Summary:To increase sustainable aquaculture production, recirculating aquaculture systems (RAS) are among the most widely used aquaculture production systems. This research aims to determine the performance of small-scale RAS with different biofilter media. The current research was carried out in 4 sets of RAS, with different treatments. The treatment is differentiated based on the biomedia used, namely: pumice, moving bed bioreactor (MBBR), bioball, and no media as control treatment. Nile Tilapia (Orechromis niloticus) are used as testing organisms. Fish performance will be measured by analyzing the specific growth rate (SGR), the food conversion ratio (FCR), and the survival rate. The water quality data was descriptively analyzed to see trends in the recirculating system. The results showed that the MBBR treatment provided the best values for the parameters reflecting the performance of fish growth (SGR 3.24±0.26% and FCR 1.30±0.18), the water quality, and the degree of ammonia purification (4.16%), which were significantly better than in the control treatments. It is recommended to use MBBR in the biofilter for the best performance in small-scale RAS for fish farming. This research will be the first step in developing small-scale RAS designs, especially for aquaculture activity in developing countries.
