Direct DNA sequencing is powering a revolution in the application of genetics to resource management, with parentage-based tagging (PBT) increasingly applied to salmon fisheries and hatchery brood stock management and assessment. Genetic stock identification (GSI) and PBT were applied to assessment of 2018 coho salmon (Oncorhynchus kisutch) ocean fisheries and hatchery brood stocks in British Columbia (BC), Canada, with 6391 individuals successfully genotyped in fishery samples and 7805 individuals genotyped in 40 hatchery brood stocks. Population-specific contributions to mixed-stock fisheries and exploitation rates were estimated with coded-wire tags (CWTs) and GSI–PBT technologies for six populations. PBT assignments, verified by CWTs, were 100% accurate for 308 individuals with respect to population of origin and age. There was generally reasonably close agreement of estimated population-specific exploitation rates between CWT and genetic methods. We conclude that a genetic approach can improve upon the results available from the current CWT program for assessment and management of coho salmon fisheries and hatchery brood stocks in BC and provide information critical to aid in implementation of Canada’s Policy for Conservation of Wild Pacific Salmon.

Tagging Methods

<em>Abstract</em>.—The emerging use of genetic markers for stock identification is advantageous as this technique utilizes an inherent permanent mark, it eliminates stress associated with conventional tagging methods, and mark recovery is nonlethal. In controlled experiments, increased accuracy and reliability have been demonstrated with genetic tags, as compared to other commonly used markers. While a variety of genetic markers exist for fish identification, microsatellites are preferred because of their polymorphic nature and versatile use, including identification of population structure, measures of genetic diversity, and parentage analysis. Microsatellites provide a cost-effective tool for a variety of applications, including their use in complex experimental designs, as well as responsible genetic population management. We provide examples of the use of microsatellites as genetic tags in South Carolina striped bass <em>Morone saxatilis</em>, describing an experimental restoration effort in the Ashley River and a large-scale stock enhancement effort for the Santee-Cooper reservoirs.
