Fish Farming – Bio-security for Fish Rearing: Re-circulating Aquaculture Systems
Re-circulating Aquaculture is a technique for raising water borne animals in a closed (usually indoor) system which minimizes water consumption, provides maximum control of the livestock’s environment, and reduces the risk of exposure to parasites, disease, and predators High Density Re-circulating Aquaculture System (HDRAS) is a system in which aquatic organisms are cultured in water which is serially reconditioned and reused. Closed-system aquaculture presents a new and expanding commercial opportunity. Re-circulating aquaculture systems (RAS) are tank-based systems in which fish can be grown at high density under controlled environmental conditions. They are closed-loop facilities that retain and treat the water within the system. >click to read<09:33
