Abstract:
The present study revealed the importance of marine actinomycetes as a potent source of
bio active secondary metabolites. The selected isolates were capable of protecting Peaneus
monodon against WSSV infection. They also proved to be inhibitory to vibrios and
is a rich pool of hydrolytic enzymes. Their capacity to proliferate in saline environments
and their property of non-pathogenicity to prawns makes them good candidates to be applied
as probionts in penaeid shrimp aquaculture. They also enhanced the immune status of
shrimps challenged with WSSV and act as a good source of antioxidants. Exploitation of
the potential for the prophylactic and therapeutic measures in aquatic animal health management
would be highly rewarding. This work is a preliminary study targeting marine
actinomycetes as a source of antiviral compounds and as probionts in Penaeus monodon
culture systems. More work is needed to understand the nature and mode of action of the
bioactive compound, the various aspects of immune and antioxidant responses under challenge
and when exposed to pro active treatments, and the dose and frequency of application
of such compounds under rearing conditions.
