摘要/Abstract

摘要： 测定了白洋淀野生日本沼虾不同生长阶段的体长、体重以及肝胰腺和肌肉中RNA/DNA比值,通过回归分析拟合得到体重与体长、RNA/DNA比值与体长关系的数学方程.结果显示,体重与体长的关系可用幂方程(W=0.004 5L3.985 9, R2=0.98,P<0.01)来表示,而肝胰腺和肌肉中RNA/DNA比值与体长的关系则为指数式方程(RL=-0.225 3e0.74L, R2=0.968, P<0.01; RM=0.051 2e1.195 1L, R2=0.974,P<0.01),与体重关系为RL=1.592 4e0.821 5w(R2=0.969 9, P<0.01)和RM=1.198 9e1.330 5w(R2=0.981 3,P<0.01).RNA/DNA比值能较好指示日本沼虾的生长状况,为日本沼虾的生物学研究提供了重要的参考指标.
