摘要
试验在塑料大棚简易水泥池温室内,对40组亲鱼孵化的26.19万尾乌鳢幼体经过25d 培育后(温室内培育10d,室外网箱内培育15d),获得规格为2～3cm 夏花18.00万尾,这阶段成活率达到68.7%,然后放入室外土池中培育50d,获得规格为10～15cm 鱼种10.30万尾,这阶段成活率达到57.3%,总的成活率为39.4%。
The experiment were conducted to culture 261900 parrs which were hatched by 40 pairs Ophiocephalus argus Cantor about 25 days （10 days in greenhouse, 15 days in net-box out of the door）in the simple plastic greenhouse with concrete pool,acquiring 180000 fish as 2-3 cm.The survive ratio was 68.7% in this phage.Then cultured them in the pool which was made of solid about 50 days,acquiring 103000 fish as 10-15cm.The survive ratio was 57.3% in this phage.The total survive ratio was 39 4%
