About Gambusia fish
- Commonly known as mosquito fish, Gambusia fish is widely utilized as a biological agent to control mosquito larvae populations.
- Originally native to the waters of the south-eastern United States, it has been employed in mosquito-control strategies worldwide, including India, for more than a century.
- A single fully grown Gambusia fish can consume approximately 100 to 300 mosquito larvae per day, making it an effective natural predator.
- In India, Gambusia fish has been a part of various malaria control initiatives, including the Urban Malaria Scheme, since 1928.
- Despite its usefulness in mosquito control, the International Union for Conservation of Nature has classified Gambusia as one of the 100 worst invasive alien species globally, highlighting its potential negative impact on local ecosystems.
