Southwestern Native Aquatic Resource
and Recovery Center
Southwest Region

Species on Station

The Southwestern Native Aquatic Resources & Recovery Center currently holds 14 threatened and endangered species. The Center has a viable and protected captive gene pool of these imperiled fish native to the Southwest. The station maintains a broodstock for each species, rearing fish with the intent of reintroducing them into their native habitat.

The Center contributes to the recovery of each fish by providing a refugium, developing propagation and culture techniques, conducting water quality data, diet and nutrition testing, early life history studies, reproductive physiology and genetic management.

The area of research and development has been expanded and the Center houses the largest number of threatened and endangered fish species of any facility in the United States.
