INFECTIOUS MYONECROSIS VIRUS (IMNV) IN PACIFIC WHITE SHRIMP, Litopenaeus vannamei IN INDONESIA
Abstract: The aquaculture
industry in Indonesia has been growing rapidly and plays an important role in
rural development and export earning. Penaeid shrimp culture in Indonesia has
become a leading export earning in fisheries sector. The main constraint encountered
with shrimp culture has always been associated with disease outbreaks,
especially, caused by viral agents. The Pacific white shrimp (Litopenaeus
vannamei) was unofficially introduced to Indonesia in 1999, and officially
approved by Indonesian government in 2001. By the end of 2007, the Pacific
white shrimp has been cultured in more than 17 provinces. The Taura Syndrome
(TS) disease was detected in Indonesia in 2002, and the disease is currently
found in at least 10 provinces. The Infectious Myonecrosis (IMN) is an emerging
disease for L. vannamei in Indonesia, first detected in May-June 2006, causing
significant mortalities in grow-out ponds. The IMN is characterized by an acute
onset of gross signs: focal to extensive whitish necrotic areas in the striated
muscle, especially on the distal abdominal segments and tail fan. White
necrotic areas become reddened similar to the color of cooked shrimp. The
outbreak resulted in elevated mortalities was initially associated with a
chronic course of persistent low level mortalities. Up to date, IMN was
detected in East Java, Bali, and West Nusa Tenggara provinces. This paper is a
brief review of the epidemiological study of IMN disease of Pacific white
shrimp in Indonesia: the status of outbreaks, surveillance, and disease
diagnosis, and control measures.
