Abstract
Embryos at four stages of development and the newly hatched larvae of zebrafish (Brachydanio rerio) were exposed to selenium concentrations between 0.5 and 10 μg/ml to establish the toxic levels at the different stages. Embryo mortality was negligible at all selenium concentrations. Following hatching, mortality among the larvae sharply increased at concentrations of 3 μg/ml or greater irrespective of the embryonic stage when exposed. For most treatments, over 90% of the larvae died within 10 days of hatching. The mortality rate for larvae exposed to selenium after hatching was slightly less.Keywords
