Description:

Small demersal fish

Example species: Grey gurnard

Habitat: Demersal
Main role: Predator
Trophic level: 4,5

Diet: Juveniles feed on a variety of crustaceans. The diet of older specimens consists mainly of juvenile fish.

Threats: Grey gurnards are of lesser commercial importance, and are mostly caught as bycatch for other flatfish.


Large demersal fish

Example species: Thornback ray

Habitat: Demersal
Main role: Predator
Trophic level: 3,8

Diet: This ray feeds on fish and invertebrates.

Threats: Of commercial interest and near threatened according to IUCN red list. The thornback ray is often caught as bycatch by trawl and gillnets.

MSP Challenge 2050:

The small demersal fish group includes the following species: eelpout, shorthorn sculpin, Vahls’s eelpout, longspined bullhead, hooknose, common seasnail, greater weever, lesser weaver, snake blenny, striped red mullet, solenette, thickback sole, mediterranean scaldfish, argentine, dragonet, piper gurnard, red gurnard and grey gurnard.

In different languages

Grey gurnard

  • SN: eutrigla gurnardus
  • EN: grey gurnard
  • NL: grauwe poon
  • GE: Graue Knurrhahn
  • DK: grå knurhane
  • FR: grondin gris
  • NO: knurr
  • SE: knorrhane

The grey gurnard is an abundant demersal species. Gurnards are key predators in the North Sea and have become more important in recent years. In winter they form dense aggregations locally to the northwest of the Dogger Bank, whereas in summer they are more widespread. This fish produces sounds.

Thornback ray

  • SN: raja clavata
  • EN: thornback ray
  • NL: stekelrog
  • GE: Nagelrochen
  • DK: sømrokke
  • FR: raie bouclée
  • NO: piggskate
  • SE: knaggrocka

The thornback ray is usually found on shallow mud, sand, or gravel seabeds up to 60m depth. It is less abundant in the southern North Sea. Its population levels are presently too low for the ray to fulfill its ecological role.
