Marine mammals' influence on ecosystem processes affecting fisheries in the Barents Sea is trivial
Some interpretations of ecosystem-based fishery management include culling marine mammals as an integral component. The current Norwegian policy on marine mammal management is one example. Scientific support for this policy includes the Scenario Barents Sea (SBS) models. These modelled interactions...
