Thirty million fish are produced annually. The hatchery is one of 65 national Federal Hatcheries and Fish Technology Centers operated by the U.S. Fish and Wildlife Service. Each category of fish is hatched and reared differently. Besides hatching and raising fish species native to the Missouri River Basin, the hatchery is continually looking for better ways to hatch and rear endangered species such as the paddlefish and pallid sturgeon. The endangered species areas are closed to the public for the protection of the fish.
Visitors are able to watch eggs hatching and fish being reared at the hatchery.
Visitors may also walk around the earthen ponds used to raise cool and warm water fish. The aquarium consists of 13 tanks containing nearly 50 native and non-native species of fish, reptiles and amphibians.
