The short life span and environmental dependence of the brown shrimp makes for a highly variable stockStock:
The fish of a particular species reproducing in the same area in the same period. . This makes it difficult to carry out conventional stock estimates.
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 and beamBeam trawls:
A technique in which a pit net at the top is kept open by a horizontal tube (the tree). Ticklerchains are tossed through the bottom to hunt the fish into the net. trawls can have a major negative impact on the ecosystem as they are dragged across the seabed. 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, including endangered and protectedProtected species:
Many marine species are protected from deliberate or intentional disturbance, capture, injury and killing, and in some cases possession or sale. Species are often protected if they play an important role in the ecosystem or are sensitive to fishing. These marine species are protected regardless of whether they are inside or outside marine protected areas. species, is likely and often documented.
Brown shrimp is managed through a so-called HarvestHarvest Control Rule:
Harvest control rules (HCRs) are the operational component of a harvest strategy, essentially pre-agreed guidelines that determine how much fishing can take, based on indicators of the targeted stock's status. Control Rule, which limits the level of fishing effort. The EU has not set catch limitsCatch limits:
The maximum amount of fish of a species caught per country, per year. . 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 partially effective.
