Flatfish

Flatfish belong to the order Pleuronectoformes. There are more than 500 species of flatfish. Flatfish live on and partly in the seabed, only the halibut swims higher up in the water column. Flatfish have an oblong, flat shape and their eyes on one side. The upper-side, the eye-side, of the flatfish has a camouflage colour and the underside is white. It may seem like flatfish swim on their belly, however, in fact, they are laying on their side. Flatfish larvae have a regular fish shape, with eyes on each side and a vertical swimming mode. After 6 weeks, one of the eyes migrates upwards, over the head to the other side. From now own, the flatfish swims with their eyes up and their blind side facing the seabed.

The best known flatfish species in the Netherlands are sole and plaice. Other flatfish species that occur in the North Sea are the common dab, halibut, turbot, brill, European flounder and lemon sole. Flatfish are caught with beam trawls, pulse trawls or demersal otter trawls.

Yellowfin Sole

A lot of flatfish, which is caught in the Pacific Ocean, can be found on the Dutch market, especially yellowfin sole and rock sole. These flatfish can reach up to 60 cm in length and have a lifespan of 22 years. Yellowfin sole can be found in the northern part of the Pacific Ocean at depths of up to 550 metres.

BottomBottom trawls:
A fishing technique in which cone-shaped nets terminating in a codend are dragged through the water column or along the bottom. trawls are likely to cause significant negative impacts on the ecosystem by interacting with benthic habitats and species. 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). of other species, including endangered and protectedProtected species:
Many marine species are protected from deliberate or intentional disturbance, capture, injury and killing, and in some cases possession or sale. Species are often protected if they play an important role in the ecosystem or are sensitive to fishing. These marine species are protected regardless of whether they are inside or outside marine protected areas. species, is likely and often documented.
