Diet of Ringed Seals (Phoca Hispida) in a Fjord of West Svalbard
Stomachs of 134 ringed seals from West Svalbard (Kongsfjorden) and East Svalbard (drift ice) were examined. Twenty-four prey taxa were found. The most important items were arctic cod (Boreogadus saida), shrimp (Pandalus borealis), krill (Thysanoessa inermis) and the amphipod Themisto libellula. In s...
