The White Spot Syndrome Virus is the most economically devastating viral pathogen to global shrimp aquaculture production and has been proposed to be capable of infecting all decapod crustaceans including the European Lobster. The disease can cause many deaths in farmed prawns. Experimental studies were conducted by injecting or feeding white spot syndrome virus (WSSV) derived from infected shrimp, Penaeus monodon (Fabricius), collected from the south‐east coast of India, to five species of shrimp, two species of freshwater prawns, four species of crabs and three species of lobsters.
