A new virus among Vannamei shrimps, Abdominal Segment Deformity Disease (ASDD) previously known only to Thailand and Vietnam, has been detected in India.
The virus was detected by the department of Marine Living Resources of Andhra University (AU) and had been affecting over INR10 billion (US$146 million) worth of shrimp every year, the Hans India newspaper reported.
A duel infection, Abdominal Segment Deformity Disease (ASDD) and microsporidian Enterocytozoon Hepatopenaei (EHP), has been affecting the growth and life of the Vannamei shrimps, according to the university's findings. Both the diseases were detected in brooders in Thailand and Vietnam in 2012, and found by AU domestically in 2015 and lately confirmed the diseases after several field tests.
“Some hatchery owners directly import from Hawaii and go into production without screening. “This could be one reason for spreading the diseases all over,” said Prof R. Janakiram of AU marine department.
