Toxicity of 3,4-dichloroaniline to perch (Perca fluviatilis) in acute and early life stage exposures

subject

description

Abstract The toxitity of 3,4-dichloroaniline to perch was investigated in order to compare the sensitivity of crucial life stages with common test fish like zebrafish. Although in the acute toxicity test perch were more sensitive by a factor of five, larval sensitivity was in the same range in both species as well as in other egg-laying species. In spite of different water temperature and size, the zebrafish is a good model to predict early life stage toxicity of 3,4-DCA to the compared European freshwater species. Perch larvae are not suited for early life stage tests, as they are sensible towards experimental conditions and perform early cannibalism.
