EVALUATION OF PROBIOTIC BACTERIA AGAINST AEROMONADS SYNDROME IN COMMON CARP (CYPRINUS CARPIO L.) IN SIMPLE AXENIC LARVICULTURE

摘要

Evaluation of probiotics, Bacillus firmus and B. coagulans against Aeromonas hydrophila in axenic common carp larviculture was conducted. The highest egg hatching rate was obtained from the axenic system + probiotic bacteria (AP) (98.33%), followed byaxenic system (A) (96.67%); axenic system + probiotic + A. hydrophila (AC) (93.33%); non-axenic system (NA) (93.33%); and axenic system + A. hydrophila (AH) (83.33%). 100% survival rate (SR) was obtained from all treatments, except AH (90%). The highestweight (0.013g) was obtained from the A treatment, followed by AC (0.0127g), AP (0.0123g), AH (0.012g), and NA (0.005g). In conclusion, the axenic system can be used to improve common carp larviculture, and further use of B. coagulans and B. firmus wasable to control Aeromonads syndrome during the larviculture stage.
