Abstract
Reproductive cycle, gonadosomatic index(GSI), egg diameter composition, first sexual maturity, sexually matured length(50% of first sexual maturity), and sex ratio of Amusium japonicum japonicum, were investigated by histological observations and morphometric data. Samples were collected monthly from the subtidal zone of Sogwipo, Jejudo, Korea, for two years. The sun and moon scallop Amusium japonicum japonicum is dioecious. Monthly variation in the GSI showed similar patterns with the reproductive cycle. Ripe oocytes were about
한국 제주도산 해가리비(Amusium japonicum japonicum)를 대상으로 생식주기, 생식소중량지수(GSI), 난경조성 변화, 군성숙도, 성적 성숙체장(50% 군성숙도) 및 성비를 조직학적 관찰 및 생체 측정에 의해 조사하였다. 해가리비는 자웅이체이다. 생식소 중량지수(GSI)의 월별 변화는 생식주기와 유사한 양상을 보였다. 완숙 난모세포들은 직경이 약
