Sockeye salmon

Several fisheries on sockeye salmon have been MSC-certifiedMSC Certified:
Fisheries that comply with the Marine Stewardship Council assessment criteria and are certified. Fish products with the blue MSC label are caught by sustainable fisheries.; in Alaska, Canada and Russia. These use many different catching methods, including the ‘fish wheel’ which is a watermill like structure with nets attached to it that catch fish from the stream, after which they are collected in a tank. The Pacific salmon fishery is well regulated and the methods do little damage to the environment.

The Sockeye salmon [stocks] in Alaska are doing well.

Catching Sockeye salmon with [purse seine] or gillnets has 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 protected or undersizedUndersized fish:
Fish smaller than a prescribed minimum size. These sizes are determined per species and per country. For Europe, a minimum landing size applies to all EU Member States.  fish species. There are also little discards. These methods have little to no effect on the seabed. What the effect is of supplying the stock with farmed salmon is unknown.

The management in Alaska is well done by determining [escapement goals] for the most important stocks by intensive monitoring. The most critical points in the salmon fishery are well managed.

Sockeye salmon is only a small part of the salmon fishery in Russia, and is mainly 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).  in the Chum and Pink salmon fishery. The Sockeye stockStock:
The fish of a particular species reproducing in the same area in the same period.  is doing well.

Fykes have generally little negative effects on vulnerable species. The size of the negative impact of the fyke fishery on the endangered Taimen salmon is unclear, but a negative effect is expected. Fish that are bycatch in the fyke can often be discarded with a high survivability.

The management of this salmon is partially effective.

The sockeye salmon stock in Canada / British Columbia is in a bad state. Some sockeye salmon stocks are on the IUCN red list of endangered species. A part of the stock is knowingly not fished, so the salmon get time to reproduce. How large this part needs to be for a sustainable salmon stock is determined in so called ‘escapement goals’. These goals are often not met because there still is more salmon caught. The effects of the fishery on vulnerable salmon stocks is still unknown. There are measures in making to reduce the fishing pressure on salmon. Sockeye is mainly fished with gillnets, seines and hooks and lines. These methods can have different effects on the ecosystem. With hooks and lines there is bycatch of bottom fish. This bycatch is often landed. Fishing with gillnets and seines have relatively little bycatch of protected or undersized fish. These methods also don’t disturb the seabed. The effects of supplying the the salmon stock with farmed salmon are unknown. The disappearing of salmon has large effects on the nutrient supply of fresh water ecosystems.

[Driftnets] are a danger for vulnerable sea birds, dolphins and whales. It is estimated that there is a lot of bycatchBycatch:

IUUIUU:
Illegal, Unreported and Unregulated fishing.  (Illegal, Unreported, and Unregulated) fishing is a large problem in this fishery. Catches are not or wrongly reported to the authorities. The management of this species is not effective.

The catching method of 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. has as disadvantage that birds get entangled in them. Bycatch and discardsDiscards:

Discards can be alive or dead. are low and gillnets don’t disrupt the seabed. It is however known that there is bycatch of the protected taimen salmon.
