Culture of prawn in rotation with shrimp

A progressive farmer in Tamil Nadu state, India experimented with crop rotation and successfully cultured Penaeus monodon during the dry season and Macrobrachium rosenbergii during the wet season. The details of M. rosenbergii culture are discussed in this article. Rotation with M. rosenbergii did help the farmer overcome the disease problem since farmers who exclusively cultured P. monodon in the nearby areas during the same season suffered losses due to white spot disease.
