Performance of Production Abalon (Haliotis squamata) Quality using water Exchange by Flow Through System

Abstract

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.
