The Clownfish (Amphiprion spp.) Larviculture Technique with Recirculating Aquaculture System (RAS) in Buleleng, Bali

Clownfish is one of the most demanding-marine ornamental fish. Due to increased demand clownfish, wild clownfish catch has also been increasing, until reaching overexploitation condition. One way preserve existence this fish species and sustainably fulfil market by conducting a culture technique with advanced application using recirculating-aquaculture system, specifically larviculture. Thereby, paper reported procedure larviculture determined growth performance larvae during activity. This reviewed direct observational operation for 40 days at Rizky Mitra Karya Hatchery, Buleleng, Bali. All data were analyzed descriptively. During culture, process was composed rearing media preparation, egg-clutch collecting stocking, larval rearing. included feeding management in each part (broodstock rearing), water quality control setting RAS standard harvest juvenile However, hatching rate lower than given. Egg collection scrapping method produced due more human error discovered. To gain better improvement, rotifer as live feed fluctuated weather condition seasonal transition, which impacted on availability should be handled intensively. Therefore, proper indoor thorough intake observation larvae, stocking directly taking from broodstock tank are necessary stabilize production high sustainability level.
