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===

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.

The large demersal fish group includes the following species: rabbit fish, John Dory, sea trout, Norway red fish, Bluemouth, roundnose grenadier, starry ray, spotted ray , Common skate, cuckoo ray and thornback ray.

Demersal fish is a month-by-month, computer generated data layer following calculations made by the ecosystem simulation (EwE).

Different pressures generate by human activities (noise, bottom disturbance, surface disturbance, artificial substrate) have different, complex effects on marine species in terms of movement, survival and procreation.

Demersal fish are caught by all fishing fleets, but mostly by bottom trawl.
