WOODBORER STUDY ASSOCIATED WITH THE OYSTER CREEK CENERATING STATION by B.R. Richards, C.I. Belmore, and R.E. Hillman INTRODUCTION The William F. Clapp Laboratories of Battelle's Columbus Laboratories is conducting an investigation to determine whether the generating station is af fecting the resident marine borer population in Oyster Creek to the extent that that population is contributing significantly to marine borer-caused damage in Barnegat Bay.

A description of the program and procedures used may be found in the First Quarterly Report on Woodborer Study Associated with the Oyster Creek Generating StatLon, Report No. 14647, dated October 31, 1975, with the exception that the marine borer larvae program was discontinued in November, 1977.

This report presents the summary data for the thirteenth I quarterly period from May 4, 1978, through August 10, 1978.

PROCEDURES AND INTERIM DATA Exposure Panels The long-term and short-term exposure panels were retrieved and replaced with new untreated pre-soaked (for two weeks) panels at I the 20 exposure sites in Barnegal Bay and adjacent waters (Figure 1) during the weeks of June 1-2, July 10-13, and August 7-10, 1978. The rack at Site 13, Cedar Creek was missing in July. It was located in August and two long-term panels were removed and replaced in order to maintain the proper panel sequence.

Table 1 describes the geographical locations of the exposure sites. The summary data for the laboratory examination of the panels may be found in Tables 2 through 5.

Water Quality Salinity, water temperature, dissolved oxygen, and pH were determined with a Hydrolab (Model II B). The results for June, July, and August may be found in Tables 6 through 8.

In July the water at the sites in Stouts Creek and Forked River ucar Teds Marina had a dark discoleration, probably due to the I presence of humic material. The humic material is believed to be carried from the swamps down the creeks af ter heavy rains.

Teredinid Conadal Development Studies Table 9 shows the gonad condition of the teredinid borers collected from May through August, 1978. Included are results from special long-term panels exposed for a 12-month period.
