Description:

Example species: Sole

Habitat: Demersal
Main role: Predator
Trophic level: 4

Diet: The main preys are polychaetes and meiofauna, but large specimens also eat small fish such as gobies and dragonets.

Threats: Highly commercial. Sole is mainly caught in the southern North Sea and off the Danish coast. In the English fishery, the high value of sole makes it one of the most important species targeted by inshore vessels using trawls and fixed nets. Sole is also taken as a target and by-catch species by offshore beam- and otter-trawlers and gillnetters.

MSP Challenge 2050:

The flatfish group includes the following species: witch, long-rough dab, flounder, lemon sole, turbot, brill, megrim, halibut, sole, plaice and dab.

Flatfish 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.

Flatfish are caught by all fishing fleets, but mostly by industrial and pelagic trawl.

Sole

In different languages

SN: solea solea
EN: common sole
NL: tong
GE: Seezunge
DK: søtunge
FR: sole commune
NO: tunge
SE: sjötunga

The common sole is a flatfish living on the sandy or muddy seabed, often burying itself in the substrate. It grows to a maximum length of about 70 cm.

Example species: European plaice

Habitat: Demersal
Main role: Prey
Trophic level: 3,2

Diet: Plaice is predominantly benthivorous, although larger specimens also feed on small demersal fish.

Threats: Highly commercial. The North Sea has the largest fishery for plaice in all of Europe. They are traditionally caught in a directed beam-trawl fishery and in a mixed fishery with sole. Plaice are also a by-catch in inshore and offshore otter-trawl fisheries.

In different languages:

SN: pleuronectes platessa
EN: european plaice
NL: schol
GE: Scholle
DK: rødspætten
FR: plie commune
NO: rødspette
SE: rödspätta

The European plaice is a common flatfish occurring on sand and muddy sea beds, typically at depths between 10 to 50m, but can be found up to 200m. They are resilient to changes in salinity.

Example species: Dab

Habitat: Demersal
Main role: Prey
Trophic level: 4

Diet: Dab is a dominantly benthivorous fish species, although larger specimens occasionally feed on small demersal fish.

Threats: Dab is commercially fished with trawl nets.
