摘 要:以状黄姑鱼为母本、大黄鱼为父本的人工杂交试验表明 :在温度 17~ 2 0℃、盐度 2 9.9~ 30 .8的条件下 ,杂交卵经 39.9h孵出 ,受精率为 5 8.9% ,孵化率为 1.4% ,仔鱼存活 18d .对照组状黄姑鱼受精率 95 % ,受精卵孵化率 5 6 % .杂交组受精卵的胚胎发育与母本状黄姑鱼的胚胎发育主要差别为 :杂交卵在进入原肠期时 ,多数胚胎发育速度明显变慢 ,囊胚不能正常下包 ,胚胎畸形率较高 .The embryonic development of hybrid combination between Nibea miichthioides ♀ and Pseudosciaena crocea ♂ was studied.The results showed that the oosperm were hatched out in 39.92 h in the state of 17~20 ℃ and 29.9~30.8 of salinity, with the fecundation rate, 59.9% and the hatching rate, 1.4%. The cultivated larvae had been alive for 18 days. As a control group, the fertilization rate of N. miichthioides was 95%, and the hatching rate, 56%. The main difference between the embryonic developments of the crossbreeding and the oosperm of the female parent was likly that the developing speed of the crossbreed was much slower than that of the female parent when they grew to the gastrula, and the blastoderm couldn't develop downward normally, which led to a high proportion of malformations among larvae. The comparison with the male parent and some key factors that affected the intercrossing were also discussed.
