The northernmost self‐sustaining populations of European lobster (Homarus gammarus) are found north of the Arctic Circle (66°33'N), in Tysfjord and Nordfolda, two large, deep, and relatively warm fjord systems in northern Norway. In contrast to most other Norwegian lobster populations, these genetically distinct populations are still found at relative high densities. This paper presents results from surveys conducted in the fj...

The European lobster, Homarus gammarus, is a high value species, which is widely distributed from the northern part of Norway to Morocco in North Africa. It is also found throughout the Mediterranean including the Aegean Sea. Knowledge of the genetic structure is necessary for rational management of exploited species. As part of a comprehensive genetic investigation of European lobster (EU‐project “Genetics of European Lobster...
