This study aimed to determine the use of water exchange with flow through system for growing abalone, Haliotis squamata. This study was conducted using a completely randomized design with three replications. Briefly, abalone with average body weight 4.90±0.17 g, shell length 31.31±0.17 mm, and shell width 19.10±0.75 mm were subjected to varying rate water exchange and then control. This research water exchange of flow through system were set up at 0% (FT 0), 50% (FT 50), 100% (FT 100), 200% (FT 200) and 400% (FT 400). The results show that all water exchange had significantly different to the control (FT0). Growth response of FT 400, FT 200, FT 100, FT 50, and kontrol were 0.84±0,07%; 0.73±0.06%; 0,74±0,06%; 0.67±0.02%; and 0.46±0.02%, respectively. More over, FT 400 gain it’s shell growth highest (0,28±0.04%) than others. The growth of abalone shell length at FT 400 (105,72±0,53 μm) system treatment provide good growth than to control (59,67 0.41 μm). Water exchange with flow through system can support growth rate of abalone. FT 400% give survival rate, increase production, quality abalone and effieciency of the best diet.
