The effects of feeding rate (0.5%, 7.5%, and 10% body weight [BW] per day [BW day−1]) on the growth, survival rate, and feed conversion ratio of rabbit fish, Siganus guttatus, (initial BW of 2.0 ± 0.5 g, density of 16 individuals 80 L−1) were investigated in a water recirculating aquaculture system of Integrated Multi Trophic Aquaculture (IMTA model involving mussel Perna viridis, sea urchin Diadema sitosum, and seaweed Kappaphycus alvarezii. Triplicate groups of fish were fed an comercial diet (55.4% protein, 14.1% lipid) four meals a day (8 a.m, 12 a.m, 4 p.m, dan 8 p.m) for 12 weeks. Survival rate (SR), body weight gain (BWG, specific growth rate (SGR), and feed conversion ratio (FCR) significantly affected (p<0.05) by feeding rate. Experimental application of the IMTA model shows that although the amount of feed given is higher, it can produce better growth performance.
