Betanodavirus, commonly called nervous necrosis virus (NNV) of fish, has emerged as a major constraint on marine aquaculture worldwide. Here, we report the complete genome sequence of a betanodavirus (strain CsCN128) isolated from diseased half-smooth tongue sole (Cynoglossus semilaevis) in China. The genome sequence of strain CsCN128 shares ≥98.7% similarity with seven-band grouper nervous necrosis virus from Japan. Phylogenetic analysis indicates that strain CsCN128 belongs to the red-spotted grouper nervous necrosis virus (RGNNV) genotype of betanodavirus. The genome of the strain CsCN128 will facilitate further study on the molecular epidemiology and natural susceptible host range of betanodaviruses.
