Genetic structure of whiting Merlangius merlangus in the northeast Atlantic and adjacent waters
International audience Accurate identification of stock boundaries is essential for efficient fisheries management; hence, the present study focused on the genetic structure of whiting. To this aim, 488 individuals collected from the southern Bay of Biscay to the southern Norwegian coast were genoty...
