JACKSON –As county fairs, where goldfish are often given as prizes, conclude, the Wyoming Game and Fish Department is reminding the public about the impacts of releasing pet fish into local waterways.

While it may seem harmless, releasing goldfish and other exotic species into the environment carries significant ecological risks and is unlawful under Wyoming statutes and regulations. Goldfish are resilient; they can not only survive Wyoming’s harsh winters but also reproduce rapidly, creating nuisance populations that are difficult to manage. By aggressively competing with native species for food and resources, goldfish disrupt aquatic ecosystems and can introduce harmful diseases.

"The introduction of non-native species threatens the health of local waters and diverts resources that should be focused on protecting the region’s native species," said Darren Rhea, Jackson Regional Fisheries Supervisor. “Given the serious impacts an illegal fish introduction can have on a fishery, this crime carries some of the highest penalties that exist for wildlife violations."

If you find yourself with a goldfish you can no longer care for, please follow the C.A.R.E. guidelines found on the Game and Fish “Don’t Let It Loose” webpage.

Community members are encouraged to report any sightings of goldfish in local waters. For reporting or additional questions, contact the Jackson Regional Office at (307)-249-5827.
