Range-wide regional assignment of Atlantic salmon (Salmo salar) using genome wide single-nucleotide polymorphisms

摘要: Abstract The estimation of stock specific exploitation is imperative to fisheries management and the conservation biodiversity, particularly in instances where simultaneously exploit mixtures stocks. Mixed harvests are common species that have extensive marine migrations, such as Atlantic Pacific salmon. Here we develop a range-wide genetic baseline for salmon (Salmo salar) from North American European rivers allow regional assignment individuals targeted international mixed fisheries. A combination published data additional genotyping was used assemble dataset 96 SNPs 285 populations assignment. Clustering samples identified 20 eight reporting groups with mean individual accuracy 90% (range 70–100%). This applied disentangle composition subset West Greenland fishery. Genetic mixture analysis revealed both originated multiple regions, 92% originating United Kingdom Ireland, three regions; Gulf St. Lawrence (28%), Gaspe Peninsula (23%), coastal Labrador (21%). represents significant resource quantification migration patterns at sea.
