Scod, Finnan Haddock


Haddock is a North Atlantic white fish with a very distinctive black blotch—known as the “Devil’s thumbprint”—just above the pectoral fin and an easily recognizable black lateral line running down its side. This deep-sea fish, typically weighing from 2 to 7 pounds (1 to 3 kg), is prolific along the coasts of both North America and Europe.

Haddock have a purplish-grey coloured head and back that gives way to silvery grey with a pinkish tinge and a white belly. It is an elongated fish with a forked tail and three dorsal fins. It is a lean, firm white fish that is popular smoked and in fish and chips.


A highly fecund species, haddock live most of their life in deep waters between 130 and 1,000 feet (40 and 300 m). A female’s production of eggs increases substantially with age, from a few hundred thousand in the youngest spawners to three million in the oldest. Once spawning occurs, the eggs are pelagic – living on the surface of the ocean. Larvae generally float freely for around three months before descending to the bottom to live with the rest of their kind. Spawning occurs between January and June, peaking during late March and early April. The average lifespan for haddock lies somewhere between three and seven years of age, with males generally reaching maturity at four years and females at five. Haddock feed mainly on shellfish, sea urchins, worms, and small fish like sand eels and capelin. In Canada, the most important haddock stocks live from the Bay of Fundy to Cape Breton and the Grand Banks. 

Food Info Haddock


  • Colour: bright white.
  • Texture: remarkably firm yet fine, with delicate lean flakes
  • Flavour: Delicate, mild, yet slightly sweet in flavour.
  • Perfect serve: Haddock is the perfect fish when smoked for flaking into dishes such as the traditional Anglo-Indian kedgeree. Often served up for breakfast, kedgeree is made on the stove top by combining flaked smoked haddock, boiled rice, parsley, hard boiled eggs, curry powder and cream. Another popular breakfast dish uses smoked “Finnan Haddie” (named for the fishing village of Finnan in Scotland where it was originally cold-smoked over peat), which is then poached in milk.

These crabs mate at the time of maturity, which is approximately 3 years of age. Females are smaller than males; this is because the development of reproductive tissues required more energy for females, leaving less energy available for continued body growth. They grow through a process known as molting—regularly shedding their shell and growing a new, larger one. They continue to molt and grow after they have reached sexual maturity. During the breeding season, the crabs leave their borrows in a phenomenon characterized by mass mate-searching events. Once mating/fertilization has occurred, females spawns in the water. The larvae released during the rainy season develop in offshore waters and return to coastal waters five to eight weeks after larval release.
Mangrove crabs are important fishery resources in all Brazilian coast, mainly in the north and northeast where many fishermen depend upon their catch. In addition to its social and economic importance, the mangrove crab is a “keystone” species in ecosystem, they playing an important role in the processes of nutrient cycling and energy transfer.

Fishing Methods

{'fisheries': [<License: Haddock by Hook & Line>], 'gear': <Gear: Bottom Longline with Hooks>}

Bottom Longline with Hooks

This fishery uses a bottom longline that is baited with hooks and anchored to the ocean floor. A longline can be from 1 to 3 miles (1.6 to 5 km) long and have up to 2,000 hooks.


{'fisheries': [<License: Haddock by Bottom Trawl>], 'gear': <Gear: Bottom Trawl>}

Bottom Trawl

This fishery uses a large cone-shaped net that is dragged along the seafloor to catch fish. As the net is towed at low speed, hydrodynamic forces push two "otter boards" outwards opening the mouth of the net and capturing fish in its path.
