Scorpaenidae (also known as scorpionfish) is a family of marine fish that includes many of the most venomous species. It is in the name, scorpionfish have a type of spike or sting that contains a type of venomous slimy substance. Physical characteristics of this type of fish are the compact body, many spikes on head and back and a relatively large mouth. They are widespread in tropical and temperate waters. Most subspecies live at the bottom of the sea and feed with shellfish and little fish. Scorpionfish make use of suction, generated by the oral cavity, to catch their prey.

The most well-known species in the Northesa are gurnards and redfish. The lionfish is also a scorpionfish.


Grey Gurnard (Bycatch)

Grey gurnard is the most commonly found species of sea robin in the North Sea but has little commercial worth. The gurnard has large winglike fins and separate fin rays that are used to walk over the seafloor. In the summer, large numbers of grey gurnard are found in the shallow waters of the southern North Sea. This species is then mostly caught as bycatch in the plaice and sole fisheries. The grey gurnard can reach lengths of 30-60 cm and weigh up to 0.95 kilograms.

Explanation assessment

Grey gurnard 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 [bottom trawl] fishery. There is much bycatch in this fishing method, mainly 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. With bottom trawl fishing there is direct disturbance of the seabed and bottom life.

Although the gurnard fishery is becoming more popular, the catch of gurnard is not regulated. Reliable catch data of gurnard lack and therefore the stock size is unknown. Still, gurnard is probably not overfishedOverfished:
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. 
: there is little focused fishery on gurnard and catches are limited. This species is indirectly controlled by the catch restrictions in the fisheries that have gurnard as bycatch, like the flatfish fishery.


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.


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


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


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