Common cockle

The common cockle is a bivalve that can be found in the north-eastern Atlantic Ocean. In the Netherlands, this species can be found in the Eastern Scheldt and the Wadden Sea. The common cockle lives buried in the seabed with only its two siphons protruding above the sand. One siphon is used to suck in water and nutrients. The other siphon is used to excrete water and excess nutrientsThe ideal habitat for the common cockle is the intertidal zonethe zone which falls dry at low tide

Fishing with (mechanised) dredgesBoat dredges:
A fishing method used for collecting shellfish and crustaceans from the bottom. The ship drags a steel frame with a net over the bottom, in which shellfish and crustaceans are caught. Large ships can drag multiple dredges simultaneously, on each side of the ship.  
, including the hydraulic dredges, can lead to a long-term change in species composition in the ecosystem. This fishing method often has high 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).

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

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.
