They range from Canada to North Carolina and feed on fish and other creatures found near the sea floor. The fish is carnivorous, with its prey consisting mainly of benthic invertebrates and fishes. In most cases, the barndoor skate is not intentionally harvested by the commercial fishing industry—it is usually considered bycatch in the trawling nets used to target other species of fish. Barndoor skate (Dipturus laevis) is one of the largest skate species in the Northwest Atlantic, and seasonal trawl surveys have identified Georges Bank as critical barndoor skate habitat. Like most skates and rays, they live on the seafloor, where they hunt a variety of invertebrate and fish prey. The barndoor skate Dipturus laevis (Mitchill 1817), is one of many skate and ray species caught as bycatch in finfish trawl and scallop dredges in the Northwest Atlantic. It is a bottom dwelling species mainly found at depths of 100–200 m (330–660 ft), but it can occur as shallow as 30 m (98 ft) and as deep as 1,000 m (3,300 ft). The present study will provide vital information concerning the trophic role of the Barndoor Skate and will assist in the designation of essential fish habitat, which is defined legally as “those waters and substrate necessary to fish spawning, breeding, feeding, or growth to maturity (16 U.S.C.
