1. 1. A broad range of tetrazolium oxidase mobility was found among rainbow trout ( Salmo gairdneri) and Pacific salmon ( Oncorhynchus) native to North America. 2. 2. Three forms of polymorphisms in rainbow trout and chinook salmon ( O. tshawytscha) were interpreted as reflecting allelic relationships. Three-banded heterozygous phenotypes suggested that the active enzyme is a dimer. 3. 3. Similar gene frequencies were observed for rainbow trout sampled over a broad geographic range; a significant difference in gene frequencies was found between chinook salmon taken from high seas areas of the North Pacific Ocean and those from Seattle, Washington.
