Low genetic diversity, local-scale structure, and distinct genetic integrity of Korean chum salmon () at the species range margin suggest a priority for conservation efforts.

Chum salmon () is an ecologically and economically important species widely distributed across the North Pacific Ocean. However, the population size of this fishery resource has declined globally. Identifying genetic integrity, diversity and structure, and phylogenetic relationships of wild populations of over an entire species' range is central for developing its effective conservation and management plans.
