The disease control programmes in aquaculture must include examination of diseases and mortalities in holistic manner and consider various factors such as stocking densities, environment (turbidity, temperature, pH, salinity, dissolved oxygen of water and redox potential of soil), rate of water exchange, presence of bottom dwelling algae, the type of feed and its rate of consumption by the shrimps, phytoplankton bloom, physiological status of shrimps, etc. Thesse factors considered together go on long way in management of disease problems. Most of the disease control methods are based on preventive measures. They are : 
Quarantine measures  

Use of genetically resistant stock for culture purpose  

Use of prophylatic vaccines  

Use of drugs
