| Order: | Gadiformes | |||
| Class: | Teleostei | |||
| English name: | Atlantic cod | |||
| Distribution: | North Atlantic and Arctic: Ungava Bay in Canada along the North American coast to Cape Hatteras; North Carolina in the western Atlantic. East and west coast of Greenland; around Iceland; from Barents Sea including the region around Bear Island along the European coast to Bay of Biscay (Ref. 88171). | |||
| Adult biology: | Widely distributed in a variety of habitats, from the shoreline down to the continental shelf. Juveniles prefer shallow (less than 10-30 m depth) sublittoral waters with complex habitats, such as seagrass beds, areas with gravel, rocks, or boulder, which provide protection from predators (Refs. 89383, 89384). Adults are usually found in deeper, colder waters. During the day, form schools and swim about 30-80 m above the bottom, dispersing at night to feed (Ref. 1371, 89385). Omnivorous; feed at dawn or dusk on invertebrates and fish, including young cod. (Ref. 1371). Migrate between spawning, feeding and overwintering areas, mostly within the boundaries of the respective stocks. Migrations >200 km are rare occurrences (Refs. 89386, 89387). Marketed fresh, dried or salted, smoked and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). | |||
| Diagnosis: | Yolk sac absorbed at about 4.5 mm (Ref. 7135). Lancet-shaped base of caudal fin. 1 to 3 ventral caudal melanophores. The ventral row of melanophores generally extends farther back than the dorsal (in contrast to G. virens) (Ref. 37). Pelvic fins thoracic, elongate; no head spines present during larval development (Ref. 68). Young 15.0 to 30.0 mm recognizable by vent under 2nd dorsal fin and dense pigmentation. Pigmentation: pigment patterns usually well-developed at hatching (Ref. 68). At 7.0 to 10.0 mm, pigment bars fuse and a median band forms. At 10.0 to 20.0 mm, pigment extends to the tail. Sequence of fin formation: At 20.0 mm, dorsal and anal fins have full complement of rays.. See also LARVAE table. | |||
