Identification and Quantification in Food

Stomach contents data were used to investigate spatial, seasonal and inter-annual patterns of feeding of the thorny skate (Amblyraja radiata) in the Barents Sea during 1994-2000.The diets and food consumption by the thorny skate of different size groups were analyzed and assessed with special reference to the consumption of commercial species of fishes and crustaceans.Less comprehensive data on food composition are presented for other less abundant Barents Sea skates: arctic skate (A.hyperborea), round skate (Rajella fyllae), blue skate (Dipturus batis), spinytail skate (Bathyraja spinicauda) and sail ray (D. linteus).
