Mosquito larvae can be a potential vector, responsible for severe outbreaks of malaria, dengue, bancroftian filariasis and arboviral infections. Various methods have been tried and many more still being developed to eliminate or reduce mosquito population. Environmental concerns surrounding the use of chemical methods to control mosquitoes have led experts to explore more eco-friendly alternatives. One promising approach involves biological control methods, which aim to manage mosquito populations through the introduction or enhancement of natural predators, parasites, or disease-causing organisms. These natural enemies help to keep mosquito numbers in check while minimizing environmental impact.
The present study focused on using Ornamental fishes as predators of mosquito larvae and the rate at which mosquito larvae were consumed as well as the other feeding preferences of five ornamental fishes (Betta, Angel, tiger barb, guppy, rasbora) were noted and compared. The rate of consumption was noted between 47-60 larvae per fish per day. While all of the five fish groups consumed almost all the mosquito larvae given to them in presence of fish pellets, Betta sp. and Puntigrus sp. consumed a moderate amount of fish pellets whereas others’ consumption of fish pellets were nearly negligible.
