Population genetic studies of northern shrimp, Pandalus borealis, in Icelandic waters and the Denmark Strait
The aim of this study was to describe the population structure of northern shrimp, Pandalus borealis, in Icelandic waters and the Denmark Strait, based on genetically determined and electrophoretically detectable protein variants. Muscle samples of 4417 specimens were collected from 24 sampling loca...
