In this study we compared seasonal and regional variation in the diet of harbour seals ( Phoca vitulina ) and great cormorants ( Phalacrocorax carbo ) in the semi-closed water system in Limfjord, northwest Denmark.

Description
Summary:In this study we compared seasonal and regional variation in the diet of harbour seals ( Phoca vitulina ) and great cormorants ( Phalacrocorax carbo ) in the semi-closed water system in Limfjord, northwest Denmark. To compare with an open-water system containing similar prey species, we also analysed harbour seal diet from the western Baltic (Figure 1). In total 119 harbour seal scats, 17 harbour seal digestive tracts and 198 great cormorant casts were investigated.
