Tennessee History

The Tennessee Cooperative Fishery Research Unit (TN CFRU) was established in 1972 as a partnership with Tennessee Tech University, the U.S. Fish and Wildlife Service, the Tennessee Wildlife Resources Agency, and the U.S. Geological Survey. The Tennessee Unit is one of 40 Cooperative Research Units around the country (and one of only four that is a "Fish-only" Research Unit). In its 43-year history, the Tennessee Unit has had four Unit leaders: R. Don Estes, Jim Layzer, Phil Bettoli, and Mark Rogers.
