【 摘 要 】
The aim of the study was to determine the growth performance and calculation of business profit of catfish in various densities using biofloc system. Catfish fingerlings, 8±0.2 g each, were used in this research. There were three treatments in various densities, i.e. P1: 1,100; P2: 1,200 and P3: 1,300 fingerlings/m3. After 4 months observation, the results showed that growth performance regression from P1, P2, and P3was Y (P1) = 7.66 + 30.7 X (r2 = 0.971); Y (P2) = 7.45 + 23.6 X (r2 = 0.996) and Y (P3) = 6.5 + 23.63 X (r2 = 0.996), respectively. The P1harvest time was achieved within 3 months; while P2and P3were 4 months. Total yield/tank in P1, P2and P3were 297.00, 295.29 and 309.52 kg, respectively. The calculation of business profit per tank per month of P1, P2and P3were 626,784.17; 399,058.77 and 351,793.65 IDR (Indonesian Rupiah), respectively. Meanwhile, result of R/C ratio of P1, P2and P3were 1.60, 1.5 and 1.4, respectively. Since the calculation of R/C ratios were ≥ 1, this culture method is considered feasible as a business.
