In the Aleutian Islands ecosystem, food habits of many noncommercial species such as skates have not been studied. This study provides the basic information on food habits and diet overlap of 7 skate species found in the Aleutian Islands area. These species include the Aleutian skate (Bathyraja aleutica), big skate (Raja binoculata), Bering skate (B. interrupta), Alaska skate (B. parmifera), black skate (B. trachura), mud skate (B. taranetzi), and whiteblotched skate (B. maculata). Small skates (black skates, Bering skates, and mud skates)ate mainly polychaetes, mysids, isopods, and gammarid amphipods.Larger skates (big skates, Aleutian skates, whiteblotched skates,and Alaska skates) fed primarily on Atka mackerel, walleyepollock, other miscellaneous fish, crabs, and shrimp.
