摘要

Kuruma shrimp, also called kuruma prawn or kurumaebi (Marsupenaeus japonicus) is one of Japan's most favored shrimps. A native to the Indian Ocean and southwestern Pacific Ocean from Japan to Australia, these tasty creatures are chiefly consumed bythe Japanese who utilize them in, among other things, a dish called dancing shrimp because the shrimps are served live. In Japan, live kuruma shrimp can fetch as much as 100 dollar per kilogram. A hardy adaptable variety of shrimp, kuruma shrimp were among the first shrimp species to be cultured. However, outbreaks of the white spot syndrome (WSS) have been causing serious mortality to kuruma shrimp culture in Japan since 1993. Production declined from 3020 metric tons in 1988 to 1500 metric tons in 1994. In 1993, about 80 percent of kuruma shrimp production loss in Japan was due to white spot syndrome virus (WSSV) infection. The loss was estimated to be US 20 million dollar. Other losses recorded were due to Vibrio, Fusarium, and other unidentified infections. WSSV can be easily detected by routine examination using 2-step PCR even in its early state of infection, but, it is highly pathogenic and can be easily transmitted either through vertical (spawners to eggs) or horizontal (from other crustaceans and shrimp to shrimp) mode of transmission.
