Title

EFFECT OF BIOFLOC TECHNOLOGY ON GROWTH PERFORMANCES, BODY COMPOSITION AND REDUCTION OF ECONOMIC COSTS IN INTENSIVE CULTURE OF COMMON CARP (CYPRINUS CARPIO) JUVENILES

Pages

  163-169

Abstract

 BACKGROUND: BIOFLOC TECHNOLOGY is considered a method that degrades organic waste by microorganisms and produces bacterial flocculation.OBJECTIVES: This study was performed to evaluate of the application of BIOFLOC TECHNOLOGY in the rearing of COMMON CARP (Cyprinus carpio) fingerlings in intensive culture.METHODS: The experiment was designed in four treatments (Commercial diet as a control, 75% commercial diet+Biofloc, 50% commercial diet+Biofloc, 25% commercial diet+Biofloc) with carp fingerlings (Initial weight 58±2 g) over a period of one month. Water exchange in Biofloc treatments was 1% during 24 h while water flow through system was used in control. At the end of experiment, all fish were intraperitoneally injected with 12´107 colony forming units (CFU) of Aeromonas hydrophila per fish.RESULTS: The results of the experiment indicated that the highest weight gain was observed in fingerlings fed 75% commercial diet+Biofloc that differed significantly from the group fed 25% commercial diet+Biofloc (p<0.05). There was no significant difference between control and 50% and 75% commercial diet as well (p<0.05). No significant difference was observed in case of condition factor, viscerosomatic index (VSI) and survival in experimental treatments (p>0.05). Also, Biofloc significantly increased ash content in muscle (p<0.05). The highest mortality (64.2%) was observed in control in challenge of Aeromonas hydrophila.CONCLUSIONS: The results suggest that the BIOFLOC TECHNOLOGY can increase growth performances of carp fingerlings in INTENSIVE SYSTEM and decrease water exchange via quality improvement.
