Environmentally Induced Precocious Sexual Development in the Male Pink Salmon ( Oncorhynchus gorbuscha )

Nine males within a group of approximately 200 pink salmon (Oncorhynchus gorbuscha) reared in heated sea water became sexually mature in October of the year of hatching. These mature males (average weight = 119.44 g; average length = 19.8 cm) were larger than the immature males (average weight = 92....
