Sea urchin

The sea urchin is a spiny invertebrate with a radial symmetry, different from our own bilateral symmetry. Although a sea urchin may appear to have an exoskeleton, the skeleton is actually internal with a firm skin over it. Sea urchins are herbivorous and scrape the rocks for algae. In the kelp forests of the US west coast, they cause problems as a result. Due to overfishing of predators, the sea urchin population there has grown massively, threatening to eat the kelp forests. Still, one sea urchin is not the other. Sea urchins are important links in the ecosystem and can also be overfished, as has been the case in Europe due to the high demand from France.

Final assessment
Explanation assessment

There are only very little information available on the stocks of stony sea urchin (P lividus) in ICES IX (West of Portugal) There are no stock assessments available for this species, fishing data are only available as total catches. This is an invertebrate species to which the classical risk factors are not applicable, Thus the stock status, and the species vulnerability and resilience are unknown. The species is managed Spanish (Galicien) and Portuguese waters by an extensive set of catch and effort limitations. The current fishing practice is considered not the threaten the stock.

Hand picking by divers is among the most conservative fishing methods in use; As the species are individually picked up on sight, there are no discards and no bycatches (either non-target or ETP species) at all. Habitat damage is negligible. Ecosystem effects caused by this fishery are highly unlikely.

The management framework established by the EU is considered partly effective, however this small scale fishery is difficult to manage through conventional methods.

Final assessment
Explanation assessment

There are only very little information available on the stocks of purple sea urchin Sphaerechinus granularis in Brittany (ICES VIIe). Despite the increasing importance of S. granularis as a fishery resource in some parts of the species distribution range, its biology is scarcely studied. The existing information is limited to the reproductive biology and the life strategy of the species in relation to food availability. There are neither stock assessments nor explicit landings data available for S. granularis.

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.
