Genome-wide SNP based population structure in European hake reveals the need for harmonizing biological and management units
7 pages, 2 tables, 3 figures Despite its economic importance, the population structure of the European hake, Merluccius merluccius, is unresolved, and the species is assessed based on two stocks (northern and southern) separated by the Capbreton Canyon. In order to shed light into the European hake...
