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
2020 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
revealed 12 distinct groups among all the sampled creeks which are discussed in Section II-D.
When appropriate, additional cluster analysis and comparisons of each particular creek for all
species and/or comparisons of particular species within specific creeks was done, and if
necessary, those results were compared to control creeks. Extra analyses were done 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 F15 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 2020 trawls for Broomfield Swamp Creek represented the
second year of fish collections and the second pre -Mod Alt L year. Sixteen (16) different
species have been captured over the two collection years (Table III-F1). The 11 species
captured in Broomfield Swamp Creek in 2020 tied with Muddy Creek for third lowest species
richness of all creeks in 2020. Total abundance for Broomfield Swamp Creek was the lowest of
all creeks in 2020 (142 individuals) and the second lowest ever recorded behind only Jacks
2016 (119) (Table III-F1).
Spot (Leiostomus xanthurus), bluegill (Lepomis macrochirus), bay
anchovy (Anchoa mitchilli), and Atlantic croaker (Micropogonias undulatus) represented the
highest CPUEs within Broomfield Swamp Creek in 2020 (Table III-F2). Bay anchovy accounted
for the highest CPUE in 2020 and second highest in 2019 within Broomfield Swamp Creek while
Atlantic menhaden (Brevoortia tyrannus), most dominant in 2019, was not captured in 2020.
Three managed species were captured over the two years while two of those were captured in
Broomfield Swamp Creek both years (Atlantic croaker, and spot) and seven of 16 total species
captured were freshwater species. These freshwater species comprised of 208 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 2020 trawls for Jacks Creek represented the 17th year of fish
collections and the sixth post -Mod Alt L year. Eleven years comprise pre -Mod Alt L (1999-2005
and 2011-2014) and 2015-2020 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 17 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 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 fourth
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). Sample years in Jacks
Creek formed the same four clusters as 2019 with the 2020 data year added into cluster C:
cluster A again 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 D and three in C. Comparison
of interannual variability between all four clusters by similarity percentages (SIMPER) revealed
57 percent similarity between clusters C and D, 52 percent similarity between B and D, 46
percent similarity between A and C, 45 percent similarity between B and C, 35 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 four lowest total CPUEs for Jacks Creek across all years with
differences between the two clusters driven predominantly by CPUE of rainwater killifish
(Lucania parva), spot, and pumpkinseed (Lepomis gibbosus). Cluster C primarily consisted of
both early years (2000, 2003-2005) and later years (2014, 2015, 2019 and 2020) 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
(Lagadon rhomboides) and rainwater killifish. Cluster D formed the fourth 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 C; additionally, D had lower CPUE of both Atlantic
croaker and Atlantic menhaden (Figure III-F1 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, along with 2018 and 2019, each had CPUEs less
than 100 while the long term average CPUE for 1999-2020 collection years was 163.9. Although
2020 had a CPUE of 230.38, post -Mod Alt L CPUE (92.58) remained 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 (Paralichthys dentatus), 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 and 2019 when Atlantic croaker dominated total CPUE (Table III-F3). During
III-F-2

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 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 2014-2020. Three species were caught 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 17 years and 11 of 37 total species captured were freshwater species; however, 1999
represented the most freshwater species captured with seven while 12 of the 17 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 four times higher than the post -Mod Alt L total (3) (Table III -
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 to a lesser extent, Atlantic croaker. Total CPUE for Jacks Creek has
increased/decreased throughout most years with no definitive trend; however, as stated earlier,
four of five years with the lowest total 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 since 2016 with 2020 total CPUE the highest to date, 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 = 0.255; p = 0.027] 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
six 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 three of the six post -Mod Alt L years. The lower total CPUE in five of the six
combined post -Mod Alt L years and overall decline in dominant species such as both spot and
pinfish at Jacks Creek in five of the six 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, and 2017 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, southern flounder (Paralichthys lethostigma), and American eel (Anguilla
rostrata) 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) = 78, big(n) = 144; T = 6,300.5; p = <0.001], for summer
flounder [small(n) = 78, big(n) = 144; T = 7,433.0; p = <0.001], for southern flounder [small(n) =
III-F-3

78, big(n) = 144; T = 9,283.0; p = 0.038], and for American eel [small(n) = 65, big(n) = 144; T =
6,250.5; p = 0.015] (Figure III-F2). As with managed species, CPUE for commonly captured
species such as bay anchovy and pinfish in combined post -Mod Alt L years was significantly
lower than combined pre -Mod Alt L years [small(n) = 78, big(n) = 144; T = 7,685.0; p = 0.020
and small(n) = 78, big(n) = 144; T = 6,813.0; p = <0.001], respectively (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, southern flounder, American
eel, bay anchovy, and pinfish in Muddy Creek (control). Muddy Creek exhibited similar trends in
CPUE as Jacks Creek for all five species; however, American eel, southern flounder and bay
anchovy in Muddy Creek did not display statistically significant differences in CPUE between
combined pre -Mod Alt L years and combined post -Mod Alt L years. 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 2015-2020 for post -Mod Alt L). Little Creek exhibited similar trends
for all species; however, spot and bay anchovy 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 (2011-2020) and Little years (2011-2020) to compare
variability for total abundances, the t-test did not display a statistical difference between the two
creeks.
ii. Jacobs Creek
The 2020 trawls for Jacobs Creek represented the 10th year of fish
collections. The first three years comprise pre -Mod Alt L (2011-2013) and 2014-2020 comprise
post -Mod Alt L. Community structure comparisons for Jacobs Creek indicate that species
richness ranged from 10 in 2019, 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 fourth largest number of individuals captured across all trawl creeks
for 2011 through 2020 behind only PA2 (2014 and 2020) and Duck Creek (2020). Mean
species richness (16) in Jacobs Creek was the second highest behind PA2 and mean
abundance (2,446) was the fourth highest behind Muddy, Tooley, and PA2 among all trawled
creeks from 2011-2020 (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 two clusters:
cluster A consisted of post -Mod Alt L years 2016-2017 and 2019 and B 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 and B by similarity percentages (SIMPER) revealed
48 percent similarity with differences driven predominantly by low CPUE of pinfish, spot, and
rainwater killifish in the three post -Mod Alt L years in A; post -Mod Alt L 2019 saw zero captures
of both rainwater killifish and pinfish; post -Mod Alt L 2016-2017 had the lowest pinfish and spot
CPUEs for Jacobs Creek across all years excluding 2019 for pinfish, in addition to only 15 total
individuals of rainwater killifish captured for post -Mod Alt L 2016-2017 (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
III-F-4

post -Mod Alt L (2014-2020) (Table III-F4). Five species have been captured every year of the
study, Atlantic croaker, bay anchovy, spot, hogchoker (Trinectes maculatus), and inland
silverside (Menidia beryllina); however, the last two species were among the five dominants only
once (Table III-F4). Ten (10) managed fish species were captured in Jacobs Creek over the ten
years; six of them were never among the top five dominants, although three were present in five
or more of the years (Table III-F4). Seven of 34 total species captured were freshwater species
and comprised 617 individuals (eastern mudminnow alone accounted for 433); two freshwater
species were captured pre -Mod Alt L while six 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 56 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 10 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) = 91; T = 3,135.0; p = <0.001] and American
eel [small(n) = 39, big(n) = 91; T = 2,889.5; p = 0. 008] and higher CPUE in post -Mod Alt L
years for Atlantic croaker [small(n) = 39, big(n) = 91; T = 1759.5; p = <0.001]. The CPUE for
commonly captured species such as pinfish and eastern mudminnow in combined post -Mod Alt
L years was also significantly lower than combined pre -Mod Alt L years small(n) = 39, big(n) =
91; T = 3447.0; p = <0.001 and small(n) = 39, big(n) = 91; T = 3,510.0; p = <0.001, respectively
(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, and eastern mudminnow 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 five species; however,
although CPUE of Atlantic croaker in PA2 was higher in combined post -Mod Alt L years it was
not statistically significant as in Jacobs Creek.
Drinkwater Creek
The 2020 trawls for Drinkwater Creek represented the tenth year
of fish collections. The first two years comprise pre -Mod Alt L (2011-2012) and 2013-2020
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 10 species in 2019 and was
back up to 17 in 2020; 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 (Table III-F1). Conversely, total abundance for Drinkwater Creek
increased the first three years then decreased each of the next three years to a low of 368
III-F-5

individuals captured in 2016, then began a general upward trend through 2020; 2016 total
abundance was the second lowest across all creeks trawled in 2016 and was the sixth lowest
across all trawl creeks/years. Mean species richness in Drinkwater Creek (15) was the third
highest and mean abundance (1,672) was the third lowest among all trawled creeks from 2011-
2020 (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 and 2019) 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 56 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 five 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
fluctuations in catches of rainwater killifish and inland silverside represented the most abundant
species captured nearly each year; 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, Atlantic menhaden, and rainwater killifish); only spot was in the top five all 10
years (Table III-F5). Ten managed fish species were captured in Drinkwater Creek over the ten
years and seven of 33 total species captured were freshwater species. These seven species
comprised 198 individuals; however, although the eastern mudminnow declined each year with
none captured in 2014-2020, 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 56 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 post -Mod Alt L 2018-2020 compared to previous recent years, 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 = 0.496; p = 0.022].
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) = 104; T = 1,093.0; p = <0.001] and both
American eel [small(n) = 26, big(n) = 104; T = 1,984.5; p = 0. 002] and summer flounder
[small(n) = 26, big(n) = 104; T = 1,973.0; 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 and eastern
mudminnow in combined post -Mod Alt L years was significantly lower than combined pre -Mod
III-F-6

Alt L years small(n) = 26, big(n) = 104; T = 2,676.0; p = <0.001 and small(n) = 26, big(n) = 104;
T = 2,522.0; p = <0.001, respectively (Figure III-F6).
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, and eastern mudminnow 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 five species; however, although CPUE of Atlantic
croaker was also higher in post -Mod Alt L years in PA2 it was not statistically significant as in
Drinkwater Creek.
iv. Tooley Creek
The 2020 trawls for Tooley Creek represented the 14th year of fish
collections (1999-2001 and 2010-2020). Pre -Mod Alt L years consisted of 1999-2001 and 2010-
2011, and post -Mod Alt L year were comprised of 2012-2020. Community structure
comparisons for Tooley Creek indicate that species richness ranged from a low of six in both
2016 and 2017 to 17 in both 1999 and 2013; 2016 and 2017 were the lowest species richness
encountered in both years and equaled Muddy Creek in 2007 and both Jacks Creek and Long
Creek in 2017 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 fourth lowest number of individuals captured across all trawl creeks/years
and the fifth 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 and the ninth highest number of individuals captured across all 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 and mean abundance
(2,491) 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 (2014-2020), 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 30 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 dominated fish assemblages within Tooley Creek every year
but 2017 and influenced total catch in all years; in addition to spot, other dominants 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 (Caranx hippos) in 2017 with just one
III-F-7

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 14 years sampled. American eel, summer and southern flounder were present in
seven of the years, but only southern flounder was among the top five dominants (2017 and
2020) (Table III-F6). Eight of 33 total species captured were 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 = 0.403; 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) = 117; T = 4,851.5; 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) = 117; T = 6,666.0; p = <0.001]. As with managed species,
CPUE for commonly captured species such as both bay anchovy 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) = 116; T = 4,647.0; 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 (none captured 2016-2017 or 2019); 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) = 117; T = 7,792.5; 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, and pinfish in Muddy Creek (control). Muddy Creek exhibited
similar trends in CPUE as Tooley Creek for all four species; however, although CPUE of
American eel was lower 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
III-F-8

Tooley (2011-2020) and Long (2011-2020) years, a nearby control creek, to compare variability
for total abundances, the t-test did not display a statistical difference between the two creeks.
v. Huddles Cut
The 2020 fyke nets for Huddles Cut represented the 17th year of
fish collections. Pre -Mod Alt L includes 1999-2001 and 2007-2009 and post -Mod Alt L is
comprised of 2010-2020. 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). Frequently
across the years, the 24 species captured in 2020 at Huddles Cut was the highest species
richness among all creeks sampled in 2020 and was the fourth highest species richness among
all creeks/years; likewise, Huddles Cut comprised the top six highest numbers of species
captured across all creeks/years (1999-2001, 2007, 2011-2014, and 2016-2020). As with
species richness, total abundance at Huddles Cut was often the highest of all creeks in a single
sample year (14 of the 17 years) and comprised 10 of the 12 largest numbers of individuals
captured across all creeks/years (1999-2000, 2007-2008, 2010-2011, 2013, and 2018-2020)
(Table III-F1). Both mean species richness (22) and mean abundance (9,841) in Huddles Cut
was highest among the three fyke net creeks sampled from 2013-2020 (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 two years with the most recent year added into the same cluster for the
third 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 2016-2020).
Comparison of interannual variability between all three clusters by similarity percentages
(SIMPER) revealed 63 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 (Mugil cephalus) (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 (Cyprinodon
variegatus) was among the top five dominants only in five 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 13 years compared to four for spot, and 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 and 2020.
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 17 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).
III-F-9

The addition of blue catfish (Ictalurus furcatus) (one individual) in 2017 brought the freshwater
species total to 15 of 47 total species captured in Huddles Cut with a total of 4,370 individuals,
although CPUE for several has declined since the first two years. Two of the five 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 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 2020 (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 CPUE set in post -
Mod Alt L 2020 (Table III-F7). Post -Mod Alt L years comprised seven of the nine lowest total
CPUE encountered for the 17 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. In addition to lower total CPUE in post -Mod
Alt L years, and unlike all six pre -Mod Alt L years, three of the 11 post -Mod Alt L years did not
include spot as one of the top two abundant species captured. 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 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) = 143; T = 10,657.5; p =
<0.001], striped mullet [small(n) = 77, big(n) = 143; T = 9,746.5; p = 0.005], Atlantic croaker
[small(n) = 77, big(n) = 143; T = 10,517.0; p = <0.001], American eel [small(n) = 77, big(n) =
143; T = 9,150.0; p = 0.017], and summer flounder [small(n) = 77, big(n) = 143; T = 9,164.5; p =
0.030] 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) = 143; T = 7,830.5; p = 0.010] (Figure III-F10). As with the
aforementioned managed species, CPUE for commonly captured species such as pumpkinseed
also displayed significantly lower CPUE in the combined post -Mod Alt L years than combined
pre -Mod Alt L years [small(n) = 77, big(n) = 143; T = 10,828.0; p = <0.001]; conversely, CPUE
of sheepshead minnow in the combined post -Mod Alt L years was significantly higher than the
combined pre -Mod Alt L years [small(n) = 77, big(n) = 143; T = 6,569.5; p = <0.001] (Figure III-
F10).
vi. Porter Creek
The 2020 trawls for Porter Creek represented the tenth year of
III-F-10

fish collections and the fifth post -Mod Alt L year. The first five years comprise pre -Mod Alt L
(2011-2015) and 2016-2020 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. In addition to Muddy Creek in
2016 and 2019, species richness in Porter Creek in 2016 also equaled both Long Creek and
Duck Creek in 2014 and 2019 and Little Creek in 2017 for the second lowest number of species
captured across all creeks/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 2011-2020
mean species richness was lowest (10) in both Porter Creek and Long Creek, and mean
abundance (2,376) was in Porter Creek was third 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 10 years, hogchoker was present in nine
and was one of the top five in three (Table III-F8). Six managed fish species were captured in
Porter Creek over the 10 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 10 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) = 65; T = 4,550.0; p =
0.002]. 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) = 65; T = 3,779.0; p =
0.026] (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.
III-F-11

vii. DCUT11
The 2020 fyke nets for DCUT11 represented the eighth year of
fish collections (2013-2020) and the third 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 15 species over the period (Table III-F1). Although total abundance at
DCUT11 increased each year since 2018 and reached a high in 2020 (2,524), total abundance
for the first four years was amongst the lowest in the across all creeks/years although species
richness over the years was seldom among the lowest (Table III-F1).
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
(Gambusia holbrooki) 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, by far the highest CPUE for the species in all years with none captured in
three of the previous seven years. Four managed fish species were captured in DCUT11 over
the eight 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
4,023 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 50
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 and 2020 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 2018-2020 than the combined pre -Mod Alt
L years [small(n) =39, big(n) = 65; T = 2,431.5; p = <0.001]. Of the commonly captured species
in DCUT11, pumpkinseed also displayed significant differences between pre- and post -Mod -Alt
L years with higher CPUE in post -Mod Alt L years [small(n) = 39, big(n) = 65; T = 2,897.0; p =
<0.001] (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 both pumpkinseed and spot with both also showing
statistically higher CPUE in post -Mod Alt L years.
c. Mod -Alt L Control Creeks
i. SCUT1
The 2020 trawls for SCUT1 represented the second year of fish
collections. Eleven different species were captured at SCUT1 in 2019 and 10 in 2020 for a
cumulative total of 12 (Table III-F1). The 10 species captured in SCUT1 in 2020 was the
III-F-12

second lowest number of species in all creeks. Mean total abundance (1,254) for SCUT1 was
the third lowest of all creeks, behind DCUT11 and Broomfield Swamp Creek; however, even
though Broomfield Swamp Creek abundance was the lowest all sampled creeks for 2020, there
are only two years of data for these two upper South Creek tributaries (Table III-F1).
Atlantic croaker, spot, and bay anchovy represented the highest
CPUE within SCUT1 across both years 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 2019-2020 (Atlantic croaker, Atlantic menhaden, and spot) and four of 12 total species
captured were freshwater species. These freshwater species comprised 48 individuals (Table
III-F10).
ii. Little Creek
The 2020 trawls for Little Creek represented the tenth year of fish
collections (2011-2020). Community structure comparisons for Little Creek indicate that species
richness ranged from seven in 2017 to 19 in 2012, while total abundance increased the first
three years to 2,861 individuals in 2013, decreased each of the next four years to a low of 527
captured in 2017, then increased again in 2018 to 1,414, to 1,036 in 2019, and then to a high of
3,037 individuals in 2020 (Table III-F1). The seven species captured in 2017 in Little Creek
equaled both Long Creek and Duck Creek in 2014 and both Muddy Creek and Porter Creek in
2016 for the second lowest number of species captured across all creeks/years. Mean species
richness in Little Creek (14) was in the midrange and mean abundance (1,661) was second
lowest among all trawled creeks from 2011-2020 (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 2019-2020 and B contained 2011-
2013 and 2018. Comparison of interannual variability between clusters A and B by similarity
percentages (SIMPER) revealed 57 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 2014-2020 and only 25 individuals of pinfish were
captured over the same period, with none captured in 2015, 2017 and 2019 (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, 2019, and 2020. 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 seven years while inland silverside was present in
nine of the 10 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 10 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 10 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 seven of the 10 years it was among the top five dominants only twice (2017
III-F-13

and 2019) (Table III-F11). The addition of bluegill (one individual) in 2018 and 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).
PA2
The 2020 trawls for PA2 represented the tenth year of fish
collections (2011-2020). 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 6,144 in 2020 which was also the highest abundance since 2011 among the 12 trawled
creeks; PA2 abundance was also highest among these 12 creeks in 2011 (4,649 individuals),
2013 (4,069 individuals), 2015 (3,514 individuals), 2017 (4,629 individuals) and 2019 (4,749
individuals). Mean species richness (18) and mean abundance (3,913) in PA2 were the highest
among all trawled creeks from 2011-2020 (Table III-F1).
Multivariate cluster analysis of annual fish species composition
and abundance within PA2 by a similarity profile test (SIMPROF) revealed slight variation but no
statistically significant differences between years. Fish assemblages within PA2 predominantly
consisted of spot, rainwater killifish, pinfish, inland silverside, and Atlantic menhaden, with
fluctuations eastern mudminnow in earlier years; no eastern mudminnow were captured 2014-
2020 (Table III-F12). Ten (10) managed fish species were captured in PA2 over the ten years
with the capture of red drum in 2019; American eel was present every year and Atlantic croaker
was present in eight of the years but neither of these species was ever among the top five
dominants. Nine of 34 total species captured were freshwater species. The nine freshwater
species comprised 6,172 individuals; however, eastern mudminnow alone accounted for 3,248.
These 6,172 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 2020 trawls for Long Creek represented the tenth year of fish
collections (2011-2020). Community structure comparisons for Long Creek indicate that
species richness ranged from six in 2017 to 17 in 2012; the six species captured in 2017
equaled both Jacks Creek and Tooley Creek for the lowest species richness in 2017. In
addition to both Jacks Creek and Tooley Creek, species richness in Long Creek in 2017 also
equaled Muddy Creek in 2007 and Tooley Creek in 2016 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 2011-2020 (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
significant differences between years. Fish assemblages within Long Creek predominantly
III-F-14

consisted of spot, Atlantic croaker, bay anchovy, and Atlantic menhaden, with fluctuations of
pinfish each year except 2014, 2016, 2017 and 2019 when no pinfish were captured. Nine
managed fish species were captured in Long Creek over the ten 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 twice in more recent years (2017
and 2020) 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 seven years) and eastern mosquitofish (six
individuals in one of the ten years, but also none in the last seven) were the two freshwater
species captured at Long Creek (Table III-F13).
v. Muddy Creek
The 2020 trawls for Muddy Creek represented the 21 st year of fish
collections (1999-2005 and 2007-2020). 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 equaled Tooley Creek in 2016 and Jacks, Long,
and Tooley creeks in 2017 for lowest species richness among all creeks/years; although Duck
Creek in 2014 and 2019, Long Creek in 2014 and 2019, Porter Creek in 2016, Muddy Creek in
2016 and 2019, and Little Creek in 2017 all had seven species (Table III-F1). Total abundance
for Muddy Creek was lowest in 2017 (757 individuals, the first year <1,000 but the 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 equaled Duck for fourth lowest and mean abundance across all trawl creek/years
(3,065) was second highest behind PA2 (3,913) (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-F14). Sample years in Muddy Creek formed two clusters:
cluster A contained 1999 and 2011 and cluster B contained all other years. Comparison of
interannual variability between clusters by similarity percentages (SIMPER) revealed 47 percent
similarity between A and B with differences driven predominantly by CPUE of Atlantic croaker,
spot, bay anchovy, and pinfish. Cluster A (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-F14 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; other than
spot, fish assemblages within Muddy Creek predominantly consisted of bay anchovy, Atlantic
croaker, Atlantic menhaden, pinfish, and inland silverside (Table III-F14). Pinfish CPUE varied
III-F-15

greatly and ranged from no catch (2004, 2005, 2007, 2014, 2016 and 2019) to one of the top
five most abundant species in 1999, 2001, 2002, 2008, 2009, 2010, 2012, 2013, and 2018.
Eleven (11) managed fish species were captured in Muddy Creek over the 21 years, the second
most behind Huddles Cut. Twelve (12) of 36 total species captured were freshwater species,
the most of all trawl creeks (Jacks Creek was second at 11); however, no more than four of
these 13 were ever captured in one year (1999 and 2015), three of the 13 were caught only
once, brown bullhead (Ameiurus nebulosus), common carp (Cyprinus carpio) and yellow perch
(Perca flavescens), and six years had none (Table III-F14).
vii. DCUT19
The 2020 fyke nets for DCUT19 represented the eighth year of
fish collections (2013-2020). Community structure comparisons for DCUT19 indicate that
species richness ranged from 12 species in 2020 (the lowest number for this creek to date) 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 previous 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 three 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 eight years with the addition of red
drum in 2019; striped mullet was present in six out of the eight years, but neither it nor other
managed species were ever among the top five dominants (Table III-F15). Eighteen (18) of 38
total species captured were freshwater species, the second highest number of freshwater
species captured across all creeks (behind DCUT11 at 21). Pumpkinseed (2,470 individuals)
and eastern mosquitofish (370 individuals) accounted for 2,840 of the total 3,299 freshwater
individuals; individuals of freshwater species captured at DCUT19 were the third largest number
of freshwater individuals captured across all creeks behind PA2 and Huddles Cut, respectively
(Table III-F15).
vii. Duck Creek
The 2020 trawls for Duck Creek represented the tenth year of fish
collections (2011-2020). 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 Long Creek for the lowest species richness in 2014 and equaled
Muddy and Long creeks for lowest species richness in 2019. Species richness for Duck in 2014
and 2019 also equaled both Muddy Creek and Porter Creek in 2016 and Little Creek in 2017 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 eighth lowest across all creeks/years and fifth lowest number of
individuals captured across all trawl creeks/years. Mean species richness in Duck Creek (13)
was tied with Muddy Creek for the fourth lowest and mean abundance (1,614) was the third
lowest among all creeks trawled behind Broomfield Swamp Creek and SCUT1 from 2011-2020;
III-F-16

however, these Broomfield Swamp Creek and SCUT1 have only two years of data (Table HI-
FI).
Multivariate cluster analysis of annual fish species composition
and abundance within Duck Creek by a similarity profile test (SIMPROF) revealed statistically
significan differences between years (Figure III-F15). Sample years in Duck Creek formed two
clusters: cluster A consisted of 2012-2013 and B contained 2011 and 2014-2020. Comparison
of interannual variability between clusters A and B by similarity percentages (SIMPER) revealed
58 percent similarity with differences driven predominantly by CPUE of pinfish, Atlantic croaker,
spot, bay anchovy and eastern mudminnow. Dissimilarity between total CPUE of clusters A and
B was primarily driven by increased CPUE of pinfish, spot, and eastern mudminnow and
decreased CPUE of Atlantic croaker and bay anchovy in the two years grouped in A; the
eastern mudminnow was captured only in 2012 and 2013 (Figure III-F15 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 and 2019. Eight managed fish species were
captured in Duck Creek over the ten years; both southern flounder and summer flounder were
present in eight of the years but never as one of the top five dominants (Table III-F16). The
addition of channel catfish (Ictalurus punctatus) (two individuals) in 2017 and brown bullhead in
2020 (six individuals) made a total of eight freshwater species out of 30 total species captured in
Duck Creek. These eight freshwater species comprised 150 individuals; however, two species,
eastern mudminnow (49 individuals) and bluegill (47 individuals) accounted for 96 of the 150
(Figure III-F15 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 = 0.255; p = 0.027, Global R = 0.496; p = 0.022. and Global
R = 0.403; 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; 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 six post -Mod Alt L years.
III-F-17

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 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 CPUE as did both Jacks and Tooley creeks. Available matching years for
Little Creek were also compared to Jacks where trends were similar for all six fish, however only
four of the six 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; all five individual species in
Long and four out of five individuals in 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 abundant fish over time; even so, it may still be difficult to attribute any
noted large-scale changes to a particular factor or influence.
