| 摘 要： | 2010年12月—2011年3月对南京地区杂交青虾(Macrobrachium nipponensis)"太湖1号"越冬的成活率及生长情况进行了研究。结果显示,越冬后,"太湖1号"青虾的产量与规格均比放养时明显提升(P<0.05),平均成活率为(84±9.17)%,成活率较高。各次采样的体长(x,cm)体重(y,g)方程分别为:y=0.024x2.808,R2=0.958;y=0.039x2.519,R2=0.857;y=0.016x3.085,R2=0.956;y=0.021x2.917,R2=0.923;y=0.015x3.120,R2=0.882。越冬前期为负异速增长(b<3),越冬中期为等速增长(b≈3),越冬结束后为正异速增长(b>3)。

| Abstract: | From December,2010 to March 2011,survival rate and growth of over-wintering oriental river prawn hybrid "Taihu 1#" were studied in Nanjing.The results showed that the yield and specification of Taihu 1# increased significantly and had a higher survival rate of(84±9.17)% after over-wintering.The length-weight relationships of different period were y=0.024x2.808,R2=0.958;y=0.039x2.519,R2=0.857;y=0.016x3.085,R2=0.956;y=0.021x2.917,R2=0.923;y=0.015x3.120,R2=0.882,respectively.The prawns exhibited negative allometric growth in prophase of over-wintering(b<3),isometric growth in metaphase of over-wintering(b≈3)and positive allometric growth after winter(b>3). |
