Gambusia holbrooki - (Baird & Girard, 1853)
Mosquito Fish

New-World native now widespread globally. Gravid female. York County, MD.

[edit] Overview

This is a plain-jane guppylike fish with a prodigious appetite for mosquito larvae. Well-meaning individuals and organizations have released it into local temperate and tropical waters around the globe in efforts to control disease-carrying mosquitos.

Unfortunately, it often competes directly with native species and is widely blamed for upsetting local population balances. Ironically, some biologists believe its impact on mosquito populations is questionable, as it also targets other organisms that prey on the mosquito larvae.

A very similar species is Gambusia affinis, also called the Mosquitofish.
