Several seabird populations in the Barents Sea region are of international importance. The most numerous species are: Brünnich´s guillemot (Uria lomvia); little auk (Alle alle); Atlantic puffin (Fratercula arctica); black-legged kittiwake (Rissa tridactyla), northern fulmar (Fulmarus glacialis); and common eider (Somateria mollissima). An important part of the global breeding population of the rare ivory gull (Pagophila eburnea) is found within the northern part of the region — in Svalbard and Franz Josef Land.
The Barents Sea is inhabited by 21 species of sea mammals. Among these, 11 species are threatened according to the IUCN Red List, 13 are included in the Red Book of the Russian Federation (2001) and 8 extant species are on the endangered species list of Norway (Table 4.3.6) (plus the recently extinct northern right whale stock). Anthropogenic factors thought to be most harmful for marine mammals are fisheries interactions, pollution, and climate warming; the
The Barents Sea region is inhabited by 28 fish species which are either on the Global Red List (8 species) or on the Norwegian Red List (25 species) (Table 4.3.6). Among these, 13 are data deficient (DD) species, i.e. the species would likely appear on the red list if adequate information were available. When considering the lists of rare and threatened marine fish species, 3 main groups of impact factors may be considered: 1) fisheries (catch and by-catch); 2) environmental
