Shrimp farmers are advised not to stock shrimps during cold months (November-February). Mr. Vic Estilo, AQD shrimp pond culture expert said culture may be done during the warmer months from April to October, since shrimp get stressed when temperatures dip below 27°C, predisposing them to diseases. A study done at the Southeast Asian Fisheries Development Center/ Aquaculture Department (SEAFDEC/AQD) shows that drop of temperature weakens the immune response of shrimp making them prone to infection. The evidence the study showed is the pattern of outbreak of white spot syndrome virus in tiger shrimp (Penaeus monodon) when pond temperature is low.
