Population data are scarce for many species of marine mammals in the Barents Sea, making it difficult to identify population trends and their underlying causes.
Hooded and harp seals are both found in the West Ice and harp seals also breed in the White Sea. The most recent estimate for the West-ice group of harps seals is ~750 000 (2008) and the population is thought to be stable or increasing.

The actual area is inhabited by 28 fish species which are either on the Global Red List (8 species), or on the Norwegian Red List (25 species). Among these 13 is DD species, i.e. no scaled evaluation can be done because of lack of knowledge, but the species would probably be on the red list if adequate information had been available.

Fisheries are meant to influence the ecosystem by removing sustainable quantities of fish as food for humans. The fishery is, however, not considered sustainable if it impairs the recruitment of the fish stocks. Single species management often focuses on measuring the status of the fishery in relation to benchmarks called biological reference points (BRPs). The harvest rate and fishing pattern sho...
