Chinook salmon stockStock:
The fish of a particular species reproducing in the same area in the same period. s are not doing well. They are currently at low levels and populations are showing declines. Stock estimateStock estimate:
Estimating the number of fish of a particular species who are reproducing in the same spawning area in the same period. s take place with high uncertainties, so 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. cannot be properly determined.
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 are unlikely to have a major impact on threatened 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. This fishery is very selectiveSelective fishing methods:
Selective fishing methods capture many target species, and little or no unwanted fish species and animals. , but may have 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 salmon species that occur here. These are often treated as discardsDiscards:
Unwanted by-catch, which is thrown back because there is no quota, the market price is too low, or the fish is below the legal minimum landing size. Discards can be alive or dead..
Chinook fisheries are managed by the Pacific Salmon Treaty and Canada’s Policy for conservation of Wild Pacific Salmon. Management is conducted from an ecological perspective, taking into account the functioning of the entire ecosystem. 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.
