Abstract/Summary:
Bioenergetics and feeding ecology of Arctic cod (Boreogadus saida) were studied at low ambient temperatures, close to 0;Maximum daily rations for Arctic cod were low both for juvenile (99-168 mg ;The key role of Arctic cod in the high arctic marine food web, as the dominant prey of several seabird and marine mammal species, is predominately a result of their high standing biomass, which subsequently leads to high annual production despite the slow growth of individual fish.;Arctic cod spent relatively little energy for maintenance at low temperatures, although oxygen consumption rates (VO...
