摘要:
Abstract.The pre‐acidification level of Atlantic salmon,Salmo salarL., production in Norway was estimated from accessible rearing habitat, potential smolt production, smolt to adult survival, and mean adult weight. Atlantic salmon have been virtually lost in 25 rivers due to acidification. In total, 340.6km of river is affected, and this corresponds to a rearing area of 2044.8 ha. The total annual number of adult salmon lost was estimated to be between 92016 and 306720 individuals, weighing some 345‐1150 ton
