Abstract
White spot syndrome virus (WSSV) has been a big problem to the shrimp industry worldwide for almost a decade. To investigate the factors that could lead to WSSV outbreak, an observational study was done in a farm with 11 ponds stocked with WSSV free P. monodon successively within one month. Shrimp stocked in nine of the ponds were successfully harvested after 128 to 173 days of culture (DOC); in spite of the observed WSSV infection in 8 of these ponds between DOC 103 and 127. WSSV outbreak was experienced in three out of the 11 stocked ponds 3 to 6 days after WSSV was detected.
WSSV was detected in shrimp after exposure to more than 200 stresses. Exposure to more stress factors after WSSV infection could lead to an outbreak, with greater risk in younger shrimp. Factors considered as stressors are dissolved oxygen below 4 ppm, high (>32 oC) and low (
