Description
The haddock has the elongated, tapering body shape typical of members of the cod family.
The upper side of the haddock's body varies in colour from dark grey brown to nearly black while the lower part of the body is dull silvery white. It has a distinctive black
The longest haddock recorded was 94 centimetres (37 inches) in length and weighed 11 kilograms (24 pounds). However, haddock are rarely over 80 cm (31+1⁄2 in) in length and the vast majority of haddocks caught in the United Kingdom measure between 30 and 70 cm (12 and 27+1⁄2 in).[9] In eastern Canada waters, haddock range in size from 38 to 69 cm (15 to 27 in) in length and 0.9 to 1.8 kg (2 lb 0 oz to 3 lb 15 oz) in weight.[8]
Distribution
The haddock has populations on either side of the north Atlantic but it is more abundant in the eastern Atlantic than it is on the North American side. In the north-east Atlantic it occurs from the
Habitat and biology
The haddock is a demersal species which occurs at depths from 10 to 450 m (33 to 1,500 ft; 5.5 to 250 fathoms), although it is most frequently recorded at 80 to 200 m (300 to 700 ft; 40 to 100 fathoms). It is found over substrates made up of rock, sand, gravel or shells and it prefers temperatures of between 4 and 10 °C (39 and 50 °F). Off Iceland and in the Barents Sea, haddock undergo extensive migrations, but in the north western Atlantic its movements are more restricted, consisting of movements to and from their spawning areas. They reach sexual maturity at 4 years old in males and 5 years old in females, except for the population in the North Sea which matures at ages of 2 years in males and 3 years in females. The overall sex ratio is roughly 1:1, but in shallower areas, females predominate, while the males show a preference for waters further offshore.[6]
The fecundity of the females varies with size: a fish of 25 cm (10 in) length bears 55,000 eggs while a fish at 91 cm (36 in) has 1,841,000 eggs. Spawning takes place from depths of around 50 to 150 m (200 to 500 ft; 30 to 80 fathoms). In the northwestern Atlantic spawning lasts from January to July, although it does not occur simultaneously in all areas, and in the northeastern Atlantic the spawning season runs from February to June, peaking in March and April.[6] The eggs are pelagic with a diameter of 1.2 to 1.7 millimetres (3⁄64 to 9⁄128 in), and they take one to three weeks to hatch. Following metamorphosis, the past larval fish remain pelagic until they attain a length of around 7 cm (3 in), when they settle to a demersal habit.[10] Their growth rate shows considerable regional variation and fish at one year old can measure 17 to 19 cm (6+1⁄2 to 7+1⁄2 in), at 2 years old 25 to 36 cm (10 to 14 in), up to 75 to 82 cm (29+1⁄2 to 32+1⁄2 in) at 13 years old. Their lifespan is around 14 years.[6] The most important spawning grounds are in the waters off the central coast of Norway, off the southwest of Iceland, and over the Georges Bank.[10][11] The fish which spawn in inshore waters are normally smaller and younger fish than those which occur in offshore areas. The younger fish have a spawning season which is less than half of that of the larger and older stock offshore. Once hatched the larvae do not appear to travel far from their spawning grounds, however some larvae spawning off the west coast of Scotland are transported into the North Sea through the Fair Isle-Shetland Gap or to the northeast of Shetland.[12]
In their larval stages, haddock mainly feed on the immature stages of
The recorded growth rates of haddock underwent significant change over the 30 to 40 years up to 2011.
Parasites
Cod and related species are plagued by parasites. For example, the
The female worm, with her now fertilized eggs, then finds a cod, or a cod-like fish such as a haddock or whiting. There, the worm clings to the gills while it metamorphoses into a plump, sinusoidal, wormlike body, with a coiled mass of egg strings at the rear. The front part of the worm's body penetrates the body of the cod until it enters the rear bulb of the host's heart. There, firmly rooted in the cod's circulatory system, the front part of the parasite develops like the branches of a tree, reaching into the main artery. In this way, the worm extracts nutrients from the cod's blood, remaining safely tucked beneath the cod's gill cover until it releases a new generation of offspring into the water.[10][13][14]

Fisheries
Haddock is fished year-round using gear such as Danish
In the western Atlantic the eastern Georges Bank haddock stock is jointly assessed on an annual basis by Canada and the United States and the stock is collaboratively managed through the Canada–United States Transboundary Management Guidance Committee, which was established in 2000. The commercial catch of haddock in North America was approximately 40–60 thousand tonnes per year between 1920 and 1960. This declined sharply in the late 1960s to between 5 and 30 thousand tonnes per year. Despite a few good years post-1970, landings have not returned to historical levels.[11]
Haddock currently resides on the Greenpeace seafood red list due to concerns regarding the impact of bottom trawls on the marine environment.[24] In contrast, Monterey Bay Aquarium considers haddock a "good alternative".[25] Many haddock fisheries have been certified as sustainable by the Marine Stewardship Council.[26] All seven stocks assessed in the eastern Atlantic are currently considered by ICES to be harvested sustainably. The haddock populations in the western Atlantic (offshore grounds of Georges Bank off New England and Nova Scotia) are also considered to be harvested sustainably.[27]

Haddock is very popular as a food fish. It is sold fresh or preserved by smoking, freezing, drying, or to a small extent canning. Haddock, along with
The smoking of haddock was highly refined in Grimsby. Traditional Grimsby smoked fish (mainly haddock, but sometimes cod) is produced in the traditional smokehouses in Grimsby, which are mostly family-run businesses that have developed their skills over many generations.[37] Grimsby fish market sources its haddock from the North East Atlantic, principally Iceland, Norway and the Faroe Islands. These fishing grounds are sustainably managed[38] and have not seen the large scale depreciation in fish stocks seen in EU waters.[39]
One popular form of haddock is Finnan haddie which is named after the fishing village of Finnan or Findon in Scotland, where the fish was originally cold-smoked over smouldering peat. Finnan haddie is often poached in milk and served for breakfast.[40][41]
The town of Arbroath on the east coast of Scotland produces the Arbroath smokie. This is a hot-smoked haddock which requires no further cooking before eating.[42]
Smoked haddock is naturally an off-white colour and it is frequently dyed yellow, as are other smoked fish. Smoked haddock is the essential ingredient in the Anglo-Indian dish kedgeree,[5] and also in the Scottish dish Cullen skink, a chowder-like soup.[43]
