What kind of fish should I use to control mosquito larvae in eastern Colorado?
Stocking of fish is controlled by the Division of Wildlife (DOW). DOW recommends against stocking Gambusia in eastern Colorado waters that contain native fish species or that are connected to waters containing native fish species because the Gambusia can displace the natives. Consider the alternatives such as fathead minnows, fingerling trout, and fingerling bluegill. Fingerling bluegills are recommended where sport fisheries exist.
