Systematics

Fish systematic research has enabled more accurate identification of species in the eastern Bering Sea and Aleutian Islands region. One of the products, "Field Guide to Sharks, Skates, and Ratfish of Alaska", will dramatically improve the species-level identifications of elasmobranchs in Alaska. Other research has included the identification of new species of skates and eelpouts.

Systematics provides data users with relative reliability guidelines of historical groundfish survey species identifications. For more information, see the species identification confidence in the eastern Bering Sea shelf surveys (1982-2008); Gulf of Alaska and Aleutian Islands surveys (1980-2011); Bering Sea slope surveys (1976-2010).
