The first known use of Guppy fish in India for such prupose was done in 1908 when a British army officer who had suffered frequent mosquito bites brought the fish from England. The officer, remembered as Major Selvy introduced the Guppy to breed in water bodies surrouding the Army cantonment in Bangalore where he was posted. But despite more than a century of known use of the Guppy to control malaria, the government did not scale up such prevention. But now the Administration seems to wake up for the fight.
