Abstract

Sexual maturation and gametogenic cycle of the hard shelled mussel, Mytilus coruscus were investigated by means of histological method. Specimens were collected monthly in Hansan Bay of south coast, Korea from January to December 2002. Sex of the clam was dioecious. The gonads are composed of a number of gametogenic follicles. The gonad index (GI) was reached the maximum in February (3.40), and the minimum in August (1.18). The monthly variation of condition index (CI) coincides with gonad index. The main spawning occurs between February and March. The gametogenic cycle of the clam could be divided into six stages: resting (August to November), multiplicative (November to December), growing (December to January), maturation (January to February), partially spent (February to April) and completely spent/degenerative stage (April to July). Sex ratio (♀/♂) was 1:0.96.

2000년 1월부터 12월까지 남해안 한산만 해역에서 채집한 홍합의 생식소 발달과 생식주기에 관하여 조직학적 방법을 이용하여 조사하였다. 홍합은 자웅이체이며, 생식소는 암 수 모두 다수의 배우자형성소낭으로 이루어져 있었다. 생식소지수(GI)는 2월(3.40)에 가장 높았으며, 8월(1.18)에 가장 낮았다. 비만도(CI)는 생식소지수(GI)와 유사하게 변화하였다. 홍합의 주 산란기는 2∼3월이며, 생식주기는 휴지기(8∼11월), 분열증식기(11∼12월), 성장기(12∼1월), 성숙기(1∼2월), 부분방출기(2∼4월), 완전방출 및 퇴화흡수기(4∼7월)로 구분할 수 있었다. 성비(암:수)는 1:0.96으로 조사되었다.
