Regional differentiation of North American Atlantic salmon at allozyme loci
Allozyme variation was characterised by starch gel electrophoresis at 23 enzyme coding loci and one regulatory locus in Atlantic salmon from 53 rivers in Eastern Canada, encompassing the majority of the species' North American range. Variation among rivers was highly heterogeneous and eight of...

Allozyme variation was characterised by starch gel electrophoresis at 23 enzyme coding loci and one regulatory locus in Atlantic salmon from 53 rivers in Eastern Canada, encompassing the majority of the species' North American range. Variation among rivers was highly heterogeneous and eight of the 15 polymorphisms showed regionally restricted distributions. Nearest neighbour joining (NJ) analysis and multi-dimensional scaling suggest six distinct regional groups; Labrador/Ungava, Gulf of Saint Lawrence, Newfoundland (excluding Gulf rivers), the Atlantic shore/Southern Uplands of Nova Scotia, the inner Bay of Fundy, and the outer Bay of Fundy. Approximately 25% of observed genetic variation was distributed among these regions with a weak though significant overall correlation of genetic and geographic distance (Mantel Test, r = 0·255, P = 0·005).
