Aquaculture is the future of sustainable food production. It is the world's fastest growing food sector, with an estimated worth of 200 billion USD, but every year, farmers face a crisis with managing disease, losing more than 10 billion USD worth of fish stocks annually. MicroSynbiotiX is developing cost-effective oral vaccines to combat these infections and improve global food security. We are developing a novel, patent-pending method of producing oral vaccines using transgenic microalgae. Our solution will make disease management much more sustainable and reduce the need for antibiotics.
