Map of Mammoth Spring National Fish Hatchery:
- 1. Aquarium
Mammoth Spring NFH maintains an award-winning aquarium which is open daily to the public. Displays include fish raised at this hatchery and avariety of other interesting species.
- 2. Public Restrooms
- 3. Hatchery Office
This is the headquarters for hatchery activity, and someone is generally available at this location. Assorted hatchery information and brochures may be obtained here.
- 4. Raceway Area
Fish are held here for various production purposes. Packedcolumn aerators are used to add oxygen and help eliminate nitrogen from the water.
- 5. Culture Building
Fish are held here for various production purposes. The building is used for hatching fish such as striped bass and paddlefish, and for formulating specialized feeds for fish on artificial diets. The building is also home to the freshwater mussel lab, where a living stream tank provides habitat for the mussels, and an array of small tanks house host fish involved in the mussel research.
- 6. Rearing Ponds
Ponds are used for fish production during the summer growing season, and may be dry between harvests. During the winter most ponds are drained which helps eliminate harmful disease organisms and undesirable vegetation. All of the ponds that have water in them usually contain fish; however, many are small fry or fingerlings that are hard to see. Likewise, larger fish generally stay in deeper water and may not be visible.
- 7. Private Residence
Hatchery personnel only.
- 8. Spring River and Warm Fork River
You may enjoy excellent fishing opportunities in Spring River adjacent to the hatchery (please follow state fishing regulations).
