Abstract
Gonad structure, germ cell development and reproductive cycle of the smallmouth scorpionfish, Scorpaena miostoma were investigated based on histological method. Samples were collected monthly in the vicinity of Suyoung Bay, Pusan, Korea from November 1995 to October 1996. The testis is seminiferous tubule type in internal structure. Seminiferous tubule consists of numerous testicular cysts which contain numerous germ cells in same developmental stage. The ovary consists of several ovarian lamellae originated from ovarian outer membrane. Oogonia originated from the inner surface of the ovarian lamella protrude to the ovarian cavity in oocyte stage, and they are suspended by the egg stalk. Biological minimum size of female and male were 12.5cm in total length. Gonadosomatic index (GSI) of female (3.81) and male (0.23) were the highest in October. Reproductive cycle was classified into the following successive stages: in female, growing stage
1995년 11월부터 1996년 10월까지 부산 수영만 인근해역에서 채집된 쭈굴감펭, Scorpaena miestoma의 생식소 구조, 생식세포의 발달 및 생식주기 등이 광학현미경 조직표본을 기초로 연구되었다. 정소의 내부조직상은 다수의 곡정세관으로 구성된다. 각각의 곡정세관은 여러개의 소낭 구조를 가지는데 각 소낭내의 생식세포들은 같은 단계의 발달상태를 보인다. 난소내부는 난소외막으로 부터 시작된 여러장의 난소박판으로 구성되어 있다. 난원세포는 난소박판의 내부상피에서 유래하며, 난모세포로 성장하면서 난소강쪽으로 돌출되어 난병에 의해 난소박판에 연결된다. 생물학적최소형은 암
