Abstract: Nigeria is Africa’s largest fish consumer by volume and a leading producer. Fisheries and aquaculture contribute between 3 and 4 percent of national GDP, provide around 40 percent of the animal-source protein consumed by Nigerians, and support the livelihoods of around 12 million artisanal fishers and fish farmers. Women constitute over 60 percent of the sector workforce. However, the sector is locked in a structural supply-demand crisis. Domestic fish production meets only about one-third of annual demand of between 3.2 million and 3.6 million mt. The domestic supply deficit of approximately 2.4 million mt is filled by imports that cost Nigeria over USD 1.0 billion annually. Domestic fish production has begun to respond to the growing demand for fish in Nigeria. The Federal Department of Fisheries and Aquaculture reports output rising to 1.4 million mt in 2025 from 1.1 million mt in 2024. This increase in production was attributed to improved federal-state coordination, the use of better aquaculture technology, and establishing more sustainable marine farming systems with the support of Nigeria’s development partners. Nonetheless, the structural deficit in fish supply for Nigerian markets remains large. The constraints hindering growth in Nigeria’s fisheries and aquaculture sector include: A fish-feed cost crisis—feed makes up 60 to 70 percent of aquaculture production costs, The near-absence of cold chains for storing, transporting, and marketing fish, resulting in postharvest losses of up to 40 percent, Illegal, unreported, and unregulated (IUU) fishing costs of USD 450 million per year, Fragmented fish fingerling supply systems, Financial exclusion of artisanal fishers, and An outdated governance framework centered on the Sea Fisheries Act of 1992. Moreover, climate change will acutely affect Nigeria’s fisheries and aquaculture sector. Under high-emission climate-change scenarios, its maximum marine catch potential will fall between 23 and 53 percent by 2050. This makes the scaling up of aquaculture not merely an economic growth option but a structural and nutritional necessity. However, aquaculture will also be adversely affected by a changing climate, with growth in aquaculture in Nigeria expected to decelerate from 11 percent per year between 2010 and 2015 to only 2 percent per year in the 2035 to 2050 period. The National Fisheries and Aquaculture Policy, 2025–2029, provides the operational framework for the growth of the fisheries and aquaculture sector. Its principal target is to achieve aquaculture output of 1.3 million mt by 2029 while cutting postharvest losses in half. This paper concludes that any strategic action plan for Nigeria’s fisheries and aquaculture sector must be built around closing the supply deficit through accelerated sectoral growth that is anchored in improved domestic feed and fingerling supply systems, cold chain investment at 12 priority fish landing sites, reforms of the Sea Fisheries Act to address IUU fishing losses, and a dedicated fisheries investment facility to correct the structural financial exclusion of Nigeria’s fisheries and aquaculture sector.
