Preliminary tests of an aerated tank system for tilapia culture

A simple tank system, using artificial aeration to supply oxygen and incoming water to dilute metabolic by-products and other wastes, was tested. Blue tilapia, Oreochromis aureus, were grown under a wide range of loads, 7–31 kg liter^?1 min^?1, and densities, 19–77 kg fish m^?3 culture unit. Average yield ranged from 6–10 kg m^?3 culture unit per month. Approximately 14–20 m³ of water was used for each kilogram of fish produced.
