Atlantic Halibut

Atlantic halibut is one of the largest bottom-dwelling flatfish in the world, weighing up to 700 pounds (320 kg). They primarily live in northern cold waters, from the Gulf of St. Lawrence and the Barents Sea to as far south as the Bay of Biscay. Seldom entering waters of less than 200 feet (60 m) deep, halibut have a blotchy olive and brownish colour that disguises it when nestled into the sandy seafloor.

Atlantic halibut are flat and diamond-shaped with a white underbelly and both eyes on its upper side. It is a firm-textured fish and has relatively few bones, making it a popular catch. Atlantic halibut are larger but have a similar flavour to its Pacific cousin (Hippoglossus stenolepis).

Atlantic Halibut

Female halibut begin to spawn between 10 and 14 years of age. Each fish can lay up to several million pink eggs during the spawning season between December and June. The eggs float freely for about 16 days, after which they hatch into larvae with a large yolk sac. By four or five weeks, the larvae develop into juveniles and begin to feed on plankton. They grow rapidly, about three inches (7 to 8 cm) each year, until they reach sexual maturity and adopt a bottom-dwelling life. Atlantic halibut can live up to 50 years, but their typical lifespan is about 25 to 30 years.

Food Info Atlantic Halibut


  • Colour: very white
  • Texture: large flakes, a firm but tender texture and very lean
  • Flavour: fairly mild with a distinctive sweetness
  • Perfect serve: Its thick, succulent meat holds together perfectly when battered for traditional fish and chips, while its distinctive sweet flavour holds its own against the richness of this dish.

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 Halibut by Longline (NAFO 3Pn)>, <License: Atlantic Halibut by Longline (NAFO 3Ps)>, <License: Atlantic Halibut by Longline (NAFO 4R)>], 'gear': <Gear: Small-Boat Longline with Hooks>}

Small-Boat 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.

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 Halibut 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.
