The snow crab is native to waters in Alaska, the east coast of Canada and west of Greenland, and is therefore an invasive species in the Barents Sea. Throughout 2008, new recordings of this crab have been done in the western part of the Barents Sea, and it seems that this species will achieve a more northerly distribution than the red king crab.

The preferred prey stocks of seabirds have undergone large variations the last decades, either because of overfishing or other variation in the ecosystem. The variation in capelin biomass is for example described above. These large fluctuations have had consequences for some species resulting in either serious declines in e.g. common guillemot, Brünnich’s guillemot and puffin breeding populations,...

Marine bioprospecting is defined as systematic search for interesting and unique genes, molecules and organisms from the marine environment with features that may be of value for commercial development. The high biodiversity of the oceans represents a correspondingly rich source of chemical diversity. Marine natural products identified by bioprospecting could have potential as new drugs, industria...

For several centuries, fishing have played an important role in the function and dynamics of the Barents Sea ecosystem. In early periods fisheries were purely coastal and had limited effects on the ecosystem. With the development of offshore fisheries the impact on fish stocks and the ecosystem increased rapidly. At present, large-scale fisheries are one of the main factors determining th...
