This study examined the activities, challenges, and sustainability strategies of artisanal fish farmers along the River Niger using 2025 survey data. Descriptive statistics were used to analyse respondents’ perceptions. Findings indicate that artisanal fish farming remains a key livelihood, with 83% of respondents affirming its importance. The sector is still largely traditional (81%), though 74% reported a gradual shift toward modern aquaculture practices. About 72% depend on natural water bodies, while 68% engage in fish processing and preservation. Production trends appear positive, as 90% observed increased fish output over the past five years. Most respondents also reported adequate resources (82%), year-round availability (87%), and general abundance of fish in the river system (87%). However, several constraints persist, including inadequate technical knowledge (83%), limited access to equipment (91%), climate change impacts (84%), flooding (88%), and weak government support (82%). Farmers respond through collaboration (87%), use of indigenous knowledge (85%), and income diversification (82%), though access to credit remains limited (74%). Overall, the study suggests that while artisanal fish farming supports livelihoods and food security, its sustainability depends on addressing key technical, environmental, and institutional challenges.
