30 April 2021 Current Affairs:The Central Institute of Brackish Aquaculture, that is located in Chennai, has developed an indigenous vaccine for Viral Nervous Necrosis. The name of the vaccine is Nodavac-R.

Viral Nervous Necrosis:
♦ The sickness is prompted via the Betanodavirus. It generally impacts teleost fish. More than 40 species are affected by this virus, and most of them are marine species. This virus transmits via passive diffusion and contact. The ailment, more often than not, happens in juveniles or larvae. However, it also influences adults species.
♦ Viral Nervous Necrosis (India): In India, the disease has been a severe problem affecting freshwater, marine, and brackish water fishes largely. They result in 100% mortality in fishes that are in juvenile and larval stages.
♦ Red Spotted Grouper Nervous Necrosis Virus is the sole genotype located in India. The infected adults are the essential carriers. They transmit the virus to their offspring via the eggs.
Solution: The great way to control the disorder is to vaccinate adult fish and fingerlings. The Nodavac-R is secure for all species that are inclined to Viral Nervous Necrosis. They are to be used in fish hatcheries to carry down the incidence of the disease. Fish Hatchery is the vicinity for the artificial breeding of fishes.
♦ Teleost fish range from giant oars fish that measure 7.6 metres in size to minute Angler fish that measure 6.2 millimetres. They are economically significant. The Teleost fish are captured for meals all over the world.
♦ India ranks 2nd in aquaculture, and extra than 14.5 million Indians are established on fish production.
