Clinical signs of infected shrimps

  • White spots on carapace and last
  • abdominal segment
  • Body colour becomes pale
  • White spots on carapace and last

  • Body colour becomes pale

Mortality rate
Cumulative mortality of up to 100% within 3 -10 days after infection

Transmitted vertically by trans-ovum, consumption
of infected tissue (e.g. cannibalism, predation, etc.), and by water-borne routes. Dead and moribund animals can be a source of disease transmission.

Penaeus monodon, Marsupenaeus japonicus, Litopenaeus vannamei and Fenneropenaeus indicus
