The ferocious-looking wolffish gets its name from the sharp, protruding teeth it uses to feast on lobsters, clams and other shellfish. Found from southern New England to Greenland and the Barents Sea, the bottom-dwelling coldwater creature is primarily a bycatch of trawl fisheries targeting cod, haddock and other groundfish. Iceland, which has a directed fishery for the species, is the largest producer. Imports also come from Canada and Norway, which is developing wolffish-farming  operations. The striped wolffish is one of three Atlantic species, which also include the northern (A. denticulatus) and the spotted (A. minor) wolffish. From a culinary standpoint, there’s little difference among the three. Wolffish can reach 30 or 40 pounds, but market size averages 10 pounds.
