Electrophoretic Variants of L-Alpha-Glycerophosphate Dehydrogenase in Pacific Ocean Perch (Sebastodes alutus)

Abstract

Three phenotypes of L-alpha-glycerophosphate dehydrogenase (α-GPDH) were found in muscle extracts of Pacific ocean perch by starch-gel electrophoresis. No association was obvious between alpha-glycerophosphate phenotype and sex or stage of maturity. The observed phenotypes were presumed to be under the control of two allelic genes, F and S. This assumption was supported by the distribution of phenotypes of fish collected off the coasts of Washington and Oregon. This report is the first on genetic variants of an enzyme in Pacific ocean perch and suggests that isozymes of α-GPDH may be useful in population studies of this species.
