The RAS, a land based RAS, allows fish growers complete year round control over all growing conditions. The advantage of a well designed and well executed Indoor Recirculating Aquaculture System cannot be underestimated. In areas where the amount of available water is low or for projects where the cost of warm water is high, this model excels.

Whether your project will use fresh water or a marine system, an Indoor RAS works on the same principles. One strength of the system is its ability to allow water quality of the rearing environment to be controlled while minimizing the entry of pathogens. The discharged water carrying waste and other debris goes through a series of treatments before being partially or totally reused. The designers at Zhonghang balance cost effectiveness and energy efficiency against environmental impact and the needs of the fish for optimal growth.
