SUMMARY
This progress report presents data from field and laboratory work during the period July 21,1983 to October 20,1983.
All field work during this quarter was carried out by GPU Nuclear personnel.
Temperature,calinity, dissolved oxygen and pH were measured and recorded at each of the 20 stations during the three periods of exposure panel exchange.
Shipworm damage has increased this year as compared with 1982, particularly at Stations 13 and 14. Bankia gouldi is responsible for the increase. One specimen of Bankia gouldi was found in the long-term exposure panel remove! from Station 17 in October,1983. The last time any Bankia were found in long-term exposure panels from this site was 1978. Teredo navalis continues to be active there also.
Two Limnoria tunnels were found in the long-term exposure panel from Station 5 at the mouth of Oyster Creek in September,1983. There were no tunnels in the panels examined from this site in October,1983.
No Teredo bartschi have been found in any of the exposure panels in Barnegat Bay as yet this year.
For the most part, the gonads of both B. gouldi and T. navalis were in typical mid-to late-summer condition, with most being in the late active to partially spawned stage. No unusual conditions were noted in the gonad histology.
2 PROGRESS REPORT FOR THE THIRTY-FOURTH QUARTER on STUDY OF WOODBORER POPULATIONS IN RELATION TO THE OYSTER CREEK GENERATING STATION to GPU NUCLEAR CORPORATION November 30,1983 by Robert E. Hillman and C.I. Belmore REPORT NO.15207 July 21,1983 to October 20,1983 from BATTELLE New England Marine Research Laboratory Duxbury, Massachusetts 02332 INTRODUCTION Battelle's New England Marine Research Laboratory is conducting an investigation to determine whether the generating station is affecting the resident ti;crine berer 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 seventh annual report titled, " Study of Woodborer Populations in Relation to the Oyster Creek Generating Station", dated May 15,1983.
This report presents data for the thirty-fourth quarterly period from July 21 to October 20,1983.
i 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 the 20 exposure sites in Barnegat Bay and adjacent waters (Figure 1) during the periods of August 1-2, September 6-7, and October 4-5, 1983. I.cag-term and short-term panels at 211 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 exarr.ination of the panels are presented in Tables 2 through 5.
Water Quality Salinity, water temperature, dissolved oxygen and pH were taken at each site by the GPU Nuclear field team. Results for August, September, and October,1983 are presented in Tables 6 through 8.
Teredinid Gonadal Development Studies Table 9 shows the gonad condition of teredinid borers collected in July, August, and September,1983. Included are results from panels exposed for periods ranging from 6 to 12 months.
