Evaluate CycloBio fluidized-sand biofilter technology. management strategies and technology that producers can select as the most appropriate for their existing aquaculture operation were generated from this research. Waste (i.e., TAN, nitrite, TSS, DOC, and TOC) production rates will be quantified as a function of feed fed within the fully recirculating system. When placed between adjacent water compartments, air delivered inside of the tube drives the water out of the tube and into the adjacent compartments. Assuming all the land uses an intensive cultivation system, more than two million paddlewheels worth more than 10 trillion will be needed by 2024. By eliminating the need for settling tanks or ponds, the leaching of nutrients (phosphorus, nitrogen) is minimized and the dewatered sludge is in a form that fish farmers could readily transport, store, or send for disposal. This feature led to tilapia being referred to as an' aquatic chicken' (Maclean, 1984).
