Discrimination between Atlantic salmon (Salmo salar L.) of North American and European origin
In this paper, scale characters were used to develop and test a statistical model to classify Atlantic salmon( Salmo salar L.) caught at West Greenland as either North American or European in origin. In particular, scale samples collected in 1980 from salmon caught in Europe and North America were u...
