SUMMARY

l This progress report presents data from field and laboratory work during the period May 1 to July 31, 1984. Also included are the results of observations on gonad development in samples collected in April, May, and June,1984.

All field work during this quarter was carried out by GPU Nuclear personnel.

Temperature, salinity, dissolved oxygen and pH were measured and recorded at each of the 20 stations during the three periods of exposure panel exchange.

Teredinidae were found in the six-month exposure panel removed in May,1984 from the Coast Guard Station. Prior to 1983, no shipworms had ever been found in exposure panels removed in May or June from sites in Barnegat Bay.

For the most part, gonad development was in the early active stage through April and May, and into the late active phase in June. A notable exception was at Station 17, where many of the Teredo navalis specimens recovered in April were ripe to partially spawned. This was also true of June's sample. Otherwise, development patterns were normal for this time of year.

PROGRESS REPORT FOR THE THIRTY-SEVENTH QUARTER on STUDY OF WOODBORER POPULATIONS IN RELATION TO THE OYSTER CREEK NUCLEAR GENERATING STATION to GPU NUCLEAR CORPORATION August 31,1984 by Robert E. Hillman and CJ. Belmore I

REPORT NO.15245 May 1,1984 to July 31,1984 from BATTELLE New England Marine Research 1.aboratory Duxbury, Massachusetts 02332 INTRODUCTION Britelle's New England Marine Research Laboratory is conducting an investigation en determine whether the Oyster Creek Nuclear Generating Station is affec:ing the i uldent marine borer population in Oyster Creek to the extent that that population is co stributing significantly to marine borer-caused damage in Barnegat Bay.

A description of the program and procedures used may be found in the eighth

! annual report titled, " Study of Woodborer Populations in Relation to the Oyster Creek Generatind Station", dated May 15,1984.

2 This report presents data for the thirty-seventh quarterly period from May 1 to July 31,1984.

PROCEDURES AND INTERIM DATA l E==re panels The long-term and short-term exposure panels were retrieved and replaced with new untreated pre-soaked (for two weeks) panels at the 20 exposure sites in Barnegat Bay and adjacent waters (Figure 1) during the periods of May 14-15, June 18-12, and July 9-10, 1984. Long-term and short-term panels at all stations were retrieved and replaced by personnel from GPU's Oyster Creek Nuclear Generating Station.

Table 1 describes the geographical locations of the exposure sites. Data from the laboratory examination of the panels are presented in Tables 2 through 5.

Dater Quality Salinity, water temperature, dissolved oxygen and pH were taken at each site by the GPU Nuclear field team. Results for May, June, and July,1984 are presented in Tables 6 through 8.

Teredinid Gonadal Development Studies Table 9 shows the gonad condition of teredinid borers collected in April, May, and June,1984. Included are results from panels exposed for periods ranging from 6 to 12 months.
