Whirling Disease

Help prevent the spread of Whirling Disease:

Thanks to a number of factors, including preventative efforts by anglers, Myxobolus cerebralis, the parasite that causes whirling disease in salmonids (trout, salmon, whitefish, grayling) is found in relatively few waters in Utah.

Anglers can help contain the disease by following a few simple procedures, outlined in the Division of Wildlife Resources brochure, Whirling Disease and Utah Trout: What Utah Anglers Need To Know:

  1. Clean all equipment of mud (boats, trailers, waders, boots, float tubes and fins) before leaving your fishing water. Thoroughly dry equipment in the sun, if possible, before reuse. If you are traveling directly to other waters, clean your equipment with a strong solution of chlorine bleach or use another set of equipment.
  2. Don't dispose of fish heads, skeletons or entrails in any body of water. Fish parts should be disposed of in the garbage, by deep burying or by total burning.
  3. Don't transport live fish between bodies of water. This practice could spread disease and is strictly illegal.
  4. If you observe the symptoms of whirling disease in fish (various deformities of the head, twisted spines, a black tail or fish swimming in whirling motions), or if you observe illegal fish stocking, contact your local Division conservation officer or call the Division's poaching hotline at 1 (800) 662-3337.

Anglers are strongly encouraged to follow these procedures when fishing at the following waters. The Division's Fisheries Experiment Station reports that these waters have tested positive for the whirling disease parasite:
