CCS Biological Characterization Study 1 FPL Turkey Point Cooling Canal System Characterization Study Executive Summary A baseline biological characterization study was conducted in the Florida Power and Light Company (FPL) Turkey Point Cooling Canal System (CCS) in December 2016. The purpose of this work was to provide an understanding of the fish and invertebrate populations within the CCS, as well as to determine if there was any seagrass remaining in the system. Key findings from this work: The CCS is a unique, closed system that has hypersaline, warm water with poor clarity and areas of dissolved oxygen below 4.0 mg/L. Temperature readings are consistent with previous observations, where temperature decreases with increasing distance from the discharge. Fish and mobile invertebrate communities have low diversity, are made up of species tolerant to CCS water conditions, and are spatially variable in abundance. Benthic macroinvertebrate communities in the CCS have extremely low diversity, species richness, and abundance. No evidence of living submerged aquatic vegetation (SAV) was detected at any of the stations sampled during this study. The results of this study concur with similar research at other power plants which have documented lower species richness and diversity for fish populations in areas impacted by the thermal influence of power plant water discharges. Increased salinity levels within the CCS potentially contribute to the low diversity and abundance of fish, mobile invertebrate, and benthic macroinvertebrate communities. A summary of findings from the biological characterization study is provided in Table 1.

CCS Biological Characterization Study 3 Introduction This Supplemental Evaluation establishes a baseline biological characterization of the CCS at the FPL Turkey Point Plant, Miami-Dade County, Florida. This study was conducted on December 5-7, 2016. The study qualitatively characterized fish and invertebrate populations, SAV, and benthic macroinvertebrates resident within the CCS using various sampling techniques. The work was conducted by Ecological Associates Inc. (EAI) with oversight by Ecology & Environment Inc. (E&E) on behalf of FPL. These efforts answered the following questions: Knowledge Gaps 1.Is there a healthy and diverse fish and mobile invertebrate community in the CCS? 2.Is SAV present in the CCS, and if present, in which sections/areas of the CCS? 3.Is there a healthy and diverse benthic macroinvertebrate community in the CCS? 4.What is the baseline abundance, diversity, and distribution of fish, mobile invertebrates, and benthic macroinvertebrates within the CCS? Purpose The purpose of this study was to determine what organisms were living within the CCS. Fish and mobile invertebrates were sampled throughout the CCS using nets and traps. Benthic macroinvertebrates living in canal sediments were sampled using benthic mini-ponar grabs. Underwater video was used to search for any living SAV in the CCS. This initial baseline biological characterization study attempted to characterize the CCS ecosystem variability by spatially distributing the sampling stations during the single collection event. The data provided meets the following project goal: Identify the species present, their relative abundance and distribution during baseline CCS sampling, so changes over time in the biotic community may be used to gauge effects from CCS management efforts. Station Locations Ten stations within the CCS were established for water quality, fish and mobile invertebrate, SAV, and benthic macroinvertebrate sampling. The location of these sampling stations were chosen to represent different benthic habitats (e.g., recently dredged/undredged, shallow/deep, and rocky/silty), salinity gradients, and temperature regimes within the study area (Figure 1 and Appendix A). Stations 1 through 7 were located within the cooling canals west of the Grand Canal, while Stations 8 and 9 were located in the return canals east of the Grand Canal. Station 10 was located in a dead-end canal in the northern section of the Grand Canal. An airboat provided by FPL and operated by plant personnel was used to access the stations and conduct the sampling program. Results Field sampling was conducted December 5-7, 2016. The sampling protocol provided qualitative estimates of species diversity and density for floral and faunal residents in the FPL Turkey Point CCS. These data, although precise counts are included, are intended only to provide an estimate of relative abundance (e.g., low, moderately abundant, or highly abundant) for the organisms reported, and not a precise quantitative assessment of species abundance and distribution.
CCS Biological Characterization Study 4 A summary of findings is provided in Table 1. The SAV data are reported as present or absent. Fish and mobile invertebrate communities are characterized by relative population abundance within the CCS. Abundance at each station is considered "low" if combined cast net and fish trap sampling yielded less than 300 individuals, "moderate" if between 301 and 600 individuals, and "high" if greater than 600 individuals were collected. Fish and mobile invertebrate communities are also characterized by species richness. Species richness at each station is considered "low" for 5 or less taxa, "moderate" for 6 to 15, and "high" for over 15 taxa. Benthic macroinvertebrate density is reported as "low" for 100 individuals/m² or less, "moderate" from 101 and 500 individuals/m², and "high" for greater than 500 individuals/m². Benthic macroinvertebrate Shannon-Weiner diversity is considered "low" for calculated values less than 1.0000, "moderate" for 1.0001 to 2.0000, and "high" for values over 2.0000. Species richness is considered "low" if 5 or less taxa were captured, "moderate" for 6 to 15, and "high" for greater than 15 taxa. Evenness is considered "low" for calculated values less than or equal to 0.250, "moderate" for values between 0.251 and 0.500, and "high" for values over 0.500. Evenness could not be calculated for stations with only one species; stations with one species are categorized as "low" evenness. Some stations have high evenness values, however this calculated value is skewed due to low abundance and species richness, and should therefore be considered with caution. General Canal System Observations Many birds were observed throughout the FPL Turkey Point Plant CCS. In three days of sampling, bird sightings included snowy egrets (Egretta thula), little blue herons (Egretta caerulea), tricolored herons (Egretta tricolor), reddish egrets (Egretta rufescens), great egrets (Ardea alba), roseate spoonbills (Platalea ajaja), wood storks (Mycteria americana), and American white pelicans (Pelecanus erythrorhynchos). Birds were frequently observed feeding in the shallow areas in the cooling canal system north and northwest of the docks near the Land Utilization building (Figure 2). A yellow-crowned night heron (Nyctanassa violacea) was observed at Station 7. A double-crested cormorant (Phalacrocorax auritus), an American avocet (Recurvirostra americana), and a great blue heron (Ardea herodias) were observed near Station 9 on the shoreline. Belted kingfishers (Megaceryle alcyon) were seen in the trees in the northern section of the return canal system while traveling along canal E-6 and at Station 10. Osprey (Pandion haliaetus) were observed flying over the CCS, but were not observed actively fishing in the CCS. Although these bird observations are qualitative, the abundance and diversity of piscivorous birds indicates that the population of fish within the CCS provide ample feeding opportunities. Water Quality Water quality parameters were collected on December 6, 2016, during minnow trap deployment, and again on December 7 during minnow trap retrieval. A summary of the water quality data collected over the two days is presented in Appendix B. Water clarity ranged from 0.5-1.0 foot. Recorded total water depths at sampling stations were between 1 and 14 feet, with a mean water depth of 2.6 feet for stations 1-9, and 14 feet for Station 10. Water temperatures were warmer by 1-3 °C at all stations on December 7 compared to December 6. Minimum and maximum water temperatures ranged from 26.48 °C to 37.23 °C. Temperature generally decreased with increasing distance from the discharge canal. Specific conductance and its derivative, salinity, ranged from a low of 81,900 µS/cm at Stations 4 (58.33 PSU) and 7 (58.07 PSU) to a high of 86,100 µS/cm at Station 10 (61.96 PSU). Specific conductance and salinity generally increased with increasing distance from the discharge canal. Dissolved oxygen values ranged from 0.21 CCS Biological Characterization Study 5 mg/L at Station 10 (the deepest station) to 7.18 mg/L at Station 4 (the shallowest station). During sampling, pH values were similar between stations, ranging from 7.78 (Station 9) to 8.06 (Station 7). Water quality parameters varied day-to-day and from site-to-site. Long-term water quality data is a more effective way to characterize CCS water quality parameters influenced by spatial or seasonal trends. In summary, the Turkey Point CCS is a hypersaline body of water with high temperatures and areas of dissolved oxygen below 4.0 mg/L. A combination of these water quality parameters are likely the contributing factors that limit fish, mobile invertebrate, and benthic macroinvertebrate diversity and abundance, and potentially act as contributing factors limiting SAV presence. Submerged Aquatic Vegetation Surveys Submerged aquatic vegetation (SAV) surveys were conducted on December 5-6, 2016. Water clarity was poor (1 foot or less) throughout the entire project area (Appendix B). No SAV was found during the video transect surveys (Appendix C). To ensure that SAVs were not overlooked due to poor visibility, mini-ponar grab samples used for benthic macroinvertebrate collections were also scanned for living vegetation. No SAV was found during the benthic macroinvertebrate sampling. The lack of SAV is likely due to the turbid water conditions currently found in the CCS, although high salinity and temperature can also negatively impact seagrass. High turbidity, unrelated to extreme salinity or temperature regimes, have been correlated with seagrass loss in other areas of Florida (Indian River Lagoon 2011 Consortium, 2015). Some of the stations were also located in areas where dredging has occurred, which may have removed evidence of prior SAV presence. Fish and Invertebrates Collected During Cast Net Sampling Cast net sampling, designed to target large mobile organisms located throughout the entire water column, was conducted on December 5, 2016. A total of 282 fish representing three species were collected during cast net sampling (Appendix D). No invertebrates were captured. The most abundant fish collected was the sheepshead minnow (Cyprinodon variegatus)with 259 individuals, followed by the sailfin molly (Poecilia latipinna) with 22 individuals, and the eastern mosquitofish (Gambusia holbrooki) with a single specimen collected. The number of fish collected at each station ranged from 10 individuals at Station 7 to eighty-four (84) at Station 10. All fish collected were small; even the largest fish were less than 45 mm (1.75 inches) Standard Length (SL). Sheepshead minnows ranged from 11-38 mm SL (Appendix F). Sailfin mollies ranged from 30-45 mm SL (Figure 3). The single eastern mosquitofish captured was 30 mm SL. Fish length data for the Turkey Point CCS is within normal size ranges for the species captured, however this is a low diversity system since only three fish species were captured. Fish and Invertebrates Collected During Minnow Trap Sampling Minnow traps were deployed on December 6 and retrieved on December 7, 2016, after having fished for 23-25 hours (Figure 4). The traps, located at the top and bottom of the water column, were designed to selectively target small, cryptic species not well sampled by cast net survey techniques. A total of 4,561 specimens representing three species of fish and one species of crustacean were collected using surface and bottom minnow traps (Appendix E). Similar to cast net sampling, the most abundant fish collected was the sheepshead minnow with 3,900 individuals, followed by 627 sailfin mollies, and 20 eastern mosquitofish.
CCS Biological Characterization Study 6 Sheepshead minnows were more abundant in the bottom minnow traps, as would be expected for a demersal species. The exceptions to this generalization were Stations 7 and 10. Station 7 was so shallow that there was no observable depth difference in the surface and benthic minnow trap pair, where both traps extended out of the water. Station 10 was anoxic at the bottom, so only a few fish were collected in the bottom minnow trap and some had already expired by the time the trap was retrieved. For all stations combined, sailfin molly specimenswere more abundant in the surface fish traps, although a few more individuals of this species were collected in the bottom traps at Stations 1, 7, and 9. Sailfin mollies feed on surface algae and floating detritus, or on benthic algal mats, and perform aquatic surface respiration to compensate for hypoxic water conditions (Timmerman and Chapman, 2004a), so it would be expected that more individuals would be captured in surface minnow traps. Eastern mosquitofish were only captured at Station 7 in the bottom minnow trap and Station 10 in the surface minnow trap. At Station 7, the water depth was shallow and both surface and bottom traps were visible at the water surface, so fishing depth was identical in surface and bottom minnow traps. A total of 14 mudflat fiddler crabs (Uca rapax) were collected from surface and bottom minnow traps. The fiddler crabs were captured in bottom minnow traps at Stations 3, 4, and 8, and from the surface minnow trap at Station 4. The depth at Station 4 was so shallow that both minnow traps were resting on the substrate, but were visible at the water surface. The total number of individual fish and invertebrates collected at each station ranged from a low of 160 specimens at Station 8, to a maximum of 1,062 specimens at Station 4. Fish specimens captured ranged from 10-60 mm SL; the smallest was a sailfin molly and the largest was a sheepshead minnow (Appendix G). The size of the mudflat fiddler crabs captured ranged from 8-11 mm Carapace Length (CL) and 11-15 mm Carapace Width (CW), which is nearing the reported maximum size for this species.There were no visual sightings of large fish or invertebrate species while in transit or on station in the main section of the CCS during sampling. In the canal leading to Station 10, there were thousands of eastern mosquitofish, which all appeared to reside in the upper 1-2 cm of the water column. Fish and Invertebrate Summary In summary, 4,843 individuals comprising 4 taxa (i.e., 3 fish and 1 crustacean species) were collected during this study using cast net and minnow trap sampling techniques (Table 2). Sheepshead minnows were found at all 10 sampling stations and are projected to be abundant throughout the cooling canal system (Figure 5). This species is known to live and successfully reproduce in water with high salinity (up to 147 PSU) and high temperatures (up to 43
°C) (Johnson, 1974). The hypersaline, high temperature, and lower DO levels within the CCS are within the tolerated range for sheepshead minnows (Peterson, 1990). The specimens captured during this study have standard length ranges similar to those documented in other research, suggesting that there are no obvious impacts on the size of individuals because of the environment (Johnson, 1974). Sailfin mollies were collected at 9 sampling stations, but at a much lower abundance than the sheepshead minnows. This species is moderately abundant throughout the CCS. It also is a species considered to be tolerant of high salinity (up to 80 PSU), high temperatures (up to 40
°C), and low dissolved oxygen (down to CCS Biological Characterization Study 7 1 mg/L) (Nordlie et al., 1992; Fischer & Schlupp, 2009; Timmerman & Chapman, 2004). The salinity and temperature recorded within the CCS during this study are well within the physiological tolerance limits of the sailfin molly. The sailfin mollies collected in the CCS are within the normal size range for adults, although some of the recorded standard lengths suggest that there was a mixture of juveniles and adults captured (Trexler and Travis, 1990). There is no indication that the environmental conditions in the CCS limit normal growth for sailfin mollies. Eastern mosquitofish were only found at Stations 7 and 10 may be rare within the CCS as a whole. However, opportunistic observations suggest eastern mosquitofish may be locally abundant. Eastern mosquito fish can tolerate low dissolved oxygen levels and have been captured in areas with DO as low as 0.39 mg/L (Edwards et al., 2006). Mosquitofish (and sailfin mollies) have dorsally oriented mouths and a flattened head profile that facilitates taking in oxygen-rich water at the atmosphere-water interface or gulping air (Pyke, 2005). This species can tolerate warm (up to at least 38
°C) and hypersaline water (up to 58.8 PSU) (Specziar, 2004; Chervinski, 1983). Temperatures above 30
°C are considered stressful for the species, resulting in a smaller overall size, earlier maturity, and smaller brood sizes (Meffe, 1992). However, the standard lengths of the adult eastern mosquitofish specimens captured are similar to those collected in other studies (Beaudouin et al., 2008). The spatial variability of the eastern mosquitofish is likely due to temperature, since the portion of the CCS located near the discharge is warmer than the optimal temperature range for the species. Mudflat fiddler crabs were the only crustaceans captured (Figure 6). Adults of this species can tolerate a wide range in salinity (1.7-139 PSU) and have been documented in areas with dissolved oxygen down to 0.8 mg/L (Zanders & Rojas, 1996; Costa & Soares-Gomes, 2015). Water temperatures recorded during this study are within the thermal tolerance of mudflat fiddler crabs, which can survive temperatures up to 44
°C (Vernberg & Tashian, 1959). Specimens were collected from Stations 3, 4, and 8 at a low abundance. The sampling methods used during this study were not designed to capture fiddler crabs, and therefore incidental catches of the mudflat fiddler in minnow traps cannot properly assess mudflat fiddler crababundance in the Turkey Point CCS. Fiddler crabs are highly mobile crustaceans which have the capability of recruiting over the earthen dikes separating the CCS from Biscayne Bay. Without incorporating meroplankton sampling into the study design, which could capture crab larval stages, we cannot determine whether the mud flat fiddler crabs are reproducing within the CCS or recruiting by immigration. In summary, fish and mobile invertebrate diversity was low throughout the CCS. The taxa recorded are tolerant species with physiological adaptations that permit survival in warm, hypersaline, and low dissolved oxygen conditions. No evidence was found indicating that the environmental conditions within the Turkey Point CCS negatively affected growth or reproduction in the extremophile fish captured by this study based on the proscribed sampling methods.

Three (3) taxa totaling 79 individuals were identified from the 10 stations combined (Table 3). The polychaete Capitella capitata, marine oligochaetes (Class Oligochaeta), and midge larvae (Family Chironomidae) were the only taxa captured. No benthic macroinvertebrates were found at Stations 1, 2, 6, 7, and 10. Comparisons between dredged vs. non-dredged, or spatial locations should not be made since the total number of specimens collected was extremely low and the replicate number of stations in each habitat type was too few to allow meaningful comparisons between habitat types. The polychaete Capitella capitata was the most common taxon collected (n=70). Capitella capitata is considered to be a fast colonizing species that is tolerant of a wide variety of stressors, including low dissolved oxygen (Tsutsumi, 1987). Capitella capitata populations need dissolved oxygen levels above 1 mg/L to survive, and the only documentation of dissolved oxygen dropping below that level within the CCS was at Station 10. Oligochaetes are generally abundant and widespread in marine sediments, yet a mere 8 specimens were captured. Oligochaetes may be indicative of stressed habitats (Leppakoski, 1975). Midges are rare in marine environments, but two marine species are known from Florida. For the stations with benthic macroinvertebrates present, the calculated densities were low to moderate, ranging from 30 individuals/square meter (m²) at Stations 3 and 5, to 489 individuals/m² at Station 8. For stations with organisms present, species richness was low. Stations 3, 4, and 9 had the fewest taxa, represented by a single species, and Stations 5 and 8 the most (2 taxa). The Shannon-Weiner Diversity Index was calculated for each station to compare the distribution of taxa relative to the total number of specimens collected. A higher Shannon-Weiner Index number represents a more diverse community. Shannon-Weiner Diversity Index values were lowest at stations with only a single taxon (Stations 3, 4, and 9), and highest at Station 5 (0.6931). Species evenness, a measurement of how evenly distributed (numerically) each species is at a site, was also calculated. A species evenness of 1 means an equal number of individuals of each species is present. Evenness was highest at Station 5 (1.000) due to a single specimen collected in each of two taxa present within the sample. Evidence of relic gastropod and bivalve shells were present at some stations in the CCS, however no live mollusc specimens were collected during sampling. Since the molluscs were not alive upon collection, the remains were not identified or enumerated. The mollusc shells did not appear to be fossil shells produced from dredged marine sediments, but instead were molluscs that died in the CCS relatively recently. Historic water quality conditions in the CCS may have been more conducive to sustaining mollusc populations than they currently are
.In summary, the Turkey Point CCS had benthic macroinvertebrate communities with low abundance, low species richness, and low diversity at all sampling stations. The few species present were indicative of stressful benthic environments. The hypersaline, warm water and potentially anoxic benthic environment has undoubtedly limited the recruitment and establishment of benthic macroinvertebrate communities.

CCS Biological Characterization Study11 DiscussionWater quality data collected during the December 2016 baseline characterization study of the CCS at the FPL Turkey Point Plant shows that there is some spatial variability within the system. Temperature generally decreased with increasing distance from the discharge, as would be expected. Specific conductance and salinity increased marginally with increasing distance from the discharge at Stations 1, 2, 3, 5, and 6, but Stations 4 and 7 have lower values. Stations 8 and 9, in the return canal, and Station 10 in the dead-end canal generally have slightly higher specific conductance and salinity than stations located in the eastern discharge canals. Dissolved oxygen (DO) levels varied throughout the CCS, but were noticeably lower at Station 10, the deepest station sampled, compared to the rest of the CCS. DO was lower at the beginning and end of the cooling system, and higher DO at the middle stations (i.e., Stations 3-7). Higher water temperatures near the discharge reduce DO holding potential, and the deeper return canal system has a reduced surface-to-volume ratio for oxygen diffusion. Stations 3-7 are cooler, shallow canals where wind and wave action can more effectively aerate the water. The water quality data collected as part of this study was a snapshot to provide general insight into conditions within the CCS and to see how this may affect the organisms living within the system. Long-term water quality data collections would be a more reliable measure to base organismal distribution and density interpretations on. No SAV was observed during this study. Benthic macroinvertebrate abundance, species richness, and diversity were extremely low across all sites. Fish and mobile invertebrate data collected during cast net and minnow trap sampling indicates that abundance is spatially variable throughout the system and diversity is low. Eastern mosquitofish appeared to be rare throughout the system as a whole, but are potentially locally abundant. Conversely, the sheepshead minnow and sailfin molly were found throughout the entire CCS and often in moderately abundant numbers. Higher temperatures may be less tolerable to the eastern mosquitofish, limiting their range to the cooler stations, further from the discharge, within the CCS. The abundant piscivorous wading birds observed throughout the CCS confirm the presence of a relatively abundant fish population. The results of this study concur with similar studies which documented decreased species richness and diversity for fish populations in areas impacted by the thermal influence of power plant water discharges (Teixeira et al., 2012). Hypersaline conditions within the CCS may contribute to the low diversity and abundance of fish, mobile invertebrates, and benthic macroinvertebrates. Warmer water temperatures and hypersaline conditions can have negative effects on benthic macroinvertebrate populations, so it was not unexpected that the CCS would have poorly established benthic macroinvertebrate communities (Lamptey & Armah, 2008). The absence of SAV found during the study is likely due to the poor water clarity within the CCS (Indian River Lagoon 2011 Consortium, 2015). Materials and Methods Sampling stations were established for water quality, fish and mobile invertebrate, SAV, and benthic macroinvertebrate sampling. An FPL airboat was used to access the stations and conduct the sampling program. Physical Parameters and Water Quality Data At each sampling station, meteorological data, including air temperature, wind speed and direction, and sky conditions, were recorded. Water depth at each station was measured using a marked measurement pole CCS Biological Characterization Study12 at shallow stations and a handheld sonar device at deeper stations. A Hach Hydrolab Quanta (Hach) water quality meter was used to measure water quality in situ at mid-depth for each sampling station during fish trap deployment and retrieval. Monitored variables included temperature (°C), specific conductance (milliSiemens per centimeter [mS/cm], converted to microSiemens per centimeter [µS/cm] for reporting purposes), salinity (Practical Salinity Units [PSU]), dissolved oxygen (DO) (milligrams per liter [mg/L]), and pH. Salinity was calculated (not measured directly) by the water quality meter using specific conductance and a temperature correction normalized to 15 °C (PSS-78 scale). Water clarity (in feet) was determined using a secchi disk. The (Hach) water quality meter used during sampling was calibrated following FDEP SOP-001/01 protocols for temperature, specific conductance (which calculates for salinity), DO, and pH. Meter calibration was performed prior to use and immediately following the final day of sampling. The required continuing calibration verification was performed between the first and second day of sampling to ensure that the meter was still within acceptable limits for all parameters. The water quality meter was within the FDEP acceptable criteria during the initial calibration, continuing calibration verification, and final calibration. Submerged Aquatic Vegetation Surveys Video surveys were conducted at all 10 sampling stations to qualitatively assess SAV coverage. SAV transects were 150-feet in length and shore-parallel near each sampling station. The starting point of each transect was located no more than 350 feet from the specific station location where water quality, cast net, fish trap, and benthic macroinvertebrate sampling occurred. A video camera was deployed over the side of the airboat and the bottom was examined for presence and relative abundance of seagrass every 10 feet along the 150-foot transect. Cast Net Sampling At each station, a 3/8-inch mesh, 10-foot radius (20-foot diameter) cast net was used to sample fish and invertebrates throughout the water column. A single cast net throw was made at each station; the throw was deemed valid if the net deployed to cover >70% of the possible net surface area coverage. If multiple casts were required to meet the net opening criteria, each subsequent cast was thrown in a new area at least 25 feet away from previous cast sites. Captured fish were either processed in the field when time permitted and released, or returned to the EAI laboratory for processing. Fish captured by the cast net were identified to species and measured, both Standard Length (SL) and Total Length (TL) were recorded. A maximum of 30 haphazardly-selected individuals were measured; all additional fish of the same species were counted, but not measured. Cast net sampling occurred on December 5, 2016. Sampling went without incident and repeat casts were rare, except at Station 7. This station had a jagged rock substrate which repeatedly snagged the net in the center of the canal, and tree debris which snagged the net at the edges of the canal. Net performance was most successful at sites with smooth sand or mud substrates. Fish Trap Sampling Minnow traps were deployed to capture cryptic fish and mobile invertebrates not sampled adequately by the cast net. The minnow traps were collapsible, umbrella-style hexagonal traps with 1/8-inch nylon mesh and 12 entry holes. At each sampling station, one surface and one benthic minnow trap was deployed CCS Biological Characterization Study13 simultaneously and allowed to soak for 23-25 hours before retrieval (Figure 7). Minnow traps were baited with white bread, cut clams, and cigar minnows torn in half. The bait types were chosen to lure species with different feeding preferences into the traps. Two 6-inch foam floats were used to float the surface fish traps and approximately two pounds of lead ingot were placed inside the benthic minnow traps to anchor them to the bottom. The surface and benthic minnow traps at each station were tethered together using a small rope, and were then attached to a secondary safety line with a weight and floating marker. Captured fish were either processed in the field when time permitted and released, or returned to the EAI laboratory for processing. Fish captured by the minnow traps were identified to species and a maximum of 30 haphazardly-selected individuals were measured (SL and TL); all additional fish of the same species were counted, but not measured. Crabs captured in the traps were identified to species, and Carapace Length (CL) and Carapace Width (CW) were recorded. Two traps were crushed by the airboat during retrieval, but despite the damage to the minnow trap frame, no mesh was torn and all organisms trapped were retrieved successfully. Benthic Macroinvertebrate Community Three replicate benthic samples were collected at each station using a mini-ponar grab sampler with a surface area of 225 square centimeters (cm²). Each sample was sieved through a 0.500 mm mesh screen and retained material was field preserved with a 10% formalin and rose bengal stain solution. Preserved samples were transported to the EAI laboratory for processing and taxonomic identification. Benthic macroinvertebrates were enumerated and identified to lowest practicable taxon. The benthic community structure at each station were characterized by abundance (total number of individuals), density (number of individuals/m²), species richness (total taxa), Shannon-Weiner Diversity Index (H'), and Pielou's Evenness (J'). The Shannon-Weiner Diversity Index was computed using logarithmic base
- e. Evenness was calculated by dividing sample diversity by the maximum diversity possible given the number of taxa present. Values range from 0 to 1, with 1 representing a community with individual specimens distributed evenly among species and low values representing communities dominated by a few species.
