| In aquaculture, the use of new technologies such as biofloc, aquaponic and synbiotics has increased the efficiency of aquatic animal production. In this study, five culture systems as experimental treatments, 1-biofloc (B), 2-biofloc and synbiotic (BS), 3-biofloc and aquaponics (BA), 4-biofloc, aquaponic and synbiotics (BAS), and 5-aquaponic (A), were designed for growth of giant shrimp, Macrobrachium rosenbergii, post larvae. The growth indices and water quality parameters were measured and compared among the experimental treatments. The highest total body length was observed in treatment BS (74.28±18.63 mm) and had a significant difference compared to other treatments (p≥0.05). The highest concentration of ammonia was related to treatment A (0.77±0.22 mg/L) and the lowest was recorded in treatment BAS with the rate of 0.61±0.16. Nitrite had the highest rate in treatment BS, (8.01±7.08) and the lowest recorded in treatment BA (6.47±6.55). The nitrate had the highest rate in treatment BAS, with the rate of 6.11±5.52 and the lowest recorded in treatment B with the rate of 4.29±4.09. The results of this study indicated that using biofloc, aquaponics and synbiotics, in a culture system, increase the efficiency of culture system in production of freshwater giant shrimp. |
