| 摘 要： | 将源于1、2、3、4尾雌虾的克氏原螯虾仔虾以4种方式混养,每个混养群体共有仔虾24尾,设3个重复。结果表明:亲缘关系对幼年螯虾种内斗争影响显著。随着仔虾来源的增多即亲缘关系复杂性的提高,螯虾的存活率总体呈下降趋势,而残虾率、体长变异系数、体长增长率总体上显著上升。

| Abstract: | The aim of this study was to investigate the importance of relative relationship in growth and survival of juvenile red swamp crayfish,Procambarus clarkii.The juveniles from 1,2,3 or 4 female crayfishes were reared together at a rate of 24 individuals per tank with triplication to determine the growth and survival of the juveniles.Relative relationship was clearly found to affect the growth of the crayfish.On the whole,the crayfish juveniles with more complex relatives had lower survival rate and higher dis... |
