Increasing The Stocking Density of Grouper Nurseries for Aquabusiness Efficiency in Recirculating Aquaculture System (RAS) with Bioremediation

Water quality improvement was carried out by means of recirculation and bioremediation systems in grouper nurseries with high stocking density, thereby increasing production performance. The goal this study to evaluate the effectiveness aquabusiness analyzing rise nursery density using RAS systems. test parameters consist performance, blood glucose levels, physic-chemistry-biology water quality, business efficiency based on productivity analysis. Treatment 1,000 fish/m3 increased survival, total bacteria, Vibrio spp., ammonia, nitrite, all parameters. But it lowers growth parameters, pH, dissolved oxygen values. system at up boosted profit 2.64 times. 14.97% more efficient than 500 which could not be matched
