Risk of Spread of Megalocytivirus pagrus1 (Infectious Spleen and Kidney Necrosis Virus) From Frozen Fillets

Journal of Fish Diseases, EarlyView.
ABSTRACT Infectious spleen and kidney necrosis virus (ISKNV) is a significant threat to global aquatic food security by causing large‐scale mortality in the aquaculture of tilapia (Oreochromis niloticus) and mandarin fish (Siniperca chuatsi). ISKNV is a genogroup of Megalocytivirus pagrus1, along with RSIV and TRBIV, and their recent listing as WOAH ...
