Hybrid grouper fed with Vibrio harveyi strain VH1 (1 × 107 CFU/g feed) at 4% body weight according to the vaccination regime. Fifteen fish were randomly selected from each group every two weeks. Vibrio harveyi strain VH1 feeding group showed increased feed efficiencies.

| Vaccinated | 30.73 ± 0.92 | |
| Final weight (g) | Control | 208 ± 5.54 |
| Vaccinated | 248 ± 9.32 | |
| Average weight gain | Control | 177.3 g/fish |
| Vaccinated | 217.3 g/fish | |
| Survival (%) | Control | 65.1 ± 0.14% |
| Vaccinated | 79.75 ± 0.07% | |
| Total amount of feed given (kg) | Control | 688.8 ± 13.22 kg |
| Vaccinated | 890.4 ± 18.99 kg | |
| Feed efficiency | Control | 7.39 ± 0.08 g feed/g growth |
| Vaccinated | 3.10 ± 0.09 g feed/g growth |
