Tampa Electric Company is presently operating four coal -fired 

electric generating units at Big Bend Power Station. The site is located 

on the eastern shore of Tampa Bay in North - Ruskin, Florida. All four 

units utilize once-through cooling systems; each unit circulates approximately 537 cfs of water. The four units draw water from a single 

intake canal and release heated water to the Bay via a single discharge 

canal. To reduce entrainment at the plant, Units 3 and 4 were fitted 

with fine mesh screens (0.5 mm); screened organisms were returned to the 

Apollo Beach northern embayment. 

In fulfillment of the Clean Water Act, an NPDES permit was 

obtained by Tampa Electric Company to construct and operate Unit 4. A 

316 Demonstration (a) and (b) Biological Monitoring Program was conducted by Tampa Electric Company in accordance with conditions of the 

NPDES Permit (No. FL 0000817) and the State of Florida Power Plant Site 

Certification (Application No. P.A. 79-12; Case No. 80-1723). The 

general requirements of the program are summarized in the Final Environmental Impact Statement for Tampa Electric Company, Big Bend Unit 4 

(pages 4-64 through 4-66). 

Studies conducted by Mote Marine Laboratory (MML) during 1980 on 

the prototype fine mesh.screen intake structure at the site demonstrated 

that 0.5 mm mesh screens were effective in screening a majority (>80%) of 

meroplankton at the site. Studies during 1985-86 on the actual fine mesh 

screen system showed that sampling methodology was not adequate to 

determine accurate screening efficiencies. All six screens are now in 

optimum operational condition and sampling methodology has been stream1 ined for maximum efficiency. 

An approved scope of work was submitted to both the Environmental 

Protection Agency and the Department of Environmental Regulation on 

March 16, 1987. The objective of this Fine Mesh Screen (FMS) Optimization Study is to evaluate the efficiency of the screens in retaining 

organisms during the 1987 spawning season, with emphasis placed on 

obtaining data for the following representative important species (RIS):

2.0 METHODOLOGY 

SampJing was conducted from both the intake canal (boat) and the 

fine mesh screen platform at the Big Bend Station (Figures 1 and 2). Six 

replicate pump samples were collected from behind screen 3A (designated 

as B-3A), along with six replicate pump samples from in front of both 

sides of screen 3A (designated as 3A-West and 3A-East). This was the 

designated test screen and comprised the samples which were processed at 

MML. Previous engineering studies conducted by Tampa Electric Company 

determined that the flow of water was approximately equal across all six 

screens; therefore, screen 3A was sampled to provide representative 

information that can be applied to all six screens. In addition, three 

replicate pump samples were collected from behind each of the remaining 

five screens (designated as B-3B, B-3C, B-44 B-4B, and B-4C) as back-up 

samples in the event sampling appeared inadequate at screen 3A. The fine 

mesh screen deck arrangement, along with the location of the testing 

equipment, is provided in Figure 2. Pumps were run for 30 minutes and 

sampled three water levels (surface, middle, and bottom) 10 minutes at 

each level. The flows from each pump were channeled into the intake 

screenwell located behind the screens, where the water from each screen

location was pumped into a corresponding 0.505 mm ichthyoplankton net. A 

series of oblique meroplankton tows (six rep1 icates) was also collected 

in the intake canal by boat during each set of samples. Total number of 

samples collected during each sampling episode is as follows: 

6 replicates x 3 pumps x 3 times (B-3A, 3A-West, 3A-East) = 54 

3 replicates x 5 pumps x 3 times (3B, 3C, 4A, 48, 4C) = 45 

6 replicates x 3 times (intake canal) = 18 

Total number of samples/event = 117 

Only the 54 samples collected from front and behind screen of 3A 

were processed during each sampling period. All other samples were 

archived. Information from samples collected from both in front of and 

behind screen 3A provides the basis for the evaluation of screening 

efficiency in this report. 

Samplings to date are provided below:

Asterisks (*) indicate samples which were processed at MML and upon which 

the results of this report are based. SamplGs collected from the 

remaining dates have been archived. A detailed description of laboratory 

procedures is provided in Appendix A. 

Each sampling event consisted of two day samplings (morning and 

afternoon) and one night sampling. Screening efficiencies were calcu- ' 

lated by dividing the values from the B-3A sample by the mean of the 3AWest and 3A-East samples. This provides the percentage of organisms

which were able to pass through screen 3A. Multiplying this number by 

100 then subtracting 100 provides screening efficiency. Screening 

efficiencies were calculated for each identified species, as well as for 

total species at various life stages (eggs, prolarvae, etc.). 

3.0 RESULTS 

Mean densities of eggs, larvae (prolarvae and postlarvae), and 

invertebrates collected over the four sampling dates are shown in 

Figures 3, 4 and 5. Overall, a strong increase in numbers of organisms 

was observed over the 4 sampling periods. Total numbers of eggs from the 

first two samplings 13/18 and 3/31) were calculated to be 8311 and 994 

eggs per 100 cubic meters respectively, while these numbers increased to 

261,516 and 989,766 eggs per 100 cubic meters during the last two 

samplings (4/16 and 5/12). This is a clear indication of the onset of 

the spawning season. 

In general, numbers of organisms collected from behind screen 3A 

were markedly lower than those collected in front of the screens (3A-West 

or 3A-East). Because of the large variation in numbers of eggs between 

sampling dates, values had to be plotted on a semi log scale in Figures 3, 4 and 5; therefore, comparisons between samples from front and 

behind the screens appear more similar than actual data. All three sets 

of values showed the same overall trend through time, but numbers of 

organisms from behind screen. 3A were consistently and markedly lower 

overall. 

Table 1 presents the summarized results for both the RIS and other 

species collected in relatively high abundances. Many of the RIS 

organisms listed on page 1 were either not collected or collected in 

extremely low numbers during the study. This is consistent with the 

findings of previous studies at the site. Eggs were dominated by 

Sciaenidae spp. and Anchoa rnitchilli. Both of these species were 

screened effectively overall, with mean losses of only 2.8% and 8.3%, 

respectively. Anchoa mitchilli was also the only larval RIS col7ected in 

high abundances. This life stage was also screened effectively, with a 

mean loss of only 11.2%. Other larval RIS (Bairdiella chrvsoura and

Cynoscion nebulosus) were collected less frequently and did not occur in 

any samples behind screen 3A; consequently screening losses for these 

species are 0. Test results for two important invertebrate species 

(MeniDDe mercenaria and Penaeus spp.) indicate losses are nearly 0 for 

these organisms. Finally, three other larval species collected in high 

abundance (Blenniidae spp., Gobiidae spp., and Gobiesox strumosus) show 

somewhat greater losses and higher variability. The lower efficiencies 

for these groups of fishes may be due in part to their habitat requirements. They are demersal fishes, living on or very near the bottom and 

utilizing pilings, rock, or dead shell material as habitat, similar to 

that found in the screenwell. The relatively high numbers of these taxa 

which were found behind screen 3A-rnay represent (at least in part) an 

established population of these fishes which are currently 1 iving behind 

the screens. 

A complete listing of all species collected during the four 

sampling periods, along with their mean densities and calculated screening efficiencies for each time and date, are provided in Appendix 6, 

Screening efficiencies for eggs remained consistently high for 11 out of 

12 samplings, with values greater than 95% for 10 out of 12 samplings. A 

single lower value of 66.01% occurred during the Day 2 sampling on 

4/16/87. In general, larvae were effectively screened, with efficiencies 

ranging from 71.47% to 98.57%. A1 though numbers of invertebrates 

collected were low, data collected for invertebrates shows virtually 100% 

effectiveness in screening of selected important invertebrates. 

4.0 SUMMARY 

Based on the data collected and analyzed during this study, the 

1. The FMS system is functioning effectively in the screening of 

meroplankton in general, with consistently high screening efficiencies observed through the majority of the samplings. 

2- The FMS system appears to be more effective in the screening of 

eggs than larvae, although both life stages maintained effic ;encies greater than 80% in general. 

following statements can be made: 
3. 

4. 

5. 

Eggs and larvae of the most abundant faunal groups collected during 

the study, anchovies and sciaenids, are effectively screened at 

all life stages, although there are isolated occurrences of lower 

screening efficiencies. 

Other common groups encountered, such as the Families Blenniidae 

and Gobiidae, exhibit lower screen efficiency most likely- related 

to the spawning of established populations of these groups behind 

the screens. 

The FMS system is effective in the screening of important 

invertebrate species. 

5.0 CONCLUSION 

I Overall, the FMS sys’tern is effectively screening R7S organisms 

and life stages that were collected at Big Bend.

Samples were preserved in 10% buffered formal in for subsequent 

1 aboratory analysis of meroplankton. 

Samples were processed at MML in a manner so that each sample or 

subsample was traceable to its collection, and all data reported for 

these portions of the study were both valid and documented. Procedures 

were as follows: 

1. Each aliquot was examined twice, with agitation between 

examinations. To check for identification efficiency, all 

samples were reanalyzed arid verified by a qualified 

individual other than the person who conducted the initial 

sorting and identification. 

2. Identification of larval specimens was made through the use 

of standard literature sources for each RIS. A reference 

collection of taxonomically confirmed species was 

maintained. 

3. Subsampling was accomplished by use of a 10 m'l Tipet 

dispenser or 5 ml pipet for numerous eggs. The sample was 

placed in an appropriately sized Erlenmeyer flask after the 

volume was adjusted to allow efficient sorting. The sample 

was agitated thoroughly, and aliquots were drawn off into a 

gridded petri dish. Depending on the density of plankton, 

up to four aliquots were sorted at one time. 

4. Samples which contained a high density of Anchoa spp. 

postlarvae were split to allow for more efficient sorting. 

Initial and rinse volumes were placed into a plankton 

splitter and .separated into a usable volume. This portion 

of the sample was sorted as above. The remainder of the 

sample was sorted for all other species and life stages.

5. Bench sheets contained all field data for a sample as well 

as sorting data. Two copies of the bench sheets were made. 

The original and one copy were retained by the project 

coordinator, and one copy was placed in the section 

supervisor's files. Data was transferred to computer for 

analysis after final identifications. 

6. All samples were sorted in 100% formalin until the project 

was completed. All sorted specimens were catalogued and 

similarly maintained, except for voucher specimens,: which 

were placed in the permanent MML reference collection. 

Catalog numbers of sorted specimens were written on the 

data bench sheets and in a bound notebook in which entries 

were logged as the samples were sorted.
