The effects of temperature on the embryonic and larvae development were investigated in this study. The results showed that the embryo could be hatched out at the range of 21～29℃. There was significant negative correlation between embryonic development time (y) and temperature (x) : y =993017x~(3.0318), R~2 =0.9614(P<0. 01) , and between accumulative temperature (y) and temperature (x): y =993017x~(2.0318), R~2 =0.9179(P <0.05). The suitable temperature range for fertilized eggs hatching was 21～29℃, and the optimal range was 23～27 ℃. The development and growth of larvae were faster along with rising of temperature, and the suitable temperature range for development and growth of larvae was 23～31℃, and the optimal range was 25 ～31℃. The results showed that the embryo and larvae development could be accelerated along with suitable increasing temperature in the suitable temperature range.%研究了温度对中华倒刺鲃(Spinibarbus sinensis)胚胎与仔鱼发育的影响.结果显示:在21～29 ℃温度范围内,胚胎均能孵化出膜,孵化时间y与温度x成极显著的负相关关系,y＝993017x~(-3.0318),R~2＝0.9614(P<0.01);孵化积温y与温度x的关系式为y＝993017x~(-2.0318),R~2＝0.9179(P<0.05).胚胎发育的适宜温度范围为21～29 ℃,最适温度范围为23～27 ℃.仔鱼生长发育随温度的升高而加快,仔鱼生长发育的适宜温度范围为23～31 ℃,最适温度范围为25～31 ℃.结果表明,在适宜温度范围内,适当升温可以加快中华倒刺鲃胚胎与仔鱼发育的进程.
