Electrophoretic examination of 56 wild Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) from the Stewiacke River, Nova Scotia, revealed one individual believed to be a hybrid between these two species. The possibility of loss of the genetic integrity of each species is considered. A long history of sympatry between Atlantic salmon and brown trout in Europe may have prevented the formation of hybrid swarms as occurred in western North America following introduction of nonindigenous Salmo.Key words: electrophoresis, introgression, enzymes, genetic interaction
