Abstract
Electrophoretic variation of Atlantic salmon NADP‐isocitrate dehydrogenase in liver extracts of material from Ireland is interpreted in terms of two loci, IDH‐A and IDH‐B, coding for cytoplasmically‐located isozymes. The IDH‐A locus is polymorphic with qIDH‐A1=0.18 and qIDH‐A2=0.82. This polymorphism is of potential value for investigating the population genetics of the two races of Atlantic salmon in Ireland. An additional, monomorphic band which appears in heart extracts may be a mitochondrial enzyme coded by a third locus.Keywords
