Data from: Population and individual identification of Coho Salmon in British Columbia through parentage-based tagging and genetic stock identification: an alternative to coded-wire tags|鱼类种群鉴定数据集|遗传分析数据集

Parentage-based tagging (PBT) and genetic stock identification (GSI) were used to identify individual Coho Salmon (Oncorhynchus kisutch) to specific populations and broodyears. In total, 20,242 individuals from 117 populations were genotyped at 304 single nucleotide polymorphisms (SNPs) via direct sequencing of amplicons. Coho Salmon from 15 populations were assigned via parentage analysis that required the genotypes of both parents. The overall accuracy of assignment for 1,939 Coho Salmon to the correct population was 100%, and to correct broodyear within population was also 100%. Inclusion of individuals requiring only a single parental genotype for identification resulted in assignments of 2,101 individuals, with an accuracy of 99.95% (2,000/2,001) to population and 100.0% to age. With 23 regions defined by the CWT program, and individuals displaying an assignment probability < 0.85 excluded from the analysis, average regional assignment accuracy of individuals via GSI was 98.4% over all 23 regions. A PBT/GSI or PBT system of identification will provide an alternate method of identification in the assessment and management of Canadian-origin Coho Salmon relative to the existing CWT program.
