Sustainable fish farming is becoming a reliable way to improve food security and create local jobs.
These entrepreneurs are using better farming methods, smarter tools, and community-focused solutions to produce healthy fish while protecting the environment.
Here are the top 5 African entrepreneurs leading sustainable aquaculture, based on verified impact, innovation, leadership, and active work as of 2025:
— Bridget Njenga (Kenya): Co-founder & CEO of Acquaden. Njenga supports small-scale fish farmers with quality fingerlings, training, and feed access. She promotes circular aquaculture, including alternative feeds like azolla and seaweed, and encourages farmers to reuse nutrient-rich pond water for crop irrigation.
— Dave Okech (Kenya): Founder & CEO of AquaRech. Okech created a digital platform that connects fish farmers with buyers, trainers, and input suppliers. The platform reduces operational costs, improves access to quality feed, and strengthens the aquaculture value chain.
— Pete Ondeng (Kenya): Founder of Ohala Kenya. Ondeng leads sustainable blue-economy projects around Lake Victoria. Through the Lake Victoria Aquaculture Association, he supports environmentally responsible fish-farming systems that generate livelihoods and preserve natural resources.
— Frank Owusu (Ghana): Founder of Aquamet. Owusu developed a smart water-quality monitoring system that provides real-time data on oxygen, temperature, and other critical parameters. His innovation helps fish farmers reduce losses, make data-driven decisions, and improve farm efficiency.
— Jack Oyugi (Kenya): Founder of Aquaprotein. Oyugi processes invasive water hyacinth, harvested from Lake Victoria, into protein-rich, low-cost fish feed. This innovation helps reduce environmental damage while lowering costs for small-scale farmers.
These entrepreneurs show that sustainable fish farming in Africa can balance profitability, community upliftment, and ecological health, creating food systems that are not just productive, but responsible.
