Sažetak
Aquaculture is the most probable and feasible solution to providing the aquatic products for an ever-increasing market demand. Sustainable use and management of water used for aquaculture of aquatic organisms is long lasting economical and ecological issue. Recirculating aquaculture systems (RAS) are the key technology that will allow the world aquaculture community to supply the world per capita needs for aquatic species over the coming decades and will do so in an environmentally friendly manner. A major problem in these systems is the maintenance of a constant and optimal water quality. Elimination of waste is generally managed through mechanical filtration to remove solids, and biofiltration for the conversion of toxic nitrogen metabolites into less toxic forms. This is accomplished in the nitrifying bioreactor using a specific nitrifying bacterial consortium. Nitrifying bacteria process dissolve nitrogenous waste products excreted by the aquatic organisms being cultured. The process of bacterial driven ammonia removal is called nitrification, and consists of the successive oxidation of ammonia to nitrite and finally to nitrate. A better understanding of nitrification process can help appropriate performance through operational modifications of RAS.
