Summary:Sex differentiation and vitellogenin (VTG) and 11-ketotestosterone (11-KT) levels in chub, Leuciscus cephalus L., exposed to 17 beta -estradiol and testosterone during early development, were investigated. Chemical analysis of heterogeneous substances in fish was a reliable method of evaluation of aquatic ecosystem pollution. Steroid hormones were used to simulate the effect of endocrine disruptors on fish under controlled conditions. The exposure of juvenile chub to steroid hormones at the tested concentrations had no measurable effect on levels of 11-KT when compared to the controls. The results showed that that VTG measured in whole body homogenate could be used to determine the effects of exogenous steroids in juvenile chub.
