The Guinean tonguesole (*Cynoglossus senegalensis*) is a demersal flatfish native to the eastern Atlantic coast of West Africa, particularly abundant from Mauritania to Angola. This species thrives on sandy and muddy bottoms in shallow coastal waters and estuaries, making it a valuable resource for local fisheries. The primary countries engaged in harvesting Guinean tonguesole are Senegal, Guinea, Sierra Leone, and Ghana, where the fish is caught mainly by artisanal and small-scale commercial fleets using trawls and gillnets. The tonguesole is prized for its mild flavor and is a staple in local diets, with much of the catch consumed domestically, though some is exported regionally. The fishery supports thousands of livelihoods but faces challenges such as overfishing, habitat degradation, and the need for improved management to ensure sustainability.
