Atlantic wolffish

Atlantic wolffish, Atlantic catfish, seawolf, or devil fish, is a unique-looking fish with a large head and big frontal teeth. Their rear teeth are adjusted to be able to crack hard materials like crab shells and larger species of mollusc. Atlantic wolffish have a dark blue-greyish or greenish colour and can grow up to 1.5 m in length and can reach 22 years of age. This species is native to the northern part of the Atlantic Ocean and can be found on rocky, sandy, or muddy seabed’s at depths of up to 500 metres. Atlantic wolfish is gaining in popularity among consumers and is appearing increasingly on restaurant menus.

Explanation assessment

The stock of Atlantic wolffish is at sustainable levels. The biomassBiomass:
Biomass is the mass (weight) of living organisms in an area or ecosystem at the time.
of this species is increasing and the fishing pressureFishing pressure:
Fishing pressure is a result of the fishing effort/amount of fishing on a stock, which determines the fishing mortality. Fishing mortality is the share of the fish stock that dies annually as a result of fishing.
remains within biologically safe limits.

Demersal fisheries, such as bottomBottom trawls:
A fishing technique in which cone-shaped nets terminating in a codend are dragged through the water column or along the bottom.
trawls, anchoredanchored gillnets:
A fishing technique whereby passing fish become tangled up in a net with their gills (also known as a gillnet), which is vertically standing on the bottom.
gillnets, demersalDemersal otter trawls:
A technique in which conical nets are dragged over the ground and are held open by large, square 'otter planks'. The planks also work as a plough, in which fish are hunted into the nets.
longlines and DanishDanish seines:
A fishing technique whereby one of the lines of the seine net/pit net is anchored. The ship expands the net with a moving motion and turns off when picking up the net.
seines can impact the ecosystem by coming into contact with benthic habitats and species. Currently, there is insufficient information on the effects of these fisheries on the Atlantic wolffish itself, as on other (bycatchBycatch:
Species caught next to species targeted for fishery. By-catches can consist of non-commercial species and species that are too small, and can be kept (this part is sometimes called by-product) or thrown back into the sea (discards).
