초록
돌돔 Oplegnathus fasciatus의 인위적인 성 성숙 및 산란 유도를 위한 연구에서, 3년생 돌돔 친어를 대상으로 수온 및 광주기 조절에 의한 생식소 발달을 조직학적으로 조사하였다. 수온 및 광주기 조절구 (Exp. I)는 1996년 12월부터 1997년 2월까지 수온은
Artificial gonadal maturation and spawning inducement of striped knife-jaw Oplegnathus fasciatus were studied. Effects of water temperature and photoperiod under different regims on gonadal activity and maturation of three years old O. fasciatus were investigated histologically. In experiment I (Exp. I), water temperature was gradually increased from
