Most pink salmonstockStock:
The fish of a particular species reproducing in the same area in the same period. s are healthy. However, the 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 are made with high uncertainties. It appears that some stocks are 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. or stock sizes are not yet known.
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. and fykesfykes:
A fishing technique where fish are attracted into a fyke. Fykes are pots or traps made of, for example, wire mesh. can entangle vulnerable seabirds, whales and dolphins. The effects these methods have on the ecosystem are largely still unknown, but do not appear to have a major impact on benthic habitats and species.
The salmon fisheries in this area are managed, but information on the stockStock:
The fish of a particular species reproducing in the same area in the same period. s and how measures are adhered to is still insufficient. The 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.
