We investigated the viability and seawater tolerance of all possible combinations of triploid and diploid hybrids between chinook (Oncorhynchus tshawytscha), chum (O. keta), and pink salmon (O. gorbuscha) in two brood years. Triploidy (induced by heat shock shortly after fertilization) was determine...
