Nigeria is the largest fish producer in Sub-Sahara Africa. Fish plays crucial role to support fish producers and post-farm gate value chain actors’ livelihood. Despite the virtues of aquaculture and fisheries sub-sectors to enhance value chain actors livelihood, major gaps exist related to fish value chain efficiencies, including financial performance of post-farmgate actors, gender-disaggregated data on value chain actors, the roles of women and youth in fish trade, and post-farmgate food safety practices. The aim of this study is to fill post-farm gate fish value chain data gap to provide evidence-based policy suggestion to enhance the aquaculture sub-sector in Nigeria.
