Lake Turkana, the largest desert lake in the world, presents a unique opportunity for advancing aquaculture through cage fish culture. A feasibility study conducted by Kenya Fisheries Service, Kenya Marine and Fisheries Research Institute (KMFRI), and Turkana County Government identified Kalimapus Beach as a suitable pilot site. Environmental parameters, including physicochemical water quality, exposure to wave action, and substrate conditions, were analyzed across multiple Beach Management Units (BMUs). Findings indicate the lake has potential for large-scale tilapia farming, contributing to food security, employment creation, and reduced pressure on capture fisheries. Additionally, this study explores the possibility of cage culture for ornamental fish, leveraging Lake Turkana’s biodiversity and natural water clarity. The introduction of high-value ornamental species could expand the economic base, promote sustainable aquaculture, and attract investment in niche markets. Establishing land-based hatcheries at Impressa Beach would support stable fingerling production, ensuring continuous supply for commercial ventures. Recommendations include piloting cage structure designs tailored to local conditions, addressing market dynamics, and engaging stakeholders for socio-economic integration. Successful implementation could position Lake Turkana as a hub for both food and ornamental fish aquaculture, fostering the blue economy’s growth in Kenya.
