This federal Cooperative Agreement award from the U.S. Geological Survey under the Cooperative Research Units (CFDA 15.812) program provides $162,852.83 to Utah State University (USU) for a 3-year project period from January 1, 2024 to December 31, 2026. The purpose of the award is to conduct research on red shiner populations and production of YY fishes for nuisance population control. Key activities include:

1. Determining if other red shiner populations share the same genetic markers concordant with phenotypic sex as the population used to develop YY broodstock.

2. Assessing potential pathologies that may result from estradiol-17 treatments used in the development of YY red shiner to support regulatory approval.

3. Continuing data collection and analysis on the impacts of estradiol-17 on red shiner health in the YY production process.

Expected deliverables include a report detailing the genetic similarities across red shiner populations, an assessment of estradiol-17 treatment pathologies, and continued data on the health impacts of the YY production process. USU will provide consultation and technical services to support these research objectives.
