Abstract

Larval distribution of bivalve from 29 stations in Deukryang Bay was examined from May to November in 1995. The abundance of total larvae increased from May ($3,736\;inds/m^3$) and reached maximum in August ($174,616\;inds/m^3$). But it decreased continuously until November ($2,171\;inds/m^3$). D-shape, early umbone and advanced umbone stage larvae composed of 76%, 18% and 6%, respectively, of total bivalve larvae. Nine larval species of bivalve were identified in this study. The mean abundance of Scapharca subcrenata larvae was $14,030\;inds/m^3$, which was 33.5% of total identified larvae. S. broughtonii (16.2%), Crassostrea gigas (12.5%), Mytilus edulis (10.2%) were also major species in order of their abundance. Considering the monthly larval occurrence in Deukryang Bay, main spawning month of bivalves except M. edulis and M. senhausia was estimated as July. Even though the spatial distribution of bivalve larvae in Deukryang Bay was different by the species, the larvae were generally abundant in the inner and west area of the bay, where was shallower and higher water temperature than the entrance and east area of the bay.

득량만의 조개류 유생의 분포를 연구하기 위하여 1995년 5월부터 11월까지 만 전체에 29개의 정점에서 유생을 채집 조사하였다. 조개류 유생의 출현량(개체/$m^3$)은 5월(3,736 개체/$m^3$)부터 증가하여 8월(174,616 개체/$m^3$)에 최고에 이른 후 11월 (2,171 개체/$m^3$)까지 계속 감소하였다. 5월부터 11월까지 출현한 $1\;m^3$ 당 평균 총 유생 가운데 D상은 76%, 각정기 유생은 18%, 성숙 각정기 유생은 6%를 차지하였다. 5월부터 11월까지 득량만에서 동정된 9종의 조개류 유생 중 새고막은 14,030 개체/$m^3$로 전체 동정된 유생의 33.5%를 차지하였으며, 피조개(16.2%), 참굴(12.5%), 종밋(11.0%), 진주담치(10.2%)의 순이었다. 득량만 조개류의 유생 분포의 결과로 추정해 볼 때 진주담치와 종밋을 제외한 대부분 조개류의 주 산란시기는 7월 일 것으로 판단된다. 득량만 조개류 유생의 공간적인 분포는 종에 따라 차이를 보이나, 전체적으로 보면 만 입구에서는 출현량이 적고, 수심이 얕고 수온이 높은 만 안쪽과 서쪽 해역에서는 출현량이 많았다.
