Abstract
This research compares a traditional Biofloc system to a Semi Recirculatory Aquaculture Biofloc system. The latter like the conventional Biofloc system, follows the same culture pattern, with the exception of a recirculatory mechanism integrated into the culture process, which could cause considerable differences. For this study, we chose two farms in Kerala's Ernakulam district: Kodungaloor and Aroor, which use Semi-RAS and normal Biofloc systems, respectively. Water quality indicators, cultured species productivity, 70-day FCR ratios, disease frequency, feed intake intensity, TSS and TDS, feed digestibility, investment, and profit percent in both culture farms were examined from day one to day thirty. Dissolved oxygen levels were 7 ppm and 5 ppm, ammonia levels were 0 ppm and 1 ppm, TDS-TSS levels were 50-100 ppm and >200 ppm in Semi RAS and biofloc systems, respectively. On the 30th day of the culture phase, according to the data, Semi-RAS yielded 3.6kg/m3, while biofloc yielded 1.6kg/m3. Stress and microbial contamination were reduced in Semi RAS, while digestibility increased. Although the Semi RAS system costs more than Biofloc, farmers that use it can earn three times as much and have a greater profit percentage. According to our findings, Semi RAS technology offers aquaculture farmers more possibilities.
