| Abstract |
The genetic population structure of the blue whiting (Micromesistius poutassou) was studied by means of enzyme electrophoresis. Most of the Eastern Atlantic distribution range of the species was covered by samples from the Barents Sea in the north to the inner Mediterranean (Greece) waters in the south-east. Genetic heterogeneity was generally low between samples from the spawning areas west of the British Isles. Inner Mediterranean blue whiting deviated somewhat genetically, and a genetic substructure on a west-east axis north of the British Isles was also indicated. However, the most striking trait in the material was the deviating gene frequencies of the blue whiting from northern Norway and the Barents Sea, which showed very significant signs of being a reproductively isolated stock. |
