1 WOCDBORER STUDY ASSOCIATED WITH THE OYSTER CREEK GENERATING STATION by N.J. Maciolek, C.I. Belmore, and R.E. Hillman INTRODUCTION 1he William F. Clapp Laboratories of Batte11e's Columbus Laboratories is conducting an investigation to determine whether the generating station is -

affecting 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 Annual Report on Woodborer Study Associated with the Oyster Creek Generating Station, Report 14968, dated February 29, 1980.

This report presents the sum =ary data for the twentieth quarterly period from February 9, 1980 through May 10, 1980.

PROCEDURES AND INTERIM DATA Exposure Panels The long-term and short-term exposure panels were retrieved and re-placed 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 March 3-4, 1980, April 7-9, 1980, and May 8-10, 1980. Long-term and short-term panels at all stations were retrieved and replaced. At Station 16 in April, the rack was found out of the water, and was resubmerged.

Table 1 describes the geographical locations of the exposure sites.

The summary data for the laboratory examination of the panels may be found in l l

Tables 2 through 5.

Water Quality-Salinity, water temperature, dissolved oxygen, and pH were deter-mined with a Hydrolab (Model II B). The results for March, April, and May, 1980 may be found in Tables 6 through 8.

Teredinid Gonadal Development Studies Table 9 shows the gonad condition of the teredinid borers collected from 'l ebruary through April,1980. Included are results from special long-term panels exposed for periods ranging from 12 to 18 months.
