SPRINGVILLE, Utah (AP) -- Utah officials say they'll kill 60,000 tiny trout after finding evidence of the parasite that causes whirling disease at the state hatchery in Springville.
The hatchery will be closed until a new water supply is found.
The discovery was made last week during routine testing of the young rainbows. The four-inch fish were not stocked in Utah waters.
Whirling disease affects trout and salmon, resulting in deformations and neurological damage.
The Division of Wildlife Resources says the infected fish are a small fraction of the fish raised in state hatcheries.
