Utah Project

Carp Feminization Trials for Invasive Population Mitigation

December 2023 - December 2025


Participating Agencies

  • Western Association of Fish and Wildlife Agencies

Problem statement: Competition and predation from nonnative fishes have substantially impacted native fish populations across the United States. Common Carp Cyprinus carpio are among the most invasive species due to their negative impacts on native fish communities and aquatic ecosystems.

So What? Why this research matters: Traditional removal efforts to extirpate invasive Common Carp populations are ineffective. Developing alternative population mitigation strategies, such as the Trojan Sex Chromosome strategy, need to be investigated for the potential control of invasive Common Carp populations.

Partners: The project is a collaboration of researchers across multiple State natural resource agencies that comprise the Western Association of Fish and Wildlife Agencies.

Research that informs decisions: Critical data will be collected on the development of optimal feminization strategies for Common Carp. This information is critical in the implementation of a Trojan Sex Chromosome eradication strategy that may be able to extirpate invasive Common Carp populations.
