Modern shrimp aquaculture began in 1933 in Japan with the induced spawning and hatching of Marsupenaeus japonicus larvae.

This technology allowed the production of shrimp larvae in hatcheries instead of using larvae from the wild to stock grow-out ponds. Shrimp farming is an important activity in several low-income countries in Asia, America and Africa as it generates employment and wealth.

Nonetheless, intensification of shrimp culture increased the appearance of infectious diseases due to deviations in environmental and physiological factors. Infectious diseases caused by viruses or bacteria represent the biggest threat to development of shrimp farming due to high mortalities.

Pathogens that have caused severe epizootics and high mortalities to different stages and species of shrimp include Baculoviruses, Parvo-like viruses, Dicistrovirus, Ronivirus, Nimavirus and more recently, a bacterium, Vibrio parahaemolyticus
