A small live-bearing fish found in mangrove creeks and brackish waters of the southern US and northern Mexico.
Genus Gambusia, family Poecilidae: several species, in particular G. affinis, widely introduced for mosquito control (also called mosquito fish)‘Dozens of small gambusia fish in each pool keep mosquitoes in check.’
- ‘The gambusia can retreat to the pool during dry periods and then re-colonize other areas as the water returns.’
- ‘If anything, the gambusias may be too small for the gar to bother with right now.’
- ‘He, who grew up on the north shore of Lake Maggiore, filled a fish pond in the back yard with water hyacinths and gambusias from Lake Maggiore.’
- ‘At the creek, I'd dip into current or up under the banks, for eels, small cats, suckers, and in the flow for dace, gambusias, and even small jack and perch.’
- ‘Surviving populations at Big Bend, which live in a single, protected pool, descend from three gambusias rescued from the declining population in 1956.’
- ‘Fish around in the lagoon include eels, gambusias and the springer great mullet.’
- ‘Native gambusias are the best choice for mosquito control; those desiring underwater color should invest a pittance in dime-apiece ‘feeder goldfish.’’
- ‘The gambusias were fine, and the vals I had (which I collected from a freshwater stream about 500 km from the sea) were growing faster than ever.’
- ‘The ESA was not enough to save two species of fish in Texas, the Amistad and San Marcos gambusias; a bird in Florida, the dusky seaside sparrow; or a fish in Maryland, the Maryland darter.’
