The total viable bacterial count in the water of the control
treatment was significantly lower than that in the water of the
biofloc treatments (P < 0.05; Fig. 3A). The number of presumptive
vibrios in the shrimp intestines of the control treatment was
significantly higher than that in the shrimp intestines of the biofloc
treatments, irrespectively of the organic carbon sources used
(P < 0.05; Fig. 3B). There was no significant difference observed in
the total viable bacterial count and the presumptive Vibrio count in
the shrimp intestines and in the water, respectively, between the
different organic carbon source treatments.
