Abstract: This comprehensive technical report evaluates the socioecological and economic dimensions of cage aquaculture in Kenya's Lake Victoria region, spanning Busia, Siaya, Homa Bay, Kisumu, and Migori counties. It documents rapid growth of cage installations?over 5,000 units?and assesses infrastructure quality, fish health, feed access, water parameters, community ownership, and sustainability risks. Field surveys and GPS mapping provide insight into production patterns and environmental stressors such as algal blooms, poor seed quality, and lake ecosystem deterioration. Institutional challenges include fragmented policy coordination and gaps in aquaculture regulation. The report recommends nature-based solutions including lake zoning, nutrient recycling, capacity-building for farmer groups, and targeted extension services. Its focus on community models highlights participatory governance, improved market integration, and climate resilience in aquatic food systems. The study is instrumental for informing investment, conservation planning, and policy formulation in Kenya?s blue economy.
