Morphological and genetic comparison between naturally produced smolts of Atlantic salmon, brown trout and their hybrids
Abstract Morphological characters were compared between smolts (standard length 110–220 mm) of Atlantic salmon Salmo salar L., anadromous brown trout Salmo trutta L. and their hybrids captured in River Driva, western Norway. Morphological discrimination between S. salar, S. trutta and their hybrids...
