Chennai: Researchers at the ICAR-Central Institute of Brackishwater Aquaculture (ICAR-CIBA) have developed a vaccine for finfish such as Asian Seabass (Koduva) and have transferred the technology to industry for commercial production. On Thursday, ICAR-CIBA signed a partnership agreement with Indian Immunologicals Limited, Hyderabad, to commercially produce Nodavac-R , developed for viral nervous necrosis in finfishes. Researchers said viral nervous necrosis, or viral encephalopathy and retinopathy, is an acute viral disease affecting several species of marine, brackishwater, and freshwater fishes.
The disease causes 100% mortality in larval and early juvenile stages, while infected adult fish will be asymptomatic but can transmit the virus to the offspring through eggs and gonadal fluids. CIBA developed the recombinant monovalent viral nervous necrosis vaccine for finfishes. “Viral nervous necrosis is a major threat to finfish aquaculture, as the causative agent, nervous necrosis virus, has a wide host range.
The vaccine developed by CIBA can prevent vertical transmission of the disease to the offspring and prevent mortality in fingerlings. The vaccine can play a significant role in controlling the loss due to viral nervous necrosis in India and other Asian countries,” said Kulpdeep K Lal, director, CIBA. India has the world’s second-largest aquaculture production with 12.
12 million tonnes. The industry suffers economic losses due to bacterial, viral, fungal pathogens, and parasites. At present, these infections are managed by anti-infectives and other conventional measures.
There is a growing need for better control measures against these infections as there is a concern about anti-microbial resistance and chemical-free food products. At present, there are no fish vaccines available in India on a commercial scale to prevent diseases in aquaculture.
