Tilapia Parvovirus

  • India has witnessed its first encounter with Tilapia Parvovirus (TiPV), in Tamil Nadu
    causing a significant impact on the country’s aquaculture.
  • This virus has been reported in farm-bred tilapia, a freshwater fish species, and has
    raised concerns due to its high mortality rates.
  • TiPV is a viral pathogen that primarily affects tilapia.
  • It belongs to the Parvoviridae family, known for its small, non-enveloped, singlestranded DNA viruses.
  • First reported in China in 2019 and Thailand in 2021. India is the third country to report
    the occurrence of TiPV.
  • TiPV has caused mortality rates ranging from 30% to 50% on fish farms.
  • In laboratory settings, it has led to 100% mortality, highlighting its devastating impact.
  • TiPV outbreak can also pose a threat to the biodiversity and ecology of freshwater
    bodies as tilapia is an invasive species that can compete with native fish for food and
  • TiPV outbreak can also affect the food security and nutrition of the people who depend
    on tilapia as a source of protein and income.
