Strict environmental restrictions force the aquaculture industry to guarantee optimal water quality for fish production in a sustainable manner. The implementation of anammox (anaerobic ammonium oxidation) in biofilters would result in the conversion of both ammonium and nitrite (both toxic to aquatic animals) into harmless dinitrogen gas. Both marine and freshwater aquaculture systems contain ...

The recirculating aquaculture system (RAS) is a land-based facility, either open-air or indoors, that minimizes water consumption by filtering, adapting, and reusing water. Solid organic matter from fish waste food directly becomes needs to be eliminated because it source of increasing total ammonia nitrogen (TAN), suspended solids (TSS), dissolved (TDS), also has an impact on reducing oxygen (...

The aim of this study was to examine the effects ozonation on water quality, and growth, blood biochemistry, antioxidant capacity survival pikeperch (Sander lucioperca) reared in a recirculation aquaculture system for 30 weeks. A group without ozone treatment used as control. application led significant reduction chemical oxygen demand, biological demand unsuspended solids concentration. result...

The presence of a human community on the Moon or Mars for long-term residence would require setting up production unit allowing partial total food autonomy. One major objectives bioregenerative life-support system is to provide sources crewed missions using in situ resources and converting these into necessary sustain life space. nutritive quality aquatic organisms makes them prospective candid...
