SUMMARY

This progress report presents data from field and laboratory work carried out during the period November 1,1985 through January 31, 1986. Also included are the results of observations on gonad development in samples collected in October, November and December,1985.

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

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

The decline in the abundance of Bankia gouldi recovered from panels in Barnegat Bay continued through the present reporting perind. Only three specimens of Bankia gouldi were identified in the 6-month exposure panels examined during the period covered by this report.

Most of the shipworms collected in October were adults in the late active to spent phase of gonad development. By November, the shipworms from the late summer and early fall set had begun to mature, and most of the specimens recovered were juveniles with gonads primarily in the early active phase. This condition persisted into December, when it was arrested by the colder water. This has been the usual pattern throughout the study.

1 PROGRESS REPORT FOR THE FORTY-THIRD QUARTER on STUDY OF WOODBORER POPULATIONS IN RELATION TO THE OYSTER CREEK NUCLEAR GENERATING STATION to GPU NUCLEAR CORPORATION February 28,1986 by Robert E. Hillman and C.I. Belmore REPORT NO.15330 For the Period November 1,1985 to January 31,1986 from BATTELLE New England Marine Research Laboratory 397 Washington Street Duxbury, Massachusetts 02332 INTRODUCTION l Battelle New England Marine Research Laboratory is conducting an %

investigation to determine whether the Oyster Creek Nuclear Generating Station is affecting the resident marine borer population in Oyster Creek to the extent that the population is contributing significantly to marine borer-caused damage in Barnegat Bay, New Jersey.

A description of the program and procedures used may be found in the ninth annual report titled " Study of Woodborer Populations in Relation to the Oyster Creek Generating Station," dated May 15,1985.

This report presents data for the forty-third quarterly period from November 1,1985 to January 31,1986.

2 PROCEDURES AND INTERIM DATA Exposure Panels Personnel from GPU's Oyster Creek Nuclear Generating Station retrieved and replaced the long-term (6-month) and short-term (1-month) exposure panels with new untreated presoaked (for two weeks) panels at the 20 exposure sites in Barnegat Bay and adjacent waters (Figure 1) during the periods of November 11-12, December 9-10, 1985 and January 13-14, 1986.

Table I describes the geographical locations of the exposure sites. Data frorn I

the laboratory examination of the panels are presented in Tables 2 through 5.

The short-term panel removed from Station 10A in January had been incorrectly labeled "6" instead of "C." It had been placed in the proper position for the l

control (short-term) panel, however, and was retrieved as the short-term panel. The regular "6" panel was properly labeled, located and retrieved, so there was no effect on the data collection or analysis.

Over 99?6 of the specimens collected (5515 collected for the quarter) continue to come from Station 1. The abundance of Bankia gouldi has continued to decline, with only two specimens being collected in December (one each from Stations 11 and 13), and one in January (Station 10A).

Water Quality Salinity, water temperature, dissolved oxygen and pH were measured at each exposure panel site by the GPU Nuclear field team. Results' for November and December,1985, and January,1986 are presented in Tables 6 through 3. No unusual variations in water quality were noted during the report period.

j Teredinid Gonadal Development Studies Table 9 shows the gonad condition of teredinid borers collected in October, November, and December,1985. Included are results from the regular long- and short-term panels, as well as the 12-month panels originally established for pathology studies.

Most gonads from the October collections were in the late-active to spent phase typical of that month. By November, the juveniles that had set in late summer to early fall had begun to develop, and the early active phase predominated. This condition, arrested by the dropping water temperatures, persisted in those specimens collected in December.
