dc.description.abstract在水温(27±2)℃、盐度29±2、pH 7.8~8.5、光强1 000 lx的条件下,对来自中国台湾省的体质量为35~45 g的凡纳滨对虾(Litopenaeus vannameiBoone 1931)亲虾的性腺成熟节律和交配进行了为期73 d的繁育实验,样品为1 300对,3个批次。结果表明,雌虾术后卵巢成熟率分4期:Ⅰ期(1~9 d)入池适应术后效应期;Ⅱ期(10~16 d)低成熟率期,Ⅲ期(17~51 d)成熟率渐上升期,Ⅳ(52~73 d)平稳期;雄虾精荚形成率分3期:Ⅰ期(1~12 d)入池适应与术后效应期;Ⅱ期(13~51 d)平缓上升期,Ⅲ期(52~73 d)平稳期。在95%的概率保证程度下,雌亲虾卵巢成熟率为9.73%,波动区间9.14%~11.53%;雄虾精荚形成率6.63%,波动区间5.87%~7.38%;平均交配率为61.43%,波动区间58.85%~64.00%。在繁殖过程中,雌虾卵巢再成熟时间间隔9.68 d,可多次成熟的次数19.49次,雄虾精荚再形成时间15.10 d,可多次形成的次数为12.50次。此外还就影响雌虾卵巢成熟和雄虾精荚形成的因素以及如何提高交配率进行了详细的讨论... 【英文摘要】 Beginning in 1988,Litopenaeus vannamei was introduced into China,and 1998 on a commercial scale.China now has a large and flourishing industry for Litopenaeus vannamei,with Mainland China producing more than 270?000 metric tonnes in 2002,300?000 metric tonnes(71 percent of the country's total shrimp production) in 2003,and 367?500 metric tonnes(78.5 percent of the country's total shrimp production) in 2004,which is higher than the current production of the whole of the Americas.The intensive culture of Lito...zh_CN
