Abstract

It is necessary to maintain optimal water quality parameters for a proper operation of a recirculating aquaculture system for fish breeding. A biological filtration installation has to be performed so that to satisfy the system requirements on the conversion of ammonia to nitrite and then to nitrate, less toxic products for the fish population. The presence of ammonia and metabolites in water is a stress factor for concentrations higher than 0.05 mg/nitrogen ammonia (NH3 - N) and this will be felt in the growth of fish and in their resistance to disease.
