Breed guppies and bid goodbye to dengue

Guppy fish can get rid of the Aedes aegypti mosquito that spreads the dengue virus. This freshwater fish is Enemy No 1 of these mosquitoes and, if properly deployed, can eliminate the mosquitoes. The guppy fish grows to little more than the size of the index finger and the two-inch guppy, in the opinion of public health experts, is a cheap and effective weapon in the fight against dengue and malaria.
This has been reported in telegraphindia.com dated 2 November 2016.

These fish are usually found in small ponds and pools and also in brackish water and can live for up to five years. The guppy fish feeds on microbes and mosquito larvae and one of then devour 25 to 50 larvae in 24 hours. Hence, municipalities struggling to destroy breeding grounds of the Aedes aegypti must ensure that the guppy's voracious appetite for larvae is met.
Incidentally, the dengue-causing Aedes aegypti mosquito breeds in fresh, stagnant water and the guppy fish too prefers to live and breed in fresh water. If a reservoir has 10 to 20 guppy fishes, within a year the population can shoot up to 2,000!
