Novel signals of adaptive genetic variation in northwestern Atlantic cod revealed by whole-genome sequencing.

ABSTRACT: Selection can create complex patterns of adaptive differentiation among populations in the wild that may be relevant to management. Atlantic cod in the Northwest Atlantic are at a fraction of their historical abundance and a lack of recovery within the Gulf of Maine has created concern regarding the misalignment of fisheries management structures with biological population structure. To address this and investigate genome-wide patterns of variation, we used low-coverage sequencing to perform a region-wide, whole-genome analysis of fine-scale population structure. We sequenced 306 individuals from 20 sampling locations in U.S. and Canadian waters, including the major spawning aggregations in the Gulf of Maine in addition to spawning aggregations from Georges Bank, southern New England, the
