Abstract
The reproductive success of 30 female Lake Michigan chinook salmon (Oncorhynchus tschawytscha) was evaluated and compared to the status of two hepatic enzyme systems proposed as sensitive biochemical indicators of exposure to planar polychlorinated aromatic hydrocarbons, including certain polychlorinated biphenyls, polychlorinated dibenzofurans and polychlorinated dibenzodioxins. Fertilizability, hatchability and egg and fry mortality varied significantly among the fish. Hepatic monooxygenase and glutathione S-transferase activities and cytochrome P-450E concentration also varied markedly among the fish. There was, however, little correlation between reproductive success and the three biochemical indicators of contaminant exposure.
