Genetic diversity and population structure of the blue jack mackerel Trachurus picturatus across its western distribution
Blue jack mackerel Trachurus picturatus collected at six sampling locations of the north‐east Atlantic Ocean (Azores, Madeira, Canaries, and Matosinhos, Peniche and Portimão, mainland Portugal) and one location in the Mediterranean (Sicily), were used to examine the genetic structure of this species...
