[IFAD] Despite their vast water resources, Ghana and Nigeria import most of their fish, with demand outstripping supply. Local fish numbers are depleting due to overfishing and a lack of regulation. With many communities dependent on fishing as a source of income and food, less fish can have drastic knock-on effects, including reduced food security.
But there is a solution to meet growing demand. Cage aquaculture involves raising fish inside mesh enclosures in natural water bodies. This way of farming fish is more accessible since there is no need to procure land and farmers can use public waters. Cage aquaculture also has a lower carbon impact as it does not need expensive and energy-intensive water pumps.
