Bonytail

bonytailBonytail is one of four native “big-river” fishes that were once common throughout the Colorado River basin.  Bonytail has a powerful, streamlined body and owes its name to the thin, elongated tail structure.  It feeds on invertebrates, small fish, and plant material.  Due to habitat modifications and the introduction of non-native fishes, bonytail is one of the most endangered species in North America today.  Presently, bonytail is maintained in the wild exclusively by hatchery stocking programs and Lake Mohave is one of two locations (Lake Havasu being the other) where this unique fish is found in the lower Colorado River.  Little is known about the life history of bonytail.  Aside from being occasionally caught by anglers, it is rarely encountered in the wild.  The last live bonytail capture in Lake Mohave occurred in 2005.  Since then, bonytail has only been found in stomachs of striped bass.
