Last year, the Wyoming Game and Fish Commission approved $17.5 million to begin research, development, and set-up for raising cool and warm water fish in Wyoming; the existing Speas Hatchery near Casper was selected for expansion. Walleye, Channel Catfish, Bluegill, White and Black Crappie, Largemouth Bass, Tiger Muskie, and Sauger will be produced there, enabling Game and Fish to produce a reliable and diverse supply of cool/warm water fish species for Wyoming's anglers and eliminating the potential of introducing an aquatic invasive species or prohibited fish pathogen into Wyoming.
