THE PERFORMANCE OF ALL-FEMALE DIPLOID AND TRIPLOID ATLANTIC SALMON SMOLTS ON TRANSFER TOGETHER TO SEA-WATER

On transfer to sea water for 45 days, the return of appetite was later and growth rates tended to be lower for triploid Atlantic salmon, Sal mo salar, reared together with diploid Atlantic salmon. All mortalitie s comprised of triploid salmon (29%) and were attributable to failed s melt syndrome. No correlation was found between the growth of diploid or triploid fish in fresh water and their subsequent growth on transfe r to sea water. (C) 1996 The Fisheries Society of the British Isles
