In the past few decades, Recirculatory Aquaculture Systems (RAS) were introduced to waste water treatments, by focusing on water reuse after treatment. In this study, the technical viability of the Recirculatory Aquaculture Systems (RAS) was analyzed for introduction in organic aquaculture systems. The high water exchange, insufficiency of organic- rich water in the organic aqua farming system, as well as water reused in aquaculture in modern concept becomes a necessary installed trickling filter in organic fish farming. Three biological plastic filter media i.Nylon pot scrubber (NPC) ii.cylindrical plastic media (CPM) and iii. rubber bands (RB) have been evaluated in biological treatment for organic pond water in 60 days batch culture then continuous culture. Water quality parameters tested were parameter like TAN, nitrate, nitrite, BOD, COD etc. In Nylon pot scrubber (NPC) media were better performance than other two media. At the end of the experiment, notable differences were observed in the ammonia removal rates in different filter media. The Nylon Pot Scrubber media led to the maximum mean N-TAN removal rates (0.24 g N-TAN removed m−2 day−1). At the end of the experimental period, the nitrification rate (%) was 99% in the Nylon pot scrubber (NPC), columns, 97% in the cylindrical plastic media (CPM) columns, 94% of the rubber bands (RB). Recirculatory water treatment systems are extremely suitable for organic aquaculture system. The results show the organically grown fish pond water to be highly feasible for Trickling filter for Recirculatory Aquaculture Systems (RAS) the operational Standpoints.
