Microsporidian Disease Confirmed

 

In 2015, shrimp farmers began noticing that their shrimp were not growing as fast as in previous years.  Now, a team of scientists at the Central Institute of Brackishwater Aquaculture (CIBA), led by CIBA Director K.K. Vijayan, has identified Enterocytozoon hepatopenaei (EHP) as the parasite that has been causing the growth retardation.  The parasite appears to be spreading from contaminated water or soil.

 

The parasite multiplies in the cells of the shrimp’s hepatopancreas (digestive gland) and impedes the process of food digestion, resulting in slow and stunted growth.  Though the infection does not cause death, productivity is significantly reduced, resulting in economic loss to farmers.

 

CIBA is organizing a national consultation with all stakeholders including scientists, policy makers, regulatory bodies, aquaculture professionals, hatchery operators and shrimp farmers to discuss a strategy for dealing with the disease.

 

EHP has been reported in China, Indonesia, Malaysia and Vietnam.  A disease surveillance carried out by CIBA indicated that of EHP occurred in more than 15 of the 100 farms that were investigated.
