Assessment of fish health in Areas of Concern on the Canadian side ofthe Great Lakes: exposure to environmental estrogens

As part of a broad assessment of wildlife health in Areas of Concern  (AOCs) on the Canadian side of the Great Lakes we are examining wild  fish and caged rainbow trout (Oncorhynchus mykiss) for evidence of  exposure to estrogenic substances. We divide each AOC into impact,  downstream, and an upstream reference site. At each site we seek to  capture 2  adult male and female specimens of a water column and a  bottom dwelling species.  We also cage rainbow trout at sites in the 3  treatment zones. The presence of vitellogenin (Vtg) in the plasma of  male fish is indicative of exposure to environmental estrogens. A  decrease in the concentration of plasma Vtg in female fish from the  impact zones compared with females from the downstream or reference  location would be indicative of possible exposure to anti-estrogens.
