Fish are cultured in flow-through systems, consisting of earthen ponds, concrete raceways, or tanks. Water quantity and quality determine the carrying capacity and production of flow-through systems. The incoming water supplies oxygen and flushes away metabolic wastes. Other production systems include ponds, cages, and recirculating systems. The present study examined the effects of three recirculation rates (50%, 200% and 400%) on water quality and biomass growth at low and high fish stocking densities (122 and 220 fish/m 3) in aquaponic systems.The system consisted of a Tilapia tank connected to a gravel filter and three hydroponic trenches in series with Ipomoea aquatica, Lactuca sativa and Canna glauca.

The water supply system (water intake, pumps, pipelines) must be designed for the maximum water flow. In most of the fish production systems the flow-through water is not modified during the growing season, it is constantly at a value determined by equation (34). In this case the amount of water utilized during the growing season is: Fish culture in flow-through systems is a type of intensive culture where the fish are stocked densely in a long and narrow pond or tank in which there is an abundant continuous water flow.

On the other hand, some stormwater ponds seem to have chronic problems with fish kills and would benefit from a circulation system. Stormwater ponds are prone to excessive weed and algae growth. If large masses of these plants are killed using aquatic herbicides, the resulting decay will remove oxygen from the water and may cause a fish kill. Aeration can help prevent such a fish kill. Finally Recirculating aquaculture production systems may offer an alternative to pond aquaculture technology. Through water treatment and reuse, recirculating systems use a fraction of the water required by ponds to produce similar yields. Because recirculating systems usually use tanks for aquaculture production, substantially less land is required.
