In India, the steady growth in freshwater aquaculture is led by the recent production of the Pangasius catfish. In fact, Andhra Pradesh, the fifth largest state in the country, is now know as the "Fish Bowl" of India for its rich production of pangasius.Catfish production is the fastest growing fish farming in the country's aquaculture sector; however it appears as the higher the production increases, the higher the risk for disease outbreak among the species.Under intensive production methods and poor cufture management, fish are exposed to stressful conditions leading to growth reduction and higher susceptibility to various diseases. Red disease often occurs during the change from the dry to rainy season and during the flood season.
