Resumen

The infectious pancreatic necrosis virus (IPNV) is a highly pathogenic virus that affects the aquaculture of rainbow trout (Oncorhynchus mykiss) and can cause mortality rates that exceed 90% in the juvenile stage. This study aims to know the distribution and frequency of IPNV presentation in trout production farms in the seven main producing states of the species in Peru. Prevalence values of IPNV have been identified in the states of Cusco (4.05%), Puno (3.81%), and Huancavelica (0.23%). These results showed the distribution and epidemiology of the IPNV that, until 2019, was absent in the country. Likewise, it represents the need to implement prevention and control measures against the virus to reduce the risk of dissemination to free states of IPNV. Finally, improving sanitary management against IPNV reduces its economic and productive impact on rainbow trout aquaculture in Peru.
