We all know that Pistias tratoites is a well-known freshwater weed and because of its rapid growth major freshwater resource i.e. rivers getting polluted. In other hand different animal species lives inside of water getting harm and struggling for surviving purpose. Goldfish was imported into laboratory as a potential biological control agent for the floating aquatic weed Pistia stratoites. Quarantine studies demonstrated that this fish was actually feeding on P. srartoites. On primary level fish was released into the culture of P. stratoites in laboratory for under observation. The fish was used for first time in India as a biological control on P. stratoites. It was observed that the goldfish actually feeding on freshwater floating weed P. stratoites. The result is discussed in relation to its effectiveness. I concluded that goldfish effectively controls the growth of P. stratoites by feeding on it in tropical region (22°C) but in cooler region its effectiveness may be fluctuate with seasonal conditions.
