Discordant phenotypic variation in sympatric resident and anadromous Atlantic salmon ( Salmo salar ) populations
Sympatric but electrophoretically distinguishable resident and anadromous Atlantic salmon (Salmo salar) populations from Little Gull Lake, Newfoundland, were compared for meristic and morphometric variation. No morphometric differentiation was detected. As the two populations have similar juvenile r...
