>   This graph illustrates the number of wild and captive reared June sucker captured and released during annual spawning runs up the Provo River.

Scientists estimate that the current population of June sucker naturally produced in Utah Lake is fewer than 1,000 individuals. This is extremely significant considering there were millions in the early 1800s. Researchers have aged wild fish between 25 and 43 years, indicating that natural recruitment has not occurred in recent years.

Refuge populations of the June sucker have been established in protected locations throughout the state, where researchers learn about the fish's life history and habitat requirements. Fish reared in captivity have been introduced into Utah Lake to supplement the wild population and have migrated to the Provo River to spawn with wild June suckers.
