Marmamers I'm pleased to announce a new paper that I've just had published in Biology Letters:
Marine mammals' influence on ecosystem processes affecting fisheries in the Barents Sea is trivial. The abstract: 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 between cod, *Gadus morhua*, herring, *Clupea harengus*, capelin, *Mallotus* *villosus *and northern minke whales, *Balaenoptera acutorostrata*. Adding harp seals *Phoca groenlandica* into this top-down modelling approach resulted in unrealistic model outputs. Another set of models of the Barents Sea fish–fisheries system focused on interactions within and between the three fish populations, fisheries and climate. These model key processes of the system successfully. Continuing calls to support the SBS models despite their failure suggest a belief that marine mammal predation must be a problem for fisheries. The best available scientific evidence provides no justification for marine mammal culls as a primary component of an ecosystem-based approach to managing the fisheries of the Barents Sea. If you have access to Biology Letters, the pdf is available for download at: http://journals.royalsociety.org/content/n510636417643267/ If not, email me at: [email protected] and I'll send one your way.
