The stockStock:
The fish of a particular species reproducing in the same area in the same period. 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 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 longline:
A fishing method whereby an anchored long main line (40-100 km long) is expanded, with attached transverse lines with hooks with bait. 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 affect the ecosystem by interacting with benthic habitats and species. While much is still unknown about the impact of these fisheries on the Atlantic wolffish itself, these fisheries have relatively little 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). of other species.
These fisheries are regulated by catch limitsCatch limits:
The maximum amount of fish of a species caught per country, per year. and the implementation of ecosystem-based management is monitored. Management in Iceland is considered very effective, in which a landing obligation with adequate monitoring is central. The managementManagement:
The regulations surrounding fisheries and aquaculture that ensure that production is carried out within legal frameworks and that sustainability can be assured. of this species is largely effective.
