A Survey of Shrimp Diseases in India
Abstract
To develop a database of diseases affecting shrimp in
India, an investigation was carried out in shrimp farms and hatcheries
throughout the Indian coast over a period of two years. Diseases frequently
encountered were luminescent bacterial disease, larval mycosis, protozoan
infection, black spot disease, tail rot, muscle necrosis, vibriosis, P.
monodon - type baculovirus (MBV) and systemic ectodermal and mesodermal
baculovirus (SEMBV) infection or white spot disease. Also observed were
infections of yellow head virus (YHV) and infectious hypodermal and
haematopoietic necrosis virus (IHHNV). A survey of antibiotic resistance was
simultaneously carried out on bacterial cultures isolated from diseased shrimp,
and remedial measures were suggested. This paper also deals with the incidence
and outbreak of white spot disease in India and its recurrence after a crop
holiday period of 4-5 months.
