Abstract
For the mass production of all-female triploid rainbow trout during fall season, treatment of short-term daylength from 30th of August, 1994 and chromosome manipulation by heat shock were performed with 3-year-old fish. After treatment of short-term daylength to fish, we successfully obtained the fertilized eggs from all treated fishes. However, hatching rate were significantly lower than that of natural spawning season (P<0.05). Hormonal treatment using 3mg of
무지개송어 전 암컷 3배체 조기난 생산을 위해 1994년 9월 30일부터 3년생 암컷 친어에 대하여 광주기를 단일 처리하여 조기 산란 및 성전환 유도와 고온 처리에 의한 염색체 조작을 실시하였다. 광주기 조절이 시작된지 1개월째 170마리의 암컷으로부터 340,000개의 난을 얻었다. 그러나, 부화율에 있어서는 자연 상태의 산란기때 부화율에 미치지 못하는
