Abstract
Gonad and blood samples were taken from cultured greenling (Hexagrammos otakii), and changes of steroid hormone levels in serum were examined in relation to the gonadosomatic index (GSI). GSI of female and male were not changed significantly between March and August and then began to increase from September showing the highest value in January. Hepatosomatic index (HSI) of female was the highest in December,'then decreased gradually until May.
양식 잠재력이 높은 어종인 쥐노래미 (Hexagrammos otakii)의 번식생리에 관한 기초 자료를 얻고자 쥐노래미의 생식주기와 함께 혈청의 성 스테로이드호르몬의 변화에 관하여 연구하였다. GSI는 암컷과 수컷에서 3월부터 8월까지 유의한 변화를 보이지 않다가 9월부터 상승하기 시작하여 1월에 최고값을 보였다. 암컷의 혈중
