Abstract
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.
