Salmonids

There are many species that belong to the Salmonids or (Protacanthopterygii). Did you know trouts, smelts, and even pikes belong to the Salmon family? Salmonids occur in either salt and freshwater. Most species are well-specialized predators and live in temperate climate zones.  Salmonids are ray-finned fishes and can be distinguished by the ‘fat-fin’ between the backfin and tail. They do not have spikes and the pelvic and pectoral fin are separated.

Salmonids are sold farmed and wildcaught. Wildcaught salmon comes from the Pacific. Almost all Atlantic salmon on sold is farmed. Since the 90s the farming of salmon increased dramatically. Norway, chile, Scotland, Canada and the Faroe islands are important farming countries for salmon. In both, wild-caught and farmed salmon problems in sustainability are prevalent.

 

 

 

Coho salmon

The coho salmon can mainly be found in coastal waters. The distribution of the coho salmon ranges from Alaska to California in the east and from Siberia to Japan and northwest China in the west. The coho salmon can reach an average length of 70 cm and can weigh 3.2-5 kilograms. Zalmen zijn zogenaamde anadrome vissen. Dit betekent dat ze geboren worden in zoetwater en vervolgens naar zee trekken, waar ze verder opgroeien. Na 1-8 jaar keren de volwassen zalmen weer terug naar het zoete water om zich voort te planten. Zalmen planten zich maar één keer voort en sterven kort na de voortplanting.

Explanation assessment

Several cohozalm fisheries are [MSC Certified msc-certified], all in Alaska. These use many different fishing methods, including the “fishing wheel” a row of nets that rotate in the flow, thus creating the fish from the stream, after which they fall into a catchment. Pacific salmon fishing is well regulated and the methods make little damage to nature.

A number of Russian cohozalm fisheries are in the MSC assessment range

Explanation assessment

Most stocks of coho salmon in Alaska are doing well.

These fishing methods pose no danger to protected species and there are 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). 
and 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.
. The seabed is not disrupted by the pelagic fishery. The effects of releasing young salmon on the ecosystem are still unknown. The disappearing of salmon will have a big impact of the nutrient supply of freshwater ecosystems.

The coho salmon fishery is well managed by determining escapement goals for the most important salmon stocks.

The catch of Coho salmon is only a small part of the Russian salmon fishery. Coho salmon is mostly bycatch from the fisheries on Chum and pink salmon. There are no data available on this fishery, therefore the impact of this fishery on the Coho salmon stock cannot be assessed.

The fishing with [fykes] has generally few negative effects on vulnerable species, only the bycatchBycatch:

The management is largely effective.

The coho salmon stocks in British-Columbia are very small.

The effect of this fishery on vulnerable salmon stocks is unknown. There are measures being made to decrease the fishing pressure on salmon. The effects of releasing young salmon on the ecosystem are still unknown. The disappearing of salmon will have a big impact of the nutrient supply of freshwater ecosystems.

The coho salmon fishery is well managed by determining escapement goals for the most important salmon stocks, and intensive monitoring.

 

De Coho [zalmbestanden bestand] in Brits-Colombia zijn erg klein.

Het effect van vissen met [zegens] op bedreigde zalmbestanden is niet bekend. Maatregelen om de [visserijdruk] te verminderen zijn momenteel in de maak. Wat de effecten zijn op het ecosysteem van het loslaten van jonge zalm is nog onbekend. Het verdwijnen van zalm heeft zal grote effecten hebben voor de [nutriëntentoevoer nutrienten] van zoetwaterecosystemen.

De zalmvisserij wordt goed beheerd door het vaststellen van [“escapement goals” escapement-goals] voor de belangrijkste zalmbestanden en door intensieve monitoring.

The catch of Coho salmon is only a small part of the Russian salmon fishery. Coho salmon is mostly bycatch from the fisheries on Chum and pink salmon. There are no data available on this fishery, therefore the impact of this fishery on the Coho salmon stock cannot be assessed.

[Driftnets] are a hazard for vulnerable seabirds, dolphins and whales. It is estimated that there are a lot of bycatch and discards in this fishery, but unfortunately there are no trustworthy data on this.

Illegal, Unreported and Unreported (IUU) fishery is also a big problem. Catches are not or falsely reported to the authorities. The management on this fishery is not effective.

 

ASC label

Fish with the ASC label is farmed in a sustainable manner.

MSC label

Fish with the MSC label is caught sustainably.

Good fish

This fish is not being overfished or is being responsibly farmed, with minimal impact on the environment.

Second choice

This fish is a second choice. There are still some improvements to be made in this fishery or fish farm.

Avoid

Do not buy this fish. It's being overfished or the way it's farmed or caught has a negative impact on the environment.

By-catch

This fish is unwillingly caught while fishing for a different species. They are underused and should be eaten more.

GlobalG.A.P.

GlobalG.A.P. certified farms are doing a step in the right direction in terms of sustainability. A few species with this label are getting a better score on the VISwijzer.

Organic

Organic standards are the strictest when it comes to fish feed. They also require certain measures for animal well-being.
