The present study investigated the level of WSSV
transmission from the infected tiger prawn P. monodon
to SPF L. vannamei in the WSSV impact region of Tamil
Nadu coastal waters, in connection to PCR detection and
histopathological observation. And survey of WSSV affecting
and non-affecting zone and detection of environmental
water samples with appropriate infected shrimp sample were
carried out. Detection limitation is followed with molecular
based diagnosis dealing with nested PCR and histopathology
analysis. In an effort to reduce the accidental introduction
of non-native organisms (including pathogens), guidelines
has to be established to assist governments and the private
sector in importing non-native aquatic organisms for fishery
or aquaculture use in a responsible manner.
