Diets of spotted spiny dogfish, Squalus suckleyi, in Marmot Bay, Gulf of Alaska, between 2006 and 2014
Abstract
Diet of the spotted spiny dogfish, Squalus suckleyi, in Marmot Bay, Gulf of Alaska was studied from small-mesh surveys and large-mesh surveys conducted by Alaska Department of Fish and Game and the National Marine Fisheries Service between 2006 and 2014. A total of 333 spotted spiny dogfish stomachs were analyzed. By weight, the diet consisted mainly of Teleostei, and Cephalopoda. A total of 13 species of Teleostei were identified. The most frequently occurring fish taxa were walleye pollock (Gadus chalcogramma), capelin (Mallotus villosus), Pacific herring (Clupea pallasi), and eulachon (Thaleichthys pacificus). Euphausiids and pandalid shrimp were the most frequently occurring invertebrates.
