The June sucker, Chasmistes liorus, is a critically endangered fish endemic to Utah Lake and the Provo River, where it is now under protection. It is a member of the sucker family Catostomidae.
Unlike most other suckers, the June sucker is not a bottom-feeder. Its mouth is more rostrally-oriented, allowing it to collect zooplankton from the water. The fish is dark gray or brownish dorsally, with a white or slightly greenish belly. It can reach a weight of 5 lb and has a life span of over 40 years.
This species was once plentiful in its native lake. Some contributions to its decline include predation on its young by introduced species such as the common carp and walleye, pollution and turbidity, drought, alteration of water flow, and loss of some native vegetation.
Biologists have been rearing the June sucker in Red Butte Reservoir, and more recently in the Springville, Utah fish hatchery which had been closed due to an outbreak of whirling disease. As whirling disease does not affect June sucker, the hatchery was reopened to house the June sucker. After the June sucker grow to a certain size, they are released into Utah Lake to help build the population.
The June Sucker Recovery Implementation Program coordinates and implements recovery actions for the June sucker.
