The stockStock:
The fish of a particular species reproducing in the same area in the same period. of albacore tuna in these fishing areas is not being overfishedOverfished:
A stock is overfished when the stock size has decreased so far that it can no longer produce a maximum sustainable yield. The size of the fish populations is insufficient to reproduce in the long term. . The biomassBiomass:
Biomass is the mass (weight) of living organisms in an area or ecosystem at the time. of this stock is currently above sustainableSustainable:
Meeting the needs of current generations without compromising opportunities for future generations. This also allows future generations to benefit from the same needs. levels.
The tuna fishery with pelagic longlinesLonglines (drifting):
A fishing method whereby a long main line (40-100 km long) with transverse lines with hooks with bait is expanded. The line floats on buoys in the water column. most likely has a major impact on the ecosystem through 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 endangered and protected species. Although this is less of a problem for the pursePurse seines:
A ring net in which the net is circulated around a school of fish. Then the net is closed and taken in. This is also called 'purse seine'. seine fishery, there are still high bycatch rates of juvenile tuna in this fishery.
ManagementManagement:
The regulations surrounding fisheries and aquaculture that ensure that production is carried out within legal frameworks and that sustainability can be assured. of albacore tuna in the Atlantic is overseen by ICCATICCAT:
International Commission for the Conservation of Atlantic Tunas, an international fisheries organization responsible for the conservation of tuna and tuna species in the Atlantic Ocean and adjacent seas.. A lack of robust information and observations at sea pose major problems for the management of this fishery. In addition, current management [measures] are still insufficient to minimise 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). and prevent illegalIllegal fishing:
Fisheries that do not comply with the established agreements, such as not giving up catches to national authorities, operating without permission or in prohibited/closed zones. Illegal fishing is covered by IUU fishing (Illegal Unreported Unregulated). fishing. Management of this species is not effective.
