Food Habits and Diet Overlap of Seven Skate Species in the Aleutian Islands
نویسنده
چکیده
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, walleye pollock, other miscellaneous fish, crabs, and shrimp.

Catches and exports of skate Rioraja agassizii place this species as "vulnerable to extinction" on the IUCN Red List; therefore, biological and ecological knowledge becomes an important instrument for its conservation control. This study described and quantified the diet composition of R. agassizii by means of stomach analysis contents in the periods 2005-2006 and 2012-2013. We analyzed and qua...
