Abstract
In recent years, culture of Macrobrachium rosenbergii is expanding in India and West Bengal state in particular, due to its relatively fast growth rate, high market price and export demand. However, the detail study on parasitic diseases has received less attention on cultivable M. rosenbergii compared to the penaied prawns. The present parasitic survey on M. rosenbergii from coastal West Bengal state in India encountered 14 species of parasites. Among the protozoan parasites, Zoothamnium sp., Amphileptus sp., Dileptus sp., Chilodonella sp., Balladyna sp., Epistylis sp., Vorticella sp. and Gregarina sp. were recovered; of which 4 were ecto-commensals and other 4 were endo-commensals. Metazoan parasites represented by Myxobolus sp., Rhabdochona sp., Indocucullanus sp., Procamallanus sp., Cucullanus sp. and Acanthogyrus sp; of which 1 were ecto-commensals and other 5 were endo-commensals. In West Bengal state, inland culture and capture based fishery activities, mainly rural based, are operated by poor farmers. Developing the right kind of intervention and managemnt practice can prevent adverse impact of diseases and assist poor farmers for sustainable production. Key words: Macrobrachium rosenbergii, epibionts, parasites, West Bengal.
