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).

Spawning occurs in winter and beginning of spring, where big schools are formed. Spawning sites are in offshore waters, at or near the bottom, in 50-200 m depth and 0-12 °C (preferred range 0-6°C) (Refs. 1371, 89387). May form spawning aggregations in the water column when bottom temperatures are unsuitable (Ref. 1371). Different spawning areas may be used in subsequent years (Ref. 89387). Embryo development lasts about 14 days (at 6°C) and larval phase lasts about 3 months(at 8°C). Fecundity ranges from 2.5 million eggs in a 5 kg female to a record of 9 million eggs in a 34 kg female. Reported number of batches spawned in an experiment is 8 - 22 (Ref. 5513). Sex ratio is nearly 50%, with slight predominance of females. Classified as a determinate multiple spawner (Ref. 40290). Older and larger cod had been found to produce larger eggs with neutral buoyancy at lower salinities. This can be crucial to egg and larval survival (Refs. 31930, 38384). Larvae are pelagic up to 2.5 months before settling on the bottom (Ref. 1371). In the Baltic, spawning cumulates in March at depths below 20 m near the bottom. The nursery areas are in the inner coastal zone. Recruitment to the fished stock starts below 2 years and peaks at about 3 years of age (Ref. 5947).北大西洋: 到 Ungava 海灣的岬 Hatteras 沿著北美海岸; 東方與格陵蘭的西岸; 冰島的周圍; 歐洲從比斯開灣到巴倫支海的海岸, 包括區域在有島周圍。
