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

Parentage-based tagging (PBT) and genetic stock identification (GSI) were
used to identify individual coho salmon (Oncorhynchus kisutch) to specific
populations and brood years. 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 1939 coho salmon to the
correct population was 100%, and to correct brood year within population
was also 100%. Inclusion of individuals requiring only a single parental
genotype for identification resulted in assignments of 2101 individuals,
with an accuracy of 99.95% (2000–2001) to population and 100.0% to age.
With 23 regions defined by the coded-wire tag (CWT) program, and
individuals displaying an assignment probability <0.85 excluded
from the analysis, mean 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.
