摘要
采用自然苗培育成的1龄(鱼免)鱼,通过'春肥、夏育、秋繁、冬保'8字方针培育成亲鱼,性成熟率达到95%.经LHRH-A3 0.8～1.8 μg /kg催产并放人产卵池自行产卵,获产率达到96.83%.获受精卵650万余粒,受精率达到52%.受精后21.8 h孵化出鱼苗,孵化率达到70%.
One year old brood - stock of Chinese drum Miichthys miiuy （Basilewsky）collected in wild was cultured in spring and summer, induced to spawn by injection of LHRH- A3（0.8～ 1.8μg/kg）in autumn and wintered in winter. The maturity rate was 96.83 %. The amount of fertilized eggs was about 6.5 million . with fertilization rate of 52%. The embryo hatched 21 hours and 48 minutes after fertilization with incubation rate of 70%.
