In recent years, a number of diseases have been negatively effecting on shrimp aquaculture. More recently, Enterocytozoon hepatopenaei (EHP), a microsporidian parasite causes Hepatopancreatic Microsporidiosis (HPM) to be associated with white feces syndrome (WFS) and slow (retarded or stunted) growth in farmed L. vannamei (pacific white leg shrimp) in many of the shrimp growing countries in Asia, also in India. Numerous studies revealed that the pathogen causing significant economic losses to the shrimp industry. So, to evaluate the economical importance of this parasite on pond profitability, five (5) farm pond production effected by both EHP and white feces syndrome were compared with five (5) normally performed shrimp population with biosecured environment by adopting best management practices (BMPs). | Effect of microsporidian parasite Enterocytozoon hepatopenaei EHP on pond profitability in farmed pacific white leg shrimp Litopenaeus vannamei
