摘要:
为研究红螯螯虾(Cherax quadricarinatus von Martens)不同生长时期的表型特征,统计了3月龄、4.5月龄和6月龄3个生长时期红螯螯虾的体重Y1、肝胰腺质量Y2、全长X1、头胸甲长X2、头胸甲宽X3、腹节总长X4、第一腹节长X5、第一腹节宽X6和掌节长X7共9个性状,对比3个生长时期各表型性状间的差异和相关性,分析不同生长时期各表型性状在雌性与雄性群体间的差异,采用多元回归分析分别研究了不同生长时期表型性状与体重的关系,并构建回归方程。结果显示,头胸甲和腹节的长度比例在幼虾和成虾中保持一致,而宽度指标(头胸甲宽、第一腹节宽)在6月龄阶段显著(P<0.05)增长。随着红螯螯虾的生长,大部分性状间的相关性降低,雌雄群体间表型性状的差异逐渐增加。3月龄阶段的回归方程为Y1=-31.33+0.73X2+0.91X3;4.5月龄阶段的回归方程分别为Y1=-65.25+1.29X3+0.89X4+1.46X6(雌性)、Y1=-69.67+1.17X3+0.40X7+1.77X6+0.59X4(雄性);6月龄阶段的回归方程分别为Y1=-79.77+1.01X1-1.89X6+1.15X7(雌性)、Y1=-98.02+0.72X1+1.22X7(雄性)。从3个生长时期的回归方程可以看出,各表型性状在不同时期与体重的相关性差异较大。研究结果可为红螯螯虾的选育工作提供理论依据。
