Genetic differentiation between inshore and offshore populations of northern shrimp ( Pandalus borealis)
Abstract Many marine organisms have a permanent presence both inshore and offshore and spawn in multiple areas, yet their status as separate populations or stocks remain unclear. This is the situation for the northern shrimp (Pandalus borealis) around the Arctic Ocean, which in northern Norway repre...
