摘　　要：以卵黄囊期吉富罗非鱼仔鱼为试验对象,对比不同温度诱导对其生长速度、存活率和畸形率的影响。结果表明:经不同温度诱导10 d后,吉富罗非鱼仔鱼的生长率和存活率差异显著,而畸形率差异不明显。其中28℃水温诱导的生长率和存活率最高,生长率显著高于其他各个温度处理组(P<0.05),38℃的生长率和39℃存活率最低,死亡率为100%。上述结果表明,高温诱导显著影响着吉富罗非鱼仔鱼的生长率和存活率,因此在吉富罗非鱼苗种繁育过程中注意合理调节培育温度,提高苗种的质量。In this research,the effects of different temperature inducement on the growth rate,survival rate and aberration rate of the larvae of Genetic Improvement of Farmed Tilapia（GIFT）was studied in the laboratory.The results showed that the growth rate and survival rate of the larvae were significant different after 10 days inducement,but the aberration rate was not obvious.The growth rate and survival rate of the larvae were highest at 28℃,the lowest was at 38℃.The mortality rate at 39℃was 100% after 10 days inducement.Moreover,the growth rate at 28℃ was significant different to the other temperature.Above-mentioned results indicated that high temperature plays very important role in the larvae of the growth rate and survival rate.So we should pay attention to regulate the temperature of the process of the larvae GIFT cultivated,in order to improve the quality of tilapia offspring.
