HADDOCK

(Melanogrammus aeglefinus), valuable North Atlantic food fish of the cod family, Gadidae, that is often smoked and sold as finnan haddie. The haddock is a bottom dweller and a carnivore, feeding on invertebrates and some fishes. It resembles the cod and, like its relative, has a chin barbel and two anal and three dorsal fins. It is identified, however, by a dark, rather than light, lateral line and a distinctive dark spot on each shoulder. Colour is otherwise gray or brownish above, paler below. Size is to about 90 centimetres (3 feet) and 11 kilograms (24 1/2 pounds).
