3.0 RESULTS Although ichthyoplankton were sampled from September 2008 through August 2009, fish larvae were found in samples only from March through August (Table 3-1, Appendix Table 1). No fish eggs were collected in any samples, presumably because all resident species have demersal and adhesive eggs that would not normally be found in the water column. Prior to the first appearance of fish larvae in samples, a YOY catfish was captured in September 2008 and a YOY threadfin shad was captured in December 2008. Fish larvae first appeared in March 2009 samples and peaked in density in May at 125.15 organisms/100 m 3 (Figure 3-1). After this peak, density decreased rapidly to 0.41/100 m 3 in August (Figure 3-1).In March, threadfin shad YSL were numerically dominant (21.76/100 in 3), but small numbers of white perch, true percids (yellow perch and darters), and black crappie larvae were present. In April, substantial numbers of both YSL (17.97/100 m 3) and PYSL (14.72/100 M 3) threadfin shad were collected as the YSL larvae from March matured into PYSL. White perch YSL (15.55/100 M 3) and PYSL (7.41/100 M 3) increased in abundance in April. By May, most threadfin shad larvae had developed into PYSL (98.27/100 M 3) but some YSL were still present (17.91/100 M 3). Densities of YSL (0.46/100 in 3)and PYSL (3.46/100 in 3) white perch decreased from their monthly high in April. In June, PYSL clupeids (28.00/100 M 3) were dominant and total density of fish larvae was markedly lower, approximately 25% of the total density in May. PYSL Lepomis sp. (1.42/100 M 3) and PYSL clupeids (1.35/100 M 3) were predominant in July. By August, total density of fish larvae was very low and only yearling blue catfish (0.21/100 M 3) and PYSL Lepomis sp. (0.2 1/100 M 3) and clupeids (0.20/100 M 3) were present.For the 12-month sampling period, PYSL and YSL threadfin shad had the highest density and together with undetermined-stage threadfin shad composed approximately 71% of the total catch (Table 3-2).

1.0 INTRODUCTION
Ichthyoplankton (fish eggs and larvae) samples were collected in Monticello Reservoir to provide estimates of entrainment of ichthyoplankton at the proposed V.C. Summer Nuclear Station Units 2 and 3 Raw Water Intake Structure.
Although both units would use closed-cycle cooling (mechanical draft cooling towers), evaporative losses would require withdrawal of makeup water from Monticello Reservoir.
Makeup water withdrawal rates would be 36,214 gpm (137.08 m 3/min) under typical operating conditions and 58,800 gpm (222.58 m 3/min) under maximum operating conditions.
The purpose of this study was to collect ichthyoplankton data from Monticello Reservoir to estimate the number of ichthyoplankton potentially lost due to withdrawal of make-up water.2.0 METHODS AND MATERIALS Ichthyoplankton samples were collected at two parallel transects in the vicinity of the proposed intake (Figure 2-1) using 0.5 m-diameter, 0.300 mm-mesh bongo nets fitted with calibrated flowmeters (Figure 2-2). Tow length was about 250 m and each side of the bongo net filtered at least 50 M 3.The two sides of the bongo net were composited in the field, resulting in samples that ranged in volume from 105 to 191 M 3.Samples were preserved in the field with 5% formalin (Figure 2-3). Sampling started in September 2008 and continued for 12 consecutive months. Samples were collected once per month from September 2008 through February 2009, twice per month from March through July 2009, and once in August 2009 for a total of 17 sampling events (Table 2-1). This sampling regime was designed to reflect the reproductive behavior of resident fish species, all of which spawn in the spring and early summer.During each sampling event, samples were collected at the surface and mid depth during both the day and night for a total of 68 samples collected during the study.Additional information collected during sampling included surface, mid-depth, and near bottom water temperature
(°C) and dissolved oxygen concentration (mg/1), air temperature
(°C), and weather conditions
(% cloud cover, precipitation, wind speed and direction, and wave height) (Figure 2-4).Samples were forwarded to Normandeau Associates' biological laboratory where ichthyoplankton were identified to the lowest practical taxon, usually species, and enumerated as to lifestage:
egg, yolk-sac larvae (YSL), post yolk-sac larvae (PYSL), young of the year (YOY), and yearling (age 1) (Figure 2-5). No eggs were found in any samples and subsampling was not required for any species or lifestage.
Data were standardized to no./100 m 3 of water sampled. Since the proposed Raw Water Intake Structure will withdraw from all depths and operate 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> per day, monthly mean ichthyoplankton densities and 95% confidence intervals were calculated across depth and diel samples collected each month to provide water column and time-integrated estimate of densities.
To estimate potential entrainment of ichthyoplankton on a monthly basis, monthly mean densities and their upper and lower 95% confidence limits (no./100 in 3) were multiplied by the estimated monthly water withdrawal rates (typical:
137.08 m 3/min; maximum: 222.58 m 3/min). These monthly estimates were then summed to provide annual estimates of entrainment under the two proposed water withdrawal rates. Although YOY and yearling fish (Figure 2-6) were sometimes captured in the nets, which were towed at about 3 ft/sec, it is unlikely that they would be entrained at the proposed Raw Water Intake which would have a through-screen velocity of 0.5 ft/sec. These fish are included in data tables where the entire catch is presented but 21448.001 Summer Station Ichthyo Report.doc 9/28/09 I Normandeau Associates, Inc.
MONTICELLO RESERVOIR ICHTHYOPLANKTON STUDIES SEPTEMBER 2008- AUGUST 2009 excluded from analyses of ichthyoplankton density and percent composition because they are not part of the ichthyoplankton community.
Furthermore, YOY and yearling fish in most cases would be too large to be entrained through the proposed screens which will have 3/8-inch perforations.
3.0 RESULTS
Although ichthyoplankton were sampled from September 2008 through August 2009, fish larvae were found in samples only from March through August (Table 3-1, Appendix Table 1). No fish eggs were collected in any samples, presumably because all resident species have demersal and adhesive eggs that would not normally be found in the water column. Prior to the first appearance of fish larvae in samples, a YOY catfish was captured in September 2008 and a YOY threadfin shad was captured in December 2008. Fish larvae first appeared in March 2009 samples and peaked in density in May at 125.15 organisms/100 m 3 (Figure 3-1). After this peak, density decreased rapidly to 0.41/100 m 3 in August (Figure 3-1).In March, threadfin shad YSL were numerically dominant (21.76/100 in 3), but small numbers of white perch, true percids (yellow perch and darters), and black crappie larvae were present. In April, substantial numbers of both YSL (17.97/100 m 3) and PYSL (14.72/100 M 3) threadfin shad were collected as the YSL larvae from March matured into PYSL. White perch YSL (15.55/100 M 3) and PYSL (7.41/100 M 3) increased in abundance in April. By May, most threadfin shad larvae had developed into PYSL (98.27/100 M 3) but some YSL were still present (17.91/100 M 3). Densities of YSL (0.46/100 in 3)and PYSL (3.46/100 in 3) white perch decreased from their monthly high in April. In June, PYSL clupeids (28.00/100 M 3) were dominant and total density of fish larvae was markedly lower, approximately 25% of the total density in May. PYSL Lepomis sp. (1.42/100 M 3) and PYSL clupeids (1.35/100 M 3) were predominant in July. By August, total density of fish larvae was very low and only yearling blue catfish (0.21/100 M 3) and PYSL Lepomis sp. (0.2 1/100 M 3) and clupeids (0.20/100 M 3) were present.For the 12-month sampling period, PYSL and YSL threadfin shad had the highest density and together with undetermined-stage threadfin shad composed approximately 71% of the total catch (Table 3-2). White perch larvae were next in abundance with YSL and PYSL lifestages making up approximately 13% of the catch. The family Clupeidae, which was most likely a combination of threadfin shad and gizzard shad larvae, made up approximately 12% of the catch. All other species and lifestages combined made up less than 4% of the catch.Estimates of potential entrainment were developed by multiplying ichthyoplankton densities by estimated monthly water withdrawal rates (typical:
137.08 m 3/min; maximum: 222.58 m 3/min). An estimated 15.3 million larvae would be entrained annually under the typical water withdrawal rate and 24.9 million under the maximum water withdrawal rate (Table 3-3, Appendix Table 2), based on 2008-2009 densities.
The monthly pattern and species composition of entrainment estimates mirrored the monthly patterns in larval density (Figure 3-1) because the estimates are the product of larval densities and a constant (the two water withdrawal rates). Entrainment is expected to be very low in the fall and winter (September through February), begin to increase in March, reach a peak in May, and decrease rapidly through August (Appendix Table 2).Entrainment estimates were highest for threadfin shad larvae, which made up 71% of all larvae potentially entrained, under typical (10.9 million larvae) and maximum (17.6 million larvae) water withdrawal rate scenarios (Table 3-3). White perch entrainment estimates ranked second under typical 21448.001 Summer Station Ichthyo Report.doc 9/28/09 2 Normandeau Associates, Inc.
MONTICELLO RESERVOIR ICHTHYOPLANKTON STUDIES SEPTEMBER 2008 -AUGUST 2009 (1.9 million larvae) and maximum (3.1 million larvae) water withdrawal rates. White perch larvae made up 13% of the total entrainment estimate.
Clupeids were the third most abundant species potentially entrained under typical (1.8 million) and maximum water withdrawal rates (2.9 million).
Clupeids were 12% of the total entrainment estimate.Appendix Table 3 presents the water quality information collected during the ichthyoplankton study. As expected, temperature and DO levels had an inverse relationship due to the higher saturation levels of DO in colder water. DO levels were consistently highest in January (11. 1-11.3 mg/1) when water temperatures were among the lowest (10.6-12.2
'C). Conversely, the lowest DO levels (3.3-3.9 mg/1) occurred in August and September when water temperatures were greater than 27.0 'C. There was a general trend of decreasing DO levels with increasing depth. Appendix Table 4 presents the environmental conditions during sampling.
All environmental parameters were within ranges that allowed collection of valid ichthyoplankton samples.4.0 DiSCUSSION Threadfin shad and gizzard shad, members of the family Clupeidae, together made up approximately 73% of all the larvae collected in Monticello Reservoir and the same percentage of the entrainment estimate.
The category Clupeidae probably included only threadfin shad and gizzard shad, as no other clupeids are known to occur in Monticello Reservoir.
Blueback herring have been reported from the Broad River, but these alleged occurrences have been described as "perplexing" (Rohde et al. 2009)and "questionable" (Bettinger et al. 2003) by authorities on South Carolina's fishes. Assuming all the clupeid larvae were threadfin and gizzard shad, these two species made up 85% of all the larvae collected and the entrainment estimate.
Both threadfin and gizzard shad are important prey species in southern reservoirs and often contribute the most to fish biomass (Allen and DeVries 1993). Threadfin shad normally reach sexual maturity as yearlings.
Threadfin shad may spawn once or several times over a spawning season, with fecundity (number of eggs per ovary) ranging from 800 to 21,000, depending on age and size of the female (Johnson 1971; Jenkins and Burkhead 1994). Gizzard shad typically mature at age 2 or 3. Each female produces 22,400 to 543,900 eggs (Jenkins and Burkhead 1994), depending on age and size, with some studies showing declining fecundity in older fish (Williamson and Nelson 1985).Both species spawn in the spring when water temperature is greater than 15 'C, but gizzard shad usually spawn slightly earlier (Netsch et al. 1971). Both species use shallow water habitats for spawning, but threadfin shad tend to spawn near the surface while gizzard shad tend to spawn near the bottom (Shelton et al. 1982). Larval threadfin shad tend to move offshore and larval gizzard shad remain evenly distributed within 50 m of shore (Allen and DeVries 1993). After the larval stage both species are important prey species, but gizzard shad quickly grow to be too large to be consumed by most predators (Noble 1981). Therefore, threadfin shad is more valuable as a prey species.White perch were the next most abundant larvae, accounting for 13% of both the larvae collected and the entrainment estimate.
The white perch is a semi-anadromous species, native to Atlantic Coast estuaries, but has been established in many freshwater lakes and impoundments.
They have apparently been introduced to the Santee River watershed and Monticello Reservoir (Rohde et al. 2009; Warren et al.2000). Female white perch mature at age 3 or 4, and may produce from 20,000 to 150,000 eggs (Jenkins and Burkhead 1994). White perch spawn in the spring over sand and gravel substrates and there is evidence that reservoir populations may migrate to shallower water to spawn (Rohde et al. 2009). White 21448.001 Summer Station Ichthyo Report.doc 9/28/09 3 Normandeau Associates, Inc.
MONTICELLO RESERVOIR ICHTHYOPLANKTON STUDIES SEPTEMBER 2008 -AUGUST 2009 perch are important recreational fish through much of their native range; however, when stocked in reservoirs they can become stunted and compete with native fish.Dames and Moore (1985) conducted an ichthyoplankton study in Monticello Reservoir in 1983-1984 as part of the original 316(b) demonstration for V.C. Summer Station. In their study, total larval density was 53.9 larvae/100 m 3 at the surface and 11.8 larvae/100 m 3 at mid-depth at a station that was a short distance from our sampling stations.
At both depths combined, gizzard shad (61.9/100 in 3; 94%)were the dominant larval species and white bass ranked second in abundance (3.1/100 M 3; 5%). These densities are higher than those observed in the current study and threadfin shad, the dominant species in this study, was not observed.Reservoirs in the southeastern United States are generally most productive in the first several years after impoundment, as topsoils containing agricultural fertilizers and decaying organic matter are inundated by the rising waters of the reservoir.
After this initial burst of productivity, these reservoirs tend to show a decline as nutrients are depleted and sedimentation effectively seals the reservoir bottom.With increasing age, reservoirs depend more and more on nutrients brought in by inflowing riverwater, levels of which may vary seasonally and annually depending on weather and the degree of watershed development.
It's unclear if the apparent decline in Monticello Reservoir ichthyoplankton densities observed between the 1983-1984 study (Dames and Moore 1985) and the current study is related to lower reservoir productivity or is a reflection of normal biological variability.
Spawning success and survival of larval threadfin and gizzard shad (which dominated larval fish collections) are unpredictable and influenced by an array of density-dependent (intra-specific and inter-specific competition, predation) and density-independent (weather, which determines temperatures and rainfall patterns) factors that are outside of the scope of this study.Based on the current study, an estimated 15.3 million fish larvae would be entrained under typical operating conditions with 95% confidence limits of 2.2 million and 30.8 million. These confidence limits vary by a factor of about 15 and reflect seasonal variability.
Annual variability is demonstrated by the differing results between the current study and the Dames and Moore (1985) study which reported ichthyoplankton densities an order of magnitude greater. Furthermore, threadfin shad, the dominant larval species in the current study was not reported by Dames and Moore (1985). The ichthyoplankton community of Monticello reservoir is dominated by very few species and therefore is potentially subject to high variability.
A complete or partial failure to spawn by a dominant species such as either threadfin shad or white perch due to natural causes would result in low ichthyoplankton density and a similar reduction in potential entrainment.
Considering the dynamic nature of the fish community in Monticello Reservoir, especially the possibility of further introductions, of non-native fish such as white perch, large variations in ichthyoplankton density and potential entrainment is to be expected.5.0 LITERATURE CITED Allen, M.S. and D.R.
