摘要 为寻找合理的方法评估比较克氏原螯虾和红螯鳌虾出肉率的高低,从而为其选育工作提供科学依据,运用统计分析方法研究了2种虾的出肉率和可量性状之间的相关性。结果表明:红螯螯虾出肉率高于克氏原螯虾出肉率,第1腹节宽为影响克氏原螯虾出肉率的重点性状;体长和头胸甲长为影响红螯螯虾出肉率的重点性状,全长次之。得出结论:(1)可量性状与出肉率的相关性相较于可量性状与肉质量的相关性更能突出重点性状;(2)通过测量可量性状或通过性状比值进行克氏原螯虾和红螯螯虾出肉率方面的选育都是可行的。 This paper provided a measure to estimate the meat yield and to selective breed of Procambarus clarkii and Cherax quadricarinatus.The correlation between meat yield and body measurements in these two kinds of crayfish were studied by statistics analysis.The results showed that,the meat yield value of Cherax quadricarinatus was higher than that of Procambarus clarkii.First abdominal segment width was the main variable to Procambarus clarkii.Body length and carapace length were the main variables to Cherax quadricarinatus,followed by total length.It was concluded that:(1) the correlation to meat yield was more significant than that to body weight;(2) it was possible to predicting meat yield based on ratio of two body measurements or the individual variable in Procambarus clarkii and Cherax quadricarinatus.
