Flatfish

Flatfish often lie partly hidden in the sand. The upper side has good camouflage colouring, while the underside is white. They have a flattened body and eyes on the upper side. A flatfish larva does not have a flattened shape, but the “normal” shape of a fish. After about six weeks, one eye moves to the other side, close to the other eye. From then on, the flatfish swims with its blind side underneath and both eyes on top. The best-known flatfish species in the Netherlands are plaice and sole. Dab, turbot, brill, flounder and megrim are also common in the North Sea.

Senegalese sole

The Senegalese sole is a marine flatfish that inhabits sandy and muddy bottoms in the eastern Atlantic Ocean, from the Bay of Biscay till Senegal. It can reach up to 60 cm. Solea senegalensis is very similar to the common sole. It has a flattened, oval body with the dorsal fin starting on the upper profile of the head to the front of the upper eye. It is greyish brown in colour on the eyed side marked with numerous blue spots, the spots tend to disappear in dead specimens. The pectoral fin on the eyed side has a nearly black membrane contrasting with cream coloured fin rays while the caudal fin is plain. The blind side it whitish. Its diet consists of shellfish, shrimp, crabs and fish.

Final assessment

Explanation assessment

As yet, it is not clear how the Senegal sole stockStock:
The fish of a particular species reproducing in the same area in the same period. is doing. This species is fairly sensitive to fishing pressureFishing pressure:
Fishing pressure is a result of the fishing effort/amount of fishing on a stock, which determines the fishing mortality. Fishing mortality is the share of the fish stock that dies annually as a result of fishing..

Demersal fisheries with anchoredanchored/demersal gillnets:
A fishing technique whereby passing fish become tangled up in a net with their gills (also known as a gillnet), which is vertically standing on the bottom. gillnets and trawlTrawl nets:
A fishing technique whereby conical nets ends up in a pit, by dragging the nets through the water column or over the bottom. nets most likely have a significant impact on the ecosystem. Both fishing methods come in contact with the seafloor and may disturb sensitive benthic habitats. 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.

There are no laws or regulations on fishing in Senegal for this species. There are management measuresManagement measures:
