Abstract
Biofloc technology is a technique of enhancing water quality in aquaculture through balancing carbon and nitrogen in the system. The aim of this study was to determine the effects of biofloc technology in intensive culture of common carp fingerlings. Two groups of fingerlings (1-3 and 16-22g) were cultured in 45L tanks for 21 days. For each group, three following feeding treatments were assigned: 50% commercial diet (CD) + biofloc products, 75% CD + biofloc products and 100% CD as a control. Growth performances and physico-chemical parameters of water were measured and the results indicated that the fish fed with 50% CD + biofloc products show high percent weight gain than other treatments in first group (P > 0.05). But no significant difference was observed in case of growth performances in second group despite of decreasing in feed intake in bioflocs treatments. Also the results showed that application of biofloc system in intensive carp culture decrease concentration of ammonia, nitrite and nitrate despite of no water exchange (1% daily) in these treatments whiles water was exchanged at a rate approximately every 10 min in control. The results suggest biofloc technology seems to be efficient for intensive farming of common carp.
