摘要
利用HCG +鲤鱼PG以及LRH -A +DOM对斑驳尖塘鳢进行人工催产苗种培育的研究。结果表明 ,LRH -A +DOM组的催产效果 (75 % )要好于HCG +鲤鱼PG组 (5 0 % ) ;效应时间为 2 2～ 36h ,在水温 2 7～ 2 9℃时 ,受精卵孵化时间为 5 6～ 98h ;共获苗 34.8万尾 ,平均孵化率为 89%。
HCG, CARP PG AND LRH-A, DOM WERE USED INDIVIDUALLY TO OBSERVE THE EFFECTS OF ARTIFICIAL SPAWNING ON THE MARBLE GOBY TO BREED HATCHLINGS. THE RESULTS SHOWED THAT THE EFFECT OF ARTIFICIAL SPAWNING WITH LRH-A AND DOM (75%)WAS BETTER THAN THAT WITH HCG AND CARP PG (50%). RESPONSE TIME WAS BETWEEN 22～26 HOURS. HATCHING TIME WAS BETWEEN 56～98 HOURS AT THE WATER TEMPERATURE OF 27～29 ℃. 348,000 HATCHINGS WERE OBTAINED AND AVERAGE HATCHING RATE WAS 89%.
