Blue economy & aquaculture in Ghana.

Blue economy & aquaculture

Ghana's marine fisheries are central to coastal livelihoods. Capture fisheries dominate domestic fish production, with artisanal fishing accounting for the majority of marine output. Industrial distant-water fleets, predominantly foreign-flagged, access Ghana's EEZ under licence and IUU fishing depresses stock sustainability. The blue food system supports several hundred thousand jobs and contributes a meaningful share of GDP.

Aquaculture is expanding. Tilapia and catfish dominate cultured species, with cage culture concentrated in southern coastal zones and inland freshwater bodies. The sector has been hampered by high feed costs and significant post-harvest losses. The Ministry of Fisheries and Aquaculture Development is signalling investment into a Blue Food Innovation Hub aligned with the wider 24-hour economy agenda.

Ghana operates two major ports — Tema (container-focused) and Takoradi (breakbulk). Offshore wind potential is limited in the Gulf of Guinea due to low and seasonal wind resources. Maritime spatial planning is underdeveloped; fishing grounds and offshore infrastructure compete without formal zoning.

For a Norwegian principal, the blue-economy opportunity in Ghana is indirect. The Ministry of Fisheries is pursuing IUU detection and fisheries-surveillance technology. The primary play remains oil and gas.
