™AquaEco Hatcheries formerly (Aqua-Farms Hatcheries) is a youth-led science-based tilapia hatchery that produces a variety of tilapia fingerling strains; Our hatchery can produce 1.5 million fingerlings a year. We utilise advanced technology that decreases the demand of tilapia seeds by7%, cutting down the deficiency of tilapia fingerlings to 76% equivalent to 1,200 more fish farmers supplied with quality fish seeds in each year. We have global advisory insights from Europe, North America, and other international institutions assisting our expansion.
