Dinakaran GK, Soundarapandian P and Varadharajan D

Shell disease may also be referred to as black spot, brown spot or spot disease and was recognized early this century as a problem in impounded population of aquatic animals. The chitinoclastic bacteria which cause shell disease are ubiquitous and infect a wide range of crustaceans, including prawns. All wild and cultured prawns are susceptible to infections; however disease rarely in wild crustaceans due to a lack of overcrowding and less mechanical damage. In the present study the Tail rot disease noticed in the M. idella idella (prawn), which is not common for prawns. The tail rot diseased prawn was tested to bacteriological for enumeration, isolation and biochemical identification of the microorganism.
