| Summary: | Abstract
The objective of this research was to know the effectiveness of polyvalen Vibrio vaccine to control vibriosis in humpback grouper (Cromileptes altivelis). The effectiveness of vaccine was evaluated by the survival rate (SR), relative percent survival (RPS), mean time to death (MTD) as well as growth rate of vaccinated fish. This research consisted of 4 treatments (control. injection, immersion, and oral vaccinations) in guadruplicates.,Injection vaccination was conducted by intraperitoneal injection of polyvalen vaccine at 10' cells/fish. Immersion vaccination was done by immersing the fishes at 10' cells/ml for 30 minutes. Oral administration of vaccine was also carried out at 107 cells/fish. One week after the first vaccination, second vaccination (booster) was carried out at the same dosage and by the same administration. One week after the second vaccination. fishes were challenged with 3.16x104 cells/fish of Vibrio ordalii 3J by intraperitoneal injection, and reared for 20 days post infection. Results indicated that polyvalen Vibrio vaccine increased SR (P |
