Is Gambusia affinis used as part of mosquito control operations?

Gambusia affinis, commonly known as the mosquito fish, is indeed used in mosquito control operations primarily because it is effective in controlling mosquito larvae. This fish preys on mosquito larvae in various freshwater habitats, making it a natural and environmentally friendly biological control agent. By introducing Gambusia affinis into ponds, marshes, and other water bodies where mosquitoes breed, the population of mosquito larvae can be significantly reduced, thereby helping to control the overall mosquito population. This method is often preferred over chemical control options since it helps maintain ecological balance and reduces chemical usage in the environment.

The other options do not accurately depict the role of Gambusia affinis in mosquito control. For instance, it does not target adult mosquitoes, is effective in freshwater rather than saltwater habitats, and is recognized for its efficiency in larval control rather than being ineffective.
