Atlantic Pollock

Atlantic Pollock are related to cod and haddock, but differ in appearance from others in the cod family by having a pointed snout, a projecting lower jaw, and a forked rather than square tail. This deep-sea fish, typically weighing from 2 to 15 pounds (1 to 7 kg), is prolific along the coasts of both North America and Europe.

Pollock have a brownish-green back that fades to yellow-grey and then silver-grey on its belly. It can be identified by a small barbell that extends from the chin of the fish to its whiskers. It has a fairly elongated and rather thin body, three dorsal fins and big eyes. Considered a strongly flavoured whitefish, it is commonly used to make fish and chips and imitation crab.

Atlantic Pollock

Atlantic Pollock can live up to 25 years of age, reaching sexual maturity between 4 and 7 years. Once sexually mature, Pollock spawn when their surrounding waters cool to around 8˚C. This temperature gauge means that spawning time is more variable in its northern than southern range. On Canada’s Scotian Shelf spawning occurs from September to April and peaks from December to February. Atlantic Pollock spawn over hard, stony or rocky bottoms. The eggs rise up into the water column after being fertilized Juvenile fish live in inshore sub-tidal and intertidal zones for more than a year. At around two years of age, juveniles move to deeper water. Adults finally move even further offshore, inhabiting even deeper waters in spring and summer than in winter. 

Food Info Atlantic Pollock


  • Colour: Blue-grey fillets that turn white when cooked.
  • Texture: Firm, coarse flakes
  • Flavour: a strong flavour with high oil content for a whitefish
  • Perfect serve: The flakiness and thickness of Atlantic Pollock fillets make this fish ideal for addition to spicy, rich and creamy sauces. Thai cooking in particular favours Atlantic Pollock: try combining roughly chopped fillets with prawns cooked in a coconut curry sauce and served with jasmine rice.

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: Atlantic Pollock by Bottom Gillnet>], 'gear': <Gear: Bottom Gillnet>}

Bottom Gillnet

Fish harvesters use curtains of netting suspended by a system of floats and weights to anchor gillnets to the seafloor. The fine netting is almost invisible, so the fish unwittingly swim into the mesh.


{'fisheries': [<License: Incidental Catch 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: Atlantic Pollock by Electric Jig>], 'gear': <Gear: Electric Jig>}

Electric Jig

This hook-and-line fishing method uses a monofilament line and lures that is lowered and raised with an electric motor and pulleys, simulating the motion of hand-jigging
