Abstract
Reproductive cycle and sex ratio of the marsh clam Corbicula japonica, a oviparous clam, were investigated monthly by histological observation. Samples were collected in brackish water of Namdae stream on the east coast of Korea from November 2000 to October 2001. It was able to devide the reproductive cycle of this species into five successive stages; early active (April to June), late active (May to June), ripe (June to August), partially spawned (June to September), spent (September to January) and resting stage (February to April). The spawning period was from July to September, and the main spawning occurred between August and September when seawater temperatures reached above 26
동해 중부 해안 하천에 서식하는 기수산 재첩의 자원관리와 인공종묘 생산을 위한 생식생물학적 조사를 위해 2000년 11월부터 2001년 10월까지 강원도 양양군 소재 남대천 하구에서 매월 30-40 개체씩 채집하여 성장, 생식소지수, 배우자 형성과정 및 생식주기, 성비 등을 조사하였다. 강원도 일본재첩은 자웅이체 난생종으로 암컷의 생식소는 회흑색, 수컷의 생식소는 유백색을 띄어 육안적으로 86% 이상의 구별가능성을 보였다. 성숙한 난모세포는 약 80
