Genetic determination of the contribution of stocked and wild Atlantic salmon, Salmo salar L., to the angling fisheries in two Spanish rivers
From 1983 to 1986 the Rivers Ason and Nansa (northern Spain) were stocked with over 100 000 eyed ova year −1 from a Scottish hatchery in an effort to increase angling catches of Atlantic salmon. An inherent genetic marker was used to estimate the contributions of stocked and wild fish from these yea...
