研究不同温度对斑鳜（ Siniperca scherzeri）胚胎发育的影响。结果表明：在18～28℃温度范围内，斑鳜胚胎均能孵化出膜；随温度升高，胚胎发育达囊胚期、原肠期和出膜期的时间均相对缩短，温度对囊胚期前的发育进程影响较小，胚胎发育至囊胚期后，温度升高胚胎发育进程明显加快；孵化时间随温度的升高而缩短，孵化时间T与温度x呈极显著的负相关关系， T＝306738 x－2.463， R2＝0.9966（ P＜0.01）；在18～26℃温度范围内，胚胎发育到原肠中期的死亡率较低，孵化率较高，且组间差异不显著（ P＜0.05），温度达28℃时，胚胎发育到原肠中期的死亡率极显著上升，孵化率下降极显著（P＜0.01），孵化率y与温度x之间存在极显著的二次曲线相关关系，y＝－1.0321 x2＋44.107 x－379.99，R2＝0.9174（ P＜0.01）。斑鳜受精卵孵化的最适温度范围为20～26℃。

The effects of temperature on the embryonic development of Siniperca scherzeri were investigated in this study . The results showed that the embryo could be hatched at the range of 18~28℃, and with the increase of temperature , the periods of embryonic development reaching blastula , gastrula and hatching stage were relatively shorter .Temperature had little effects on the development before blastocyst stage .After embryos developped into blastocyst stage , elevated tempera-ture significantly speed up the process .Incubation time shortened with the increase of temperature .There was a very sig-nificant negative correlation between incubation time ( T) and temperature ( x) , and the equation was T=306738 x-2.463 , R2 =0.9966 ( P<0.01 ) .The mortality rates were lower and the hatching rates were higher when embryonic developped in -to the mid gastrula stage at the range of 18~26 ℃, and the difference between groups was not significant ( P<0.05 ) . When the temperature reached 28 ℃, the mortality rate of the mid gastrula stage increased very significantly , and the hatching rate decreased significantly ( P<0.01 ) .There was a significant square curve correlation between hatching rate (y) and temperature(x), and the equation was y=-1.0321x2 +44.107x-379.99, R2 =0.9174(P<0.01).The op-timal temperature range for the hatching of fertilized eggs was 20~26 ℃.
