摘要
秋冬季生殖的真鲷胚胎发育的适宜水温低于２７℃而高于１５℃，最适水温在２４～１８℃范围之内；胚胎发育的生物学零度是１０．６℃，胚胎发育时间与水温呈显著的负相关关系，仔、稚鱼对降温的适应能力与其个体大小，起止温度高低正相关，而与水温的下降速度、下降幅度负相关，水温低于１５℃时容易出现仔、稚鱼大量死亡。
篢he suitable temperature for embryonic development of the Autumn-Winterspowning groups of Red Bream，Pagrus major was below 27℃ and above 15℃，24～18℃was thought to be the optimal temperature.Biological minimium temperature for the eggdevelopment was estimated tp be 10．6℃. The time of the embryonic development wasshorter with higher temperature，and followed the formula：H=338．2259/T-10．6247.The adaptability of the larval and post-larval at lower temperature was related normal-ly to their own body size，the beginning and ending of temperature of the experiments，and related negatively to the speed and range of the changing of water temperature.When the temperature was below 15℃，the mass-mortability could be easily caused.
