White spot syndrome virus (WSSV) is a strong pathogenic virus which spread very rapidly and can cause tiger shrimp mass mortality within a short period. Enhancement of shrimp immunity by infecting inactivated WSSV is one of the efforts to overcome WSSV infection in shrimp. In this study, inactivated WSSV were prepared by heating them with various temperatures namely 45, 50, 55 and 60oC for 30 minutes. The results shows that infection with heating inactivated WSSV at 45C and 60C for 30 min on PL-15 could increase their immunities. The survival rate of inactivated WSSV-infected shrimp after challenge test with WSSV virulent reached 77%, while no survive shrimp was observed in control. This suggests that shrimp immunity could be improved by vaccination using WSSV virus inactivated by heating.
