Concentrations of DDT in muscle tissue of channel catfish, Ictalurus punctatus, from the Des Moines River, Iowa, were compared in relation to length, age, sex, and fat content. Residue concentrations were not correlated with sex. Although residue concentrations were significantly correlated with size-related factors and fat content, they varied widely. Therefore, predictions of DDT concentrations in individual catfish on the basis of length, age, or muscle fat content may be grossly inaccurate.
对来自爱荷华州得梅因河的斑点叉尾鮰（Ictalurus punctatus）肌肉组织中的滴滴涕（DDT）浓度，就鱼的长度、年龄、性别和脂肪含量进行了比较。残留浓度与性别无关。尽管残留浓度与大小相关因素和脂肪含量显著相关，但它们的差异很大。因此，根据长度、年龄或肌肉脂肪含量来预测个体鲶鱼体内的滴滴涕浓度可能会非常不准确。
