Coastal West Africa, including Seychelles, is a region with significant aquaculture potential but faces challenges in achieving sustainable food security through this sector. A comprehensive search strategy was employed using electronic databases such as OVID Medline and Web of Science. Studies published between and were included, focusing on aquaculture practices and their effects on food security indicators. Data analysis involved thematic synthesis across studies. The review identified a trend towards increased fish farming productivity in Seychelles, with an average annual growth rate of 4% over the last decade. Aquaculture has become a critical component in addressing food security challenges, particularly for small-scale farmers who rely on aquatic resources as a supplementary income source. Policy makers should support extension services to improve aquaculture practices and market access for local producers. Enhanced education programmes targeting climate resilience are also recommended. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
