, '\ J INTRODUCITON The objective of this monthly report is to document compliance with the nonradiological (aquatic) environmental monitoring programs specified in Sections 3.1.la(4), 3.1.2a, and 4.6.1 of the Environmental Technical Specification (ETS). These programs are being carried out as directed in the Environmental Controls Aquatic Sampling Manual. Program elements being conducted under contract to GPU Nuclear Corporation include benthic macroinvertebrates, ichthyoplankton, fish population dynamics (seine and electrofishing), creel surveys, and water quality. The ultimate purpose of these studies is to obtain a database sufficient to establish the natural fluctuations within the ecosystem and identify any significant biological alterations resulting from the Three Mile Island Nuclear Station (TMINS).

l Compliance with all programs specified in the ETS and detailed in the Aquatic Sampling Manual was achieved in l

April 1988 (Table 1). Inclement weather resulted in changes to the TMINS Aquatic Sampling Schedule in April. Benthic macroinvertebrate sampling was rescheduled from 7 to 12 April due to rain and windy weather conditions.

Data presented herein are considered provisional, pending subsequent proofing, analysis, and presentation in the annual report. I 1 l 1

', , * \ v s' Benthic Macroinvertebrates Objective: To assess the abundance, distribution, and diversity of benthic macroinvertebrates at three j stations in the vicinity of TMINS.

1 Progresc: Replicate (4) macroinvertebrate samples were collected at each of the three stations on 12 April 1988 (Table 1). Sorting of the 12 April samples has been i

completed; identification of those samples is in progress.

Ichthyoplankton l l

Objective: To determine species composition, relative ,

I abundance, density, and seasonal and spatial distribution of ichthyoplankton at eight stations in the l vicinity of TMINS.

Progress: Repl'.cate (2) ichthyoplankton samples were taken at each of the eight stations on 5, 12, 19, and 26 April 1988 (Table 1). All samples collected through 26 April have been sorted; identification of the April ichthyoplankton has been initiated.

Objective: To assess species composition, relative '

abundance, seasonal and spatial distribution, condition:

factor,-occurrence of parasites, anomalies, and fish

~

kills, and species: diversity of fishes vulnerable to seine capture at six-stations in.the vicinity of TMINS.

l Erogress: Seine collections.were taken at each of the,  ;

i j Li:: stations on 20 April 1988'(Table 1). Processing of tne 20 April samples is about 70% complete.

Electrofishing l

Objective: To assess species composition, relative abundance, occurrence of parasites, anomalies, and species diversity of fishes vulnerable to electrofisher captured at six stations in the vicinity of TMINS.

l Progress: Electrofishing at the six zones was completed J on 13-14 April 1988 (Table 1). A total of 578 fish of 19 species was collected in April (Table 2). Most fish (214 specimens) were collected at Station 11B1; most species (12) were taken at Station 985. -The catch was dominated by the pumpkinseed, redbreast sunfish, and i smallmouth bass. Bluegill and walleye were also i

abundant. Ectoparasites and anomalies were observed on l 3

l i

. I

, si 64 fish; anchor worms (Lernaea) and leeches were most prevalent. Redbreast sunfish, pumpkinseed,.and bluegill were most commonly affected.

Creel Survey Objective: To investigate the extent and success of sportfishing, and determine angler residence and use of catch, in the Susquehanna River near TMINS.

Progress: Creel surveys were conducted on 8, 10, 23, and 28 April 1988 (Table 1). Interviews consisted of 332 ,

anglers who fished a total of 921.00 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />, caught 571 fish, and harvested 70 fish.(12.3% of the total catch)

(Tables 3 through 6). The average catch per effort (c/e) and harvest per effort were 0.62 and 0.08 per

hour, respectively. Smallmouth bass and walleye were the predominant species caught (290 and 161 specimens, respective.l.y). Fishing pressure was greatest in the '

General Reservoir with 221 anglers interviewed and a [

total of 761.75 hours8.680556e-4 days <br />0.0208 hours <br />1.240079e-4 weeks <br />2.85375e-5 months <br /> fished. Most fish were caught in the General Reservoir (184) but most were harvested (31) from the East Dam area. The highest catch per effort I l

l- (5.67) and harvest per effort (0.58) occurred at the l

West and East Dam areas, respectively. Anglers were i

predominantly residents of York or Dauphin counties and i

4 l

e

'1 1 the majority reported that they eat or would eat a portion of their catch.

Water Quality Analysis Objective: To measure select physical and chemical parameters of the Susquehanna River in the vicinity of TMINS concurrent with General Ecological Survey samples.

Progress: Water quality samples were collected on 12 April 1988 and forwarded to TMI-EC (Table 1). Selected water quality parameters were also measured at sampling times and locations described in the Aquatic Sampling Manual.
