Recorded distribution in Britain and IrelandFound throughout British and Irish waters but more common off the north-eastern Scotland, north-east England, south-western England and the Irish sea.
HabitatThe common haddock is a demersal species and shoals in colder waters at depths of 40-300 m. It can be found over rock, sand, gravel or shells.
- Dark uninterrupted lateral line.
- Three dorsal fins, two anal fins.
- Dark spot below first dorsal fins.
- First dorsal fin is high, triangular and has a concave trailing margin.
- Short and rounded nose and big eyes.
- Small mouth, not gaping back to below the eye.
Additional informationMelanogrammus aeglefinus is a valuable species that is exploited commercially in mixed trawl and seine fisheries, along with cod (Gadus morhua) and whiting (Merlangius merlangus), and is a bycatch in Norway lobster (Nephrops norvegicus) fisheries (Hedger et al., 2004). Spawning takes place from March to May, at depths of 100-150 m (Alekseeva & Tormosova, 1979). The easiest ways to tell a haddock from a cod (Gadus morhua) are by the dark colouring of the lateral line and the presence of a dusky blotch just below either of the first dorsal fins.
