Intraspecific diversity is central to the management and conservation of exploited species, yet knowledge of how this diversity is distributed and maintained in the genome of many marine species is lacking.

Here, we analyzed genome-wide polymorphisms to measure genetic differentiation between an offshore migratory and a non-migratory population and to define conservation units of Atlantic Cod (Gadus morhua) in coastal Labrador.
