title: Effect of acute exposure to crude petroleum on some reproductive hormones in salmon and flounder.
abstract: 1. The concentration of total (free + conjugated) androgens in plasma of sexually mature male salmon and flounder was generally lower in oil-exposed fish. 2. Exposure to crude oil inhibited some testicular development of salmon during the final stages of maturation. 3. Oil exposure had no effect on levels of total plasmatic androgens or estradiol in male and female flounder during gonadal recrudescence. 4. Aryl hydrocarbon hydroxylase activity increased in liver and kidney of both species. 5. Sperm, collected from salmon exposed to oil, fertilized eggs from non-exposed females to produce normal alevins.
