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.
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. can entangle vulnerable seabirds, whales and dolphins. The effects this method has on the ecosystem are largely unknown, but do not appear to have a major impact on benthic habitats and species.
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.
