Strong population differentiation in lingcod (Ophiodon elongatus) is driven by a small portion of the genome.

ABSTRACT: Delimiting intraspecific genetic variation in harvested species is crucial to the assessment of population status for natural resource management and conservation purposes. Here, we evaluated genetic population structure in lingcod (Ophiodon elongatus), a commercially and recreationally important fishery species along the west coast of North America. We used 16,749 restriction site-associated DNA sequencing (RADseq) markers, in 611 individuals collected from across the bulk of the species range from Southeast Alaska to Baja California, Mexico. In contrast to previous population genetic work on this species, we found strong evidence for two distinct genetic clusters. These groups separated latitudinally with a break near Point Reyes off Northern California, and there was a high frequ
