TO STUDY THEEFFECT OF AMMONIA IN THE BIOFLOC SYSTEM BY USINGDIFFERENT CARBON SOURCES DURING THE GROW OUTCULTUREOFCOMMONCARPCyprinuscarpioFRY

Abstract

newline by using different carbon sources during the growth-out culture of commoncarp Cyprinus carpio fry newlineIn this Study 13 weeks feeding trial was carried out to evaluate the effects of different carbon sources (sugar beet molasses: SBM + BFT, sugar: (S + Wheat Flour) + BFT, Corn starch: CS + BFT) on water quality, growth To performance, for common carp fry. Results showed a significant difference in water quality parameters among different culture systems; CS + BFT had the lowest amount of Total Ammonia Nitrogen (TAN) at the end of culture period. The survival rate observe in different carbon sources was 87.67%- 89.34% and in control tank was84.5%. The fish weight was the highest in CS + BFT (35.16±0.45g) and in control tank was 24.56g±0.09g, which also Showing good growth and had the lowest significant feed conversion ratio. Overall, this study suggests that microbial flocs formed in corn starch based Bio-floc improve common carp growth performance and tanks water quality under zero water exchange and hence ensures sustai newline
