【摘要】 运用统计分析方法研究了丁鱼岁、川鲶个体的含肉率和可量性状之间的相关性。结果显示:1)丁鱼岁的含肉率为64.04%,体长/体高的比值与丁鱼岁的含肉率呈显著负相关性(Pearson系数分别为-0.783*,P<0.05);体高/头长的比值分别与丁鱼岁的含肉率显著正相关(Pearson系数分别为0.782*,P<0.05)。2)川鲶的含肉率为68.47%,体重与川鲶的含肉率呈较高的负相关性(Pearson系数为-0.735,),其它指标相关性较低。结果表明,利用可量性状预测丁鱼岁、川鲶的含肉率是可行的。更多还原

【Abstract】 The correlation between body measurements and fillet yield in Tinea tinea and Silurus meriaionalis Chen×Silurus spp was studied by statistics analysis.1 ).The average fillet yield in Tinea tinea was 64.04%and the fillet yield showed a significant negative correlation to length / body depth (Pearson coefficient was -0.783*,P<0.05);the fillet yield showed a significant correlation to body depth/ head length(Pearson coefficient was 0.782*,P<0.05).2) The average fillet yield in Silurus meriaionalis Chen×Silurus spp was 68.47%and the fillet yield showed a stronger negative correlation to body weight(Pearson coefficient was -0.735).It was concluded that it is possible to predicting fillet yield based on body measurements in Tinea tinea and Silurus meriaionalis Chen×Silurus spp.更多还原
