Abstract
Huge economic losses occur due to incidence of
viral and other diseases in shrimp farms of India.
To make a quantified assessment of these losses, a
field survey of 1142 shrimp farms following a
statistical random sampling from nine coastal states
during the period 2006-08 was conducted. The gross
national losses in the country due to shrimp diseases
was estimated as 48717 metric t of shrimp valued
at Rs. 1022.1 crores, and employment of 2.15 million
man days. Epidemic seriousness among the diseases
was for White Spot Syndrome Virus (WSSV), Loose
Shell Syndrome (LSS) and combination of WSSV
and LSS, white gut and slow growth syndrome in
that order at national level. Additional price loss
was also recorded on account of poor quality of final
output like deformed organs, loose shell and muddy
smell. In some cases, farmers resorted to premature
harvest and hence the production biomass also
reduced coupled with price drop according to the
count per kg of shrimps.
