind PA2 (Table
III-F15).
vii. Duck Creek
The 2021 trawls for Duck Creek represented the 11th year of fish
collections (2011-2021). Community structure comparisons for Duck Creek indicate that species
richness ranged from seven species in 2014 and 2019 to 19 in 2013; the seven species captured
in 2014 equaled nine other creeks/years for the second lowest number of species captured across
all creeks/years (Table III-F1). Total abundance ranged from 364 individuals in 2011 to 5,150 in
2020; total abundance for Duck Creek in 2011 was the 10th lowest across all creeks/years and
seventh lowest number of individuals captured across all trawl creeks/years. Mean species
richness in Duck Creek (12) was tied with Tooley Creek for the fourth lowest number and mean
abundance (1,645) was the fourth lowest among all creeks trawled behind Broomfield Swamp
Creek, SCUT1 and Little Creek (Table III-F1).
III-F-16

Multivariate cluster analysis of annual fish species composition and
abundance within Duck Creek by a similarity profile test (SIMPROF) revealed statistically
significant differences between years (Figure III-F16). Sample years in Duck Creek formed four
clusters: cluster A consisted of 2011, cluster B consisted of 2012-2013, C contained 2011 and
2014 and 2019-2021 and D consisted of 2015-2018. Comparison of interannual variability by
similarity percentages (SIMPER) revealed 49 percent similarity between A and B, 53 percent
between A and C, 63 percent between A and D, 58 percent between B and C, 60 percent between
B and D and 66 between C and D. 2011 represented the lowest CPUE of all Duck Creek sample
years and grouped alone as a result, cluster B contained 2012 and 2013, the only years where
eastern mudminnow were capture and dissimilarity within groups D and C was primarily driven
by differences in CPUE of spot, Atlantic croaker and bay anchovy (Figure III-F16 and Table III-
F16).
Fish assemblages within Duck Creek predominantly consisted of
spot, Atlantic croaker, and bay anchovy. Both Atlantic menhaden and pinfish were also among
the most abundant species captured at Duck Creek; however, from the highest total CPUE in
2011, Atlantic menhaden catch trended downward in most years before an increase in 2018-2020
and pinfish were not caught in 2014, 2017, 2019 and 2021. Eight managed fish species were
captured in Duck Creek over the 11 years; summer flounder were present in eight of the years
and southern flounder in nine but neither as one of the top five dominants (Table III-F16). The
addition of brown bullhead in 2020 (six individuals) and spottail shiner (Notropis hudsonius) in
2021 made a total of nine freshwater species out of 31 total species captured in Duck Creek.
These nine freshwater species comprised 155 individuals; however, two species, eastern
mudminnow (49 individuals) and bluegill (47 individuals) accounted for 96 of the 150 (Figure III-
F16 and Table III-F16).
2.0 Summary and Conclusions
Dissimilarities among years in the 10 trawled creeks with pre- and post -Mod Alt L
data is mostly driven by CPUE differences among spot, Atlantic croaker, bay anchovy, Atlantic
menhaden, and pinfish, with other fish represented to a lesser degree in some creek/years.
Interannual comparisons between pre- and post -Mod Alt L years indicated no
statistically significant spatial differences for four of the seven creeks with post -Mod Alt L data
(Jacobs, Porter, Huddles Cut, and DCUT11); however, spatial differences of significance were
detected between pre- and post -Mod Alt L fish assemblages within Jacks Creek, Drinkwater
Creek and Tooley Creek [Global R = 0.287; p = 0.010, Global R = 0.544; p = 0.018 and Global R
= 0.455; p = 0.010, respectively]. In addition to interannual comparisons of total CPUE,
differences in CPUE of various individual species also displayed statistically significant
differences between pre- and post -Mod Alt L years for all seven creeks with post -Mod Alt L data.
Low total CPUE for Jacks, Drinkwater, and Tooley creeks in both post -Mod Alt L
2016 and post -Mod Alt L 2017 was likely the driver that set post -Mod Alt years apart from pre -
Mod Alt L years. Either 2016 or 2017 represented the lowest total CPUE experienced in seven
of 10 creeks sampled by trawl with post -Mod Alt L years; furthermore, both 2016 and 2017
represented two of the three lowest total CPUE's in eight of 10 trawl creeks. Low CPUE observed
locally throughout South Creek and its tributaries in both 2016 and 2017 caused post -Mod Alt L
fish assemblages of Jacks Creek to be most affected, as 2016-2017 comprise two of seven post -
Mod Alt L years. Control creek/years matched to Jacks, Drinkwater, and Tooley creeks pre- and
post -Mod Alt L years were analyzed to compare variability between fish assemblages as a whole
III-F-17

and variability among composition and abundance of fish species commonly captured between
creeks. When arranged to match the pre- or post -Mod Alt L years, Muddy Creek exhibited similar
trends in both total CPUE and CPUE of individual fish species as both Jacks and Tooley creeks;
however, corresponding years in Muddy Creek often did not display differences of statistical
significance between total CPUE as did both Jacks and Tooley creeks. Available matching years
for Little Creek were also compared to Jacks where trends were similar for six of seven fish,
however only five of the seven species showed statistical differences between pre- and post -Mod
Alt L years. Likewise, both control creeks PA2 and Long displayed similar trends in CPUEs as
Drinkwater Creek with greater similarity in CPUE of individual fish species; five of six individual
species in Long and PA2 had significant differences in CPUE between corresponding years.
The fish data illustrate the extreme natural variability in fish catch among all
creeks/years, in both the control creeks and creeks with drainage basin reduction, making it very
difficult to discern any mine -related spatial patterns in fish abundance. The longer fish data sets
have also established baseline ranges of CPUE for the most common species and data from
future years can be compared to these abundances. Though it is not likely that small differences
in abundance will be detected, it may be possible to discern large-scale changes in abundances
of the most common fishes over time; even so, it may still be difficult to attribute any noted large-
scale changes to a particular factor or influence.
