Fish Species

current pub logo

The Dexter National Fish Hatchery and Technology Center (Center) currently holds 17 threatened and endangered species. The fish listed to the right are separated by family, common and scientific name.

The Center has a viable and protected captive gene pool of these imperiled fishes 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 Center is a pioneer in the area of research and development, and houses the largest number of threatened and endangered fish species of any facility in the United States.
