Abstract

Triploid rainbow trout (Salmo gairdneri) were produced on a large scale practice by the application of moderate heat treatment in 1986. Triploid treatment of the fertilized eggs was carried out with heat shock at $27^{\circ}C$ for 10 to 14 minutes starting 10 minutes after insemination at $10^{\circ}C$. Estimated triploidy ranged from $45\%\;to\;57\%$ ana the incidence of triploidy slightly increased with the treatment time. No significant differences of growth rate were observed between triploidy and diploidy at the early stage of growth. This observation was consistent with results of other fish species and other reports on this species. This heat shock technique, expecting further improvement, should be useful in the mass production of sterile triploid rainbow trout.

1986년초 저자들은 불임 3배체 무지개송어의 대량 생산을 위하여 수정난을 $27^{\circ}C$로 열처리하였다. 그 결과 $50\%$ 전후의 3배체 무지개송어가 유도되었으며 유도된 3배체 송어의 초기 성장률은 여타 보고들과 같이 정상 2배체와 유사하였다. 앞으로 본 방법을 수정개량하여 처리함으로써 산업적으로 중요한 불임 무지개송어의 생산성을 높일 수 있으리라 사료된다.
