This study clarifies the effect of green water from Chlorella sp., Tilapia hornorum and the combination of the two organisms on the growth of luminous bacteria in a simulated shrimp culture environment. Results showed that the presence of Chlorella sp. (105 cells/ml) alone was not effective in the control of luminous bacteria in shrimp (biomass=80 g/m3) rearing water. The presence of T. hornorum alone (biomass=500 g/m3) was more efficient in controlling the growth of luminous bacteria than the co-existence of tilapia and Chlorella sp. Nevertheless, the presumptive Vibrio count was lowest in control tanks that had the highest shrimp survival rate, which was attributed to the presence of other micro-algae such as Chaetoceros, Thalassiosira, Navicula, Nitszchia, Melosira, and Fragilaria.
