Abstract
Nine males within a group of approximately 200 pink salmon (O. gorbuscha) reared in heated sea water became sexually mature in Oct. of the year of hatching. These mature males (average wt = 119.44 g; average length = 19.8 cm) were larger than the immature males (average wt = 92.22 g; average length = 18.9 cm) but not significantly so. This is the 1st record of precocious development in pink salmon other than as a result of the use of exogenous gonadotropin.This publication has 1 reference indexed in Scilit:
