摘要
对吉富品系尼罗罗非鱼（简称吉富鱼）从淡水移入不同盐度咸水的平均死亡时间（MST）和半数死亡时间（ST50）的研究结果表明，MST和ST50值随移入盐度（S）增高而减少，相关性非常显著，其关系式为：MST＝494.5／（S－17.0）（P＜0．01），ST50=495．1／（S-17.1）（P＜0.01）。96h半致死盐度（MLS－96）随吉富鱼体重增加而增大，相关性也非常显著，其关系式为：MLS－96=15.6W0.045（P＜0.01）。吉富鱼适宜在0－12的盐度不养殖，在24‰以上的盐度下不宜养。
GIFT strain of Nile tilapia was directly transferred from freshwater to brackishwaters with differentsalinity. Mean survival time(MST) and 50% survival time(ST,) was observed. MST and ST50 increased assalinity(S) decreased, highly significantly(P <0. 01 ). The relation forms are: MST = 494. 5 / (S - 17.0),ST50= 495. 1 / (S - 17. 1 ). Median lethal salinity - 96 hours(Mis - 96) of GIFT tilapia increased as itsweight(W) increased, highly significantly (P <0. 01 ) . Their relation form is: Mis - 96 = 15. 6W0. 045 (P<0. 01 ). GIFT tilapia could be cultured at 0 ~ 12 salinity, but couldn' t be suitably cultured above 24salinity.
