Sažetak
Recirculation aquaculture system (RAS) is the type of land based aquaculture production that interferes the least with the environment, particularly by low effluent volume and overall water requirement. Water reuse, sometimes limited by accumulation of waste products excreted by fish, can be improved by incorporating another biotechnical segment in the form of high rate algal pond (RAS+HRAP) adding to the economy and self sustainability of the system. Our goal was to evaluate if 1-year rearing conditions in the RAS and RAS+HRAP, differ in fish production and health by assessing: 1. fish growth ; 2. impact on the morphological structure of sea bass target tissues (liver, kidney, spleen) ; 3. susceptibility to monogenean parasites ; 4. resistance to pathogenicity challenge with Listonella anguillarum ; and 5. total blood protein. In one- year period, sea bass showed no statistical difference in any of evaluated parameters suggesting satisfactory purification rate in RAS+HRAP system.
