Abstract

Male fish in several UK estuaries are known to be exposed to oestrogenic contamination, and whilst a limited number of studies have shown that exposure to oestrogens can reduce the reproductive success of fish, the impact of environmentally relevant exposures is less clear. The aim of this study was, therefore, to investigate the effects of exposure to environmentally realistic concentrations of a sewage effluent and the synthetic oestrogen 17a-ethynyl oestradiol (EE2) upon the reproductive success of a marine fish. Sand goby (Pomatoschistus minutus) were exposed for 7 months to EE2 or a sewage effluent containing known xeno-oestrogens (alkylphenol polyethoxylates) and bred using within treatment crosses.
