Abstract
Obzirom na sve veću potražnju za slatkovodnim i morskim proizvodima na tržištu, akvakultura se smatra ostvarivim rješenjem njihove globalne opskrbe. Održiva uporaba i upravljanje vodom koja se koristi u akvakulturi vodenih organizama, dugotrajno je ekonomsko i ekološko pitanje. Recirkulacijski sustavi u akvakulturi (RAS) su ključna tehnologija koja će zajednici svjetske akvakulture, na ekološki prihvatljiv način, omogućiti opskrbu svjetskih potreba za akvakulturnim vrstama tijekom narednih desetljeća. Glavni problem navedenih sustava je održavanje konstantne i optimalne kakvoće vode. Uklanjanjem otpada iz RAS-a se upravlja mehaničkim filtriranjem vode, čime se uklanjaju krute tvari, te biofiltracijom tj. pretvorbom toksičnih metabolita dušika u manje toksične oblike. Biofiltracija se postiže u nitrificirajućem bioreaktoru uz pomoć specifičnog konzorcija nitrificirajućih bakterija. Proces uklanjanja amonijaka bakterijskim putem naziva se nitrifikacija, a sastoji se od uzastopne oksidacije amonijaka do nitrita te konačno do nitrata. Općenito, procesom nitrifikacije razlažu se otpadni proizvodi dušičnog podrijetla koje izlučuju organizmi u akvakulturi. Bolje razumijevanje procesa nitrifikacije može pomoći pri operativnim modifikacijama sustava a time i postizanju odgovarajućeg učinka RAS-a.
Abstract (english)
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.
