Cod-like fish

Cod-like fishes belong to the Gadidae family. This includes the Atlantic and Pacific cod, pouting, haddock, whiting, European pollock, Alaska pollock and saithe. They live near the seabed in coastal waters and in deeper waters. During the day, they aggregate in schools. At night, they separate to forage independently. Gadidae are omnivorous fish that feed on worms, molluscs, bivalves, crustaceans and small fish. They migrate over large distances to spawn and to hunt on large schools of herring and smelt.

 

 

Saithe

Saithe is a species of fish that belongs to the same family as cod. There are two very similar species: saithe and pollack. Pollack in the UK is called Atlantic or European pollock in the US. Although pollack can reach the same size as saithe, the maximum life span of pollack is shorter by about 8 years old. Saithe can grow up to 130 cm and get 25 to 30 years old and is native to the western and eastern Atlantic Ocean.

Explanation assessment

In 2008 the first fishery on saithe became 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.
. Currently most of the European fishery on saithe is MSC-certified: 97% of the catches from the North Sea and the Skagerrak. Saithe from Iceland is also MSC-certified. There are several methods being used: bottom otter trawl, pair trawl, (increasingly) semi-pelagic trawl, purse seine, Danish seine, gillnet, longlines and handlines.

Explanation assessment

Saithe is vulnerable to 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.

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.

Fisheries 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.

Also known as line fishing. A fishing method in which lines and hooks are used.

is supposed to be low. In addition, the impact of this fishing method on the seabed and the organisms that live near or on the seabed is lower than that of fisheries in other areas.

This fishery is managed by catch-limits. The management plan for Saithe is largely effective, mainly due to extra measures taken by Naturland for this fishery-project.

Final assessment
Explanation assessment

Detailed fishery data are available, a quantitative assessment of stocks is carried out annually. This is a mixed fishery that also catches other species such as cod and haddock. The number of caught juveniles appears to be low. Midwater pair trawls are not destructive to the seabed. A management system is in place and is deemed partly effective.  The main tool to manage the harvest of fish on the Faroe islands is by effort control (number of days).

 

Most of the Faroese saithe fishery is MSC certified, this assessment is about the part that is not certified.

Final assessment
Explanation assessment

Saithe is vulnerable to fishing pressure because this species becomes sexually mature at a relatively high age. This Saith stock is just within safe biological levels, but the current fishing pressure is still too high in these areas.

Fisheries that use demersal otter trawls have a lot of impact on protected and threatened species, like sharks and rays, as they can be caught as bycatch and can become entangled in the nets. Trawl fisheries also cause a lot of harm to the seabed and organisms that live on or near the seabed. In time, this can lead to changes in species composition in these areas.

This fishery is managed by catch-limits. The management plan for Saithe is partially effective in these areas.

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.

Welfare

There is fish available of this species that is farmed or caught using high welfare standards.

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.
