Three groups of black tiger shrimp (Penaeus monodon) post larva, infected with MBV (Monodon Baculovirus) at different levels including less than 20 percent, between 20-50 percent and more than 50 percent were used to stock into the culture pond. MBV infection in normal and abnormal growth shrimp were determined at 40, 80 and 120 days post stocking. The relationship between the different rates of MBV infection in post larva at the time of stocking and the growth of shrimp at harvest were also studied. The results revealed that there were no relations between the different rates of MBV infection in post larva and the MBV found in shrimp with different growth rate during culture and at the time of harvested. Therefore, the method used for MBV determination in post larva for this study may not be sensitive enough. This may due to the number of post larva used for the test were not represent the population. The other possible is MBV may not be the primary cause of stunt problem in black tiger shrimp.
