Virological research as an integral part of complex monitoring of fish diseases

Abstract

Abstract In the early 2000s, there were no russian test systems for detecting fish viruses, the work was carried out in cell cultures and in the neutralization reaction, which is effective, but the result was obtained no earlier than 10 days, simultaneously with the release of the virus in the cell culture, which undoubtedly increased the time of diagnosis. In 2009, the addition of existing methods to polymerase chain reaction and enzyme linked immunoassay methods made it possible to detect not only open forms of the disease, but also virus carriers, which is the most important information in the organization of cross-border transport of hydrobionts. Systematic comprehensive diagnostic studies in fish farms have allowed us to get a clear idea of the epizootic situation and identify areas of trouble for viral fish diseases and take timely measures to stop the disease.
