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. is too high.
In this area, fishing with gillnetsGillnets:
A fishing technique whereby passing fish get caught in the meshes with their gills. The net stands vertically on the bottom or hangs on buoys in the water column. The by-catch of species such as porpoises and dolphins is a problem related to gillnets., 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. and 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'. seines causes 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 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. It is possible, however, that vulnerable species groups such as seabirds and marine mammals could become entangled in the nets and lines. The effects these methods have on the ecosystem are largely unknown, but do not appear to have a major impact on benthic habitats and species.
These fisheries are managed by Alaska and the North Pacific Fishery Management Council. Salmon fisheries are well managed by establishing “escapementEscapement goals:
Escapement goals are objectives used for example in the management of Pacific salmon stocks. It is determined how many salmon must escape the fishery and continue reproducing in order to exploit the stocks sustainably and with optimal yields. goals” for key salmon stocks and intensive monitoring.
