Featured Species

Warm Springs Fish Technology Center is working with federal, state, and agency partners to provide management support of inter-jurisdictional coastal and riverine fishes, such as Robust Redhorse, Lake Sturgeon, Pallid Sturgeon, and Brook Trout. The Southeast Conservation Genetics Laboratory is implementing research projects on numerous freshwater mussels, and threatened and endangered species such as the Spotfin Chub and the round rocksnail. The Cryopreservation Laboratory works on the collection, storage, and cryopreservation of sperm to provide a management tool for conserving genetic resources to enhance fisheries programs and reverse the population decline of threatened and endangered fishes. Currently, the Cryopreservation Laboratory is working with Pallid Sturgeon, Apache Trout, Gila Trout, and numerous aquatic species and freshwater mussels.

A pallid sturgeon swims along a rocky stream bed. The fish is long and slender, with whiskers and small ridges along its back and sides.

The pallid sturgeon was first recognized as a species different from shovelnose sturgeon by S. A. Forbes and R. E. Richardson in 1905 based on a study of nine specimens collected from the Mississippi River near Grafton, Illinois (Forbes and Richardson 1905). They named this new species...
