摘　　要：以橙色莫桑比克罗非鱼与荷那龙罗非鱼的杂交子代莫荷罗非鱼（Oreochromis mossambicus♀×O.hornurum♂）为实验材料,通过急性耐盐实验和慢性耐盐驯化实验,对其幼鱼耐盐性进行了初步研究。结果表明：莫荷罗非鱼的96 h半致死盐度为（33.74±0.94）‰;在每天将盐度提高8‰的情况下,其半致死盐度为（112.93±4.87）‰,驯化致死盐度为128‰-136‰。实验表明,莫荷罗非鱼经过驯化可以耐受更高盐度的水环境,具有在海水中养殖的潜力。Salt -tolerance of the hybrid tilapia （Oreochromis mossambicus♀×O.hornurum ♂） was studied by acute salt test and chronic salt test.The results showed that median lethal salinity -96 h of the hybrid was （33.74 ±0.94）‰, medi-an lethal salinity of daily increase in salinity of 8‰ was （112.93 ±4.87 ）‰, and the domestication fatal salinity was 128‰ -136‰.The results suggested that the hybrid could tolerate higher salinity of aquatic environment after domestica -tion and had the potential to be cultured in seawater .
