Inter‐ and intra‐population morphological differences between wild and farmed Atlantic salmon juveniles
Whether population‐specific morphological differences were detectable in small (26–52 mm) Atlantic salmon Salmo salar parr reared under similar conditions was tested. Discrimination based on morphological characters was total (100%) between the fish of farmed origin (from AquaGen) and four wild fish...
