Abstract:
Fenneropenaeus indicus could be protected from white spot disease (WSD) caused by
white spot syndrome virus (WSSV) using a formalin-inactivated viral preparation (IVP) derived from
WSSV-infected shrimp tissue. The lowest test quantity of lyophilized IVP coated onto feed at 0.025 g–1
(dry weight) and administered at a rate of 0.035 g feed g–1 body weight d–1 for 7 consecutive days was
sufficient to provide protection from WSD for a short period (10 d after cessation of IVP administration).
Shrimp that survived challenges on the 5th and 10th days after cessation of IVP administration
survived repeated challenges although they were sometimes positive for the presence of WSSV
by a polymerase chain reaction (PCR) assay specific for WSSV. These results suggest that F. indicus
can be protected from WSD by simple oral administration of IVP
