Bacteria from the gastrointestinal tract of the rabbitfish Siganus guttatus (Bloch, 1787) were isolated and screened for their potential as anti-vibrio agents. A total of four isolates based on colony dominance and morphology were selected and tested against Vibrio harveyi in cross-streak and co-culture tests. Although no inhibition was observed for all isolates in the cross-streak tests, a significant reduction was observed in the population of V. harveyi in coculture with all isolates. Reduction in V. harveyi population ranging from 63.9% - 100% were observed within 24 hours of inoculation. This study showed the potential of bacteria isolated from the gut of S. guttatus to act as a possible control agents against V. harveyi especially in cultures of shrimps and prawns wherein S. guttatus could be raised in tandem to produce “green water”.
