Description The loss due to diseases in the aquaculture sector is estimated to be around 10-15% of the production cost
and it can be substantially reduced if due attention is given to scientific health management. Most of the
antibiotics are banned in aquaculture, so the alternative to maintain fish health is based on the supplementation
of probiotics, immunostimulants and administration of vaccines. The main objective of developing a multivalent
vaccine against vibriosis is to prevent the seasonal epizootics in cultured cobia Rachycentron canadum. The
whole cell inactivated multivalent vibrio vaccine against vibriosis was developed, standardized and evaluated
in cobia fingerlings. The field application of the vaccine was studied in sea cages deployed for growout and
broodstock rearing of cobia. The immune responses were evaluated by challenge studies in fingerlings and
serum antibody titre in cobia growout and broodstock cages using ELISA. The regular epizootics observed in
cage cultured cobia, every year during the months of July to September (pre-monsoon season) was prevented
by timely vaccination and proper sea cage farming management.
