Bonytail (Gila elegans) is federally listed as endangered and considered functionally extirpated from its historical range, and its presence in the Colorado River Basin now relies entirely on stocking programs. Lake Havasu, Arizona, California, and Nevada, is one of the few release locations for hatchery fish and sites where stocked individuals are occasionally captured. Information regarding the basic ecology of this species is limited to past field observations and a small number of telemetry projects in the basin. The result is a lack of knowledge regarding how to better inform managers of the post-stocking fate and habitat use of hatchery-reared bonytail.
