Razorback Sucker fish

Razorback Sucker
The razorback sucker is endemic to the Colorado River basin and was listed as an endangered species in 1991. Populations are currently in decline throughout the Colorado River basin and have decreased markedly during the last two decades in the lower basin, particularly in Lake Mohave.

The razorback sucker roundup began in 1979 by Arizona State University to monitor the population and to gather life history information on this species. Today, this effort includes participants from Arizona Game and Fish Department, U. S. Bureau of Reclamation, National Park Service, Nevada Division of Wildlife, and the U.S. Fish & Wildlife Service, who gather for one week during March with four camps established on Lake Mohave, all dedicated to monitoring this fish.
