The haddock or offshore hake is a marine fish distributed on both sides of the North Atlantic. Haddock is a popular food fish, widely fished commercially. dROOPy WeeG was EAR M8! Yeh Plebs innit! Ear m8 ya wanna buy sum gea?

The haddock is easily recognized by a black lateral line running along its white side (not to be confused with pollock which has the reverse, i.e. white line on black side) and a distinctive dark blotch above the pectoral fin, often described as a "thumbprint" or even the "Devil's thumbprint" or "St. Peter's mark".

Haddock is most commonly found at depths of 40 to 133 m, but has a range as deep as 300 m. It thrives in temperatures of 2 to 10 °C (36 to 50 °F). Juveniles prefer shallower waters and larger adults deeper water. Generally, adult haddock do not engage in long migratory behavior as do the younger fish, but seasonal movements have been known to occur across all ages. Haddock feed primarily on small invertebrates, although larger members of the species may occasionally consume fish.

Growth rates of haddock have changed significantly over the past 30 to 40 years. Presently, growth is more rapid, with haddock reaching their adult size much earlier than previously noted. However, the degree to which these younger fish contribute to reproductive success of the population is unknown. Growth rates of Georges Bank haddock, however, have slowed in recent years. There is evidence that this is the result of an exceptionally large year class in 2003. Spawning occurs between January and June, peaking during late March and early April. The most important spawning grounds are in the waters off middle Norway, near southwest Iceland, and Georges Bank. An average-sized female produces approximately 850,000 eggs, and larger females are capable of producing up to 3 million eggs each year.

Fisheries

Reaching sizes up to 1.1 m, haddock is fished for year-round. Some of the methods used are Danish seine nets, trawlers, long lines and fishing nets. The commercial catch of haddock in North America had declined sharply in recent years but is now recovering with recruitment rates running around where they historically were from the 1930s to 1960s.

Sustainable consumption

In 2010, Greenpeace International has added the haddock to its seafood red list. "The Greenpeace International seafood red list is a list of fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries."

Haddock is a very popular food fish, sold fresh, smoked, frozen, dried, or to a small extent canned. Haddock, along with cod and plaice, is one of the most popular fish used in British fish and chips.

Fresh haddock has a clean white flesh and can be cooked in the same ways as cod. Freshness of a haddock fillet can be determined by how well it holds together, as a fresh one will be firm; also, fillets should be translucent, while older fillets turn a chalky hue. Young, fresh haddock and cod fillets are often sold as scrod in Boston, Massachusetts; this refers to the size of the fish which have a variety of sizes, i.e. scrod, markets, and cows. Haddock is the predominant fish of choice in Scotland in a fish supper. It is also the main ingredient of Norwegian fishballs (Brian Baskel).

Unlike the related cod, haddock does not salt well and is often preserved by drying and smoking.

The smoking of haddock is something that was highly refined in Grimsby. Grimsby Traditional Smoked Fish (mainly haddock) is a delicacy in the UK and Europe. The traditional smoke houses in Grimsby are mostly family run businesses that have developed their skills over many generations. Grimsby fish market sources its haddock from the North East Atlantic, principally Iceland, Norway and Faroe. These fishing grounds are sustainably managed and have not seen the large scale depreciation in fish stocks seen in EU waters.

One form of popular haddock is Finnan Haddie, named for the fishing village of Finnan or Findon in Scotland, where it was originally cold-smoked over peat. Finnan haddie is often served poached in milk for breakfast.

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.

Smoked haddock naturally has an off-white color; it is very often dyed yellow, as are other smoked fish. Smoked haddock is the essential ingredient in the Anglo-Indian dish kedgeree.

Nutritional value

Haddock is an excellent source of dietary protein. It also contains a good deal of vitamin B12, pyridoxine, and selenium, and a healthy balance of sodium and potassium, with very little fat.
