The continental shelves of Guinea-Bissau, Guinea and Sierra Leone are characterized by coastal fish assemblages of croakers principally located in the nutrient-rich estuarine and inshore areas.
Exploitation
 

Marine resources of the Gulf of Guinea are mainly exploited by Côte d'Ivoire, Ghana, Togo, Benin, Nigeria, Cameroon and Equatorial Guinea, among others. Multi-species fisheries are common in the Gulf of Guinea. Small pelagic resources are exploited mainly by artisanal and semi-industrial purse-seine in Côte d'Ivoire, Ghana, Togo and Benin and exclusively by small-scale fisheries in Nigeria and Cameroon. Coastal demersal resources are composed of sciaenids (exploited by small-scale and semiindustrial fisheries in Nigeria, Benin, Togo and Cameroon), groupers and snappers (fished in Togo and Ghana with hook-and-lines in untrawlable areas), and sparids (Côte d'Ivoire and Ghana). The white shrimp resources off Nigeria and Cameroon are fished exclusively by artisanal fisheries while pink shrimp is exploited by trawlers of the semi-industrial fishery. Penaeid shrimps in Togo and Benin and in Côte d'Ivoire are caught in lagoon fisheries. The offshore demersal resources of Ghana and Côte d'Ivoire are made up of sparids along with the slope community, while the offshore demersal resources of Nigeria and Cameroon are primarily drift fish (Arioma spp.) and redfishes (Scorpaenidae).
Biological State and Trend
 
Cuttlefish stocks

The exploitation rate applied to cuttlefish stocks in Guinea has been increasing since the 1990s and by 2001 with a catch of 5800t the stocks were considered to be overexploited (FAO, 2003c).
Southern pink shrimp in Guinea and Sierra Leone

Current annual production of southern pink shrimp in Guinea and Sierra Leone is around 2 000t. The species is considered moderatly exploited in Sierra Leone whereas in Guinea the species is considered overexploited (FAO, 2003c).
Demersal species in the Gulf of Guinea

Trawl surveys carried out on the Western Gulf of Guinea continental shelf by the RV Dr. Fridtjof Nansen have shown that between 1999 and 2001 the estimated biomass of demersal resources varied somewhat in the period from 17 500t to 39 500t. In the Gulf of Guinea, from Ivory Coast to Cameroon the potential of shrimps were estimated at 10 000t, and stocks were considered highly exploited (FAO, 1999). Demersal resources were found to be either fully or overexploited (FAO, 2004a, b). Due to inconsistencies in the input data, the CECAF Demersal Working Group recommended that a precautionary approach, avoiding any increase in fishing effort, should be adopted for all the demersal species in the Gulf of Guinea (FAO, 2003c, 2004 a, b).
Small pelagic species, west and central Gulf of Guinea

Small pelagic species (sardinellas, mackerels and anchovies) are important but unstable resources in the Western Gulf of Guinea shared by Côte d'Ivoire, Ghana, Togo, and Benin which further complicates the management of the fisheries exploiting them. Potentials of small pelagic in the west and central Gulf of Guinea have been estimated at 330 000t and seem to be fully exploited. Many countries have not developed appropriate database and research structures to evaluate the state of the stocks and their explotation.
