摘要
1987年11月至1988年6月在福建佛昙湾两口换水条件好、砂泥底质的深水养虾池进行长毛对虾室外越冬和性腺促熟试验,结果表明:这两口池长毛对虾越冬成活率分别为75%和84%,性腺促熟率分别达到82%和61.3%,每尾亲虾的育苗量分别为3.5万尾和2.5万尾,切除眼柄促熟率的亲虾每尾育苗量也分别达到3.8万尾和2.5万尾,达到了生产的要求。文中还分析了这两口池促熟率差异的原因。
The outdoor prawn culture ponds in the Futang Bay has an average bottom temperature of 15℃ in winter. The average water depth was 1.8m with a maximum depth of 2～3m. Water exchanged smoothly in either spring or ebb tide. The bottom consisted of sandy mud. Experiments were carried out, in the period from November to May or June of the next year, on outdoor wintering and gonad ripening promotion of prawns Penaeus penicillatus. The results indicate that the penaeus prawn wintered and sexual gonad facilitaded simultanously in the pond had the wintered survial rate of 75% and 84%, the gonad ripening promotion rate of 82% and 61.3%, and the breeding rate of each parent 35 thousand and 29 thousand larva. The breeding rate of each eyestalk-removed parent produced 38 thousand and 25 thousand larva, meeting the requirement of commercial production. This paper has also analyzed the resons for different gonad ripening promotion rate between the two ponds.
