摘要:
1995-1997年,以暗纹东方鲀进行人工繁殖,经LHRH-A2催熟处理,雌鱼的性腺可以发育到Ⅳ期末,性腺发育达到Ⅳ期中以后的雌鱼注射激素能引起正常的排卵反应.试验用的催产药物为 LHRH-A2、HCG和PG.在水温 16-21℃的条件下,效应时间为6-86 h,平均催产率为87.5%,平均受精率为 61.8%,平均孵化率为 51.7%.在水温20℃时,胚胎发育历时154 h孵出.

Abstract:
Parents fish of Taking fugu obscurus were collected for artificial reproduction in the lower reaches of the Yangtze River from 1995 to 1997. The sexual gland of female puffer can develop to the end of IV period through treating with LHRH-A. The female puffers which the sexual glands have developed to the middle of W period could be induced spawning through in jecting hormone. The hormone for inducing spawn of the experiments is LRH-A、HCG and PG. At the temperature of 16-21 ,the time of effect is 6-86 hours, the average rate of spawning is 84.0%, the aver-age rate of fertilizing is 61. 8%, the average rate of hatching is 51.7%.At the water temperature of 20C°, the time of embryonic development is 154 hours.
Key words:  Taking fugu obscurus  reproduction  induce spawn  hatch  embryonic development
