The diagnosis of maritime fisheries in the Republic of Guinea is being carried out with AFD's support to the CSRP, with the aim of strengthening the participation of professional fishing organizations (POs) in the governance of the activity on which their lives depend. It focuses mainly on small-scale maritime fisheries, and attempts to update knowledge of the sector. It also refers to the types of PO present on the Guinean coast. The work is being carried out by ADEPA. It consists of a literature review, supplemented by qualitative interviews. Guinea's natural conditions, with an exceptionally wide continental shelf and extensive mangrove swamps, are conducive to the development of fishery resources. These resources are coveted by both artisanal and industrial fisheries. Pelagic fish account for 2/3 of Guinea's fishing potential. Commercial fish, shrimps and cephalopods are also exploited.
