The Central Institute of Brackishwater Aquaculture (CIBA), Chennai has developed an indigenous vaccine named “Nodavac-R” for viral nervous necrosis (VNN) affecting several fish species.
- Viral nervous necrosis (VNN) is a serious viral disease affecting many marine, brackishwater and freshwater fishes resulting in 100% mortality in larval and early juvenile stages.
- The disease is caused by nervous necrosis virus (NNV). The new vaccine, Nodavac-R, developed by CIBA can be injected to fingerlings.
- The vaccine is safe and efficacious and can be used in all species susceptible to VNN such as milkfish, grey mullet, mangrove red snapper etc.
