Aquaculture or fish farming means the artificial breeding and raising of aquatic creatures. They include fish as well as crustaceans and shellfish, which are raised and stocked under controlled conditions by using techniques and technologies offering an increased level of productivity which cannot be realized under natural conditions. Due to the increased demand for freshly caught fish and considering the imminent overfishing of the oceans, aquacultures attach growing importance while there are different types of aquaculture installations.
For instance, aquaculture can be found in stagnant or streaming waters under open air (outdoor fish farming), in net compounds in the sea (sea farming) or in indoor fish farms. All systems with “closed” water cycles have one thing in common: they make high requirements to the applied water treatment technologies – for this reason, the German company Multi Umwelttechnologie AG developed the “Mutag BioChip™ RAS Process”.
