Disease is one of the major factors affecting the development and sustainability of aquaculture. White spot disease caused by white spot syndrome virus (WSSV) results in severe production and economic losses to the shrimp farming industry worldwide. Recently, Hepatopancreatic microsporidiosis caused by Enterocytozoon hepatopenaei (EHP) a microsporidian parasite has been reported to cause severe growth retardation and losses in commercial Penaeus vannamei farming. In the present study, we report the prevalence of white spot syndrome virus and hepatopancreatic microsporidiosis in the P. vannamei shrimp farms in Nagapattinam district, Tamil Nadu, India. This study was undertaken in a total number of 57 selected P. vannamei farms in Nagapattinam district, Tamil Nadu during the period from October 2016 to September 2017. P. vannamei samples collected at fortnight intervals were screened for WSSV and EHP by PCR. The results showed that the prevalence of diseases caused by WSSV and EHP were 49.12% and 66.66% respectively. This report alerts the farmers for the adoption of better management practices to be followed so as to prevent these diseases and improve the production and sustainability in P. vannamei farming.
