Bluehead sucker

Wyoming Game and Fish Department electrofishing rafts will be out floating the Snake on Wednesday to help a graduate student sample native bluehead suckers.

The operation is set for the stretch of the Snake between South Park and Astoria.

“We will be avoiding trout habitat as best as we can so this shouldn't impact fishing but we wanted to let you all know that we will be out there,” Game and Fish fisheries biologist Diana Miller said in an email notice.

Electrofishing is a nonlethal technique commonly used in fish surveys and research that temporarily stuns and incapacitates fish so they can measured, tagged or fitted with tracking equipment.

Bluehead suckers are a native species considered extremely rare in Wyoming, though they’ve been documented in the Snake River watershed’s Buffalo Fork, Gros Ventre, Fish Creek and Spread Creek drainages. They're listed among the most imperiled species in Wyoming’s State Wildlife Action Plan, and their existence is threatened by hybridization and predation from nonnative species, dams that have blocked migrations and irrigation diversions that have degraded habitat.
