Electrophoretic Assessment of the Contribution of Transplanted Scottish Atlantic Salmon ( Salmo salar) to the Esva River (Northern Spain)

The genetic influence of stocking on the Atlantic salmon (Salmo salar) population from the Spanish Esva River was analysed by electrophoresis of protein loci. Genetic variation within parr and mature male parr samples demonstrated that Scottish-origin parr stocked in 1990 survived the first summer....

Description
Summary:The genetic influence of stocking on the Atlantic salmon (Salmo salar) population from the Spanish Esva River was analysed by electrophoresis of protein loci. Genetic variation within parr and mature male parr samples demonstrated that Scottish-origin parr stocked in 1990 survived the first summer. However, samples collected from returning adults in 1990 and 1991 did not indicate any contribution from previous stocking programs. Altered MEP-2* frequencies indicate that the native gene pool may have been disrupted by foreign genomes from precocious males or grilse.
