Assessment Summary

View the details of the Council Recommendation for this project as part of the 2018 Research Project Status Review.

NPCC Assessment 2003-063-00-NPCC-20210302
Assessment Number: 2003-063-00-NPCC-20210302
Project: 2003-063-00 - Natural Reproductive Success and Demographic Effects of Hatchery-Origin Steelhead in Abernathy Creek, Washington
Review: 2018 Research Project Status Review
Approved Date: 12/20/2018
Recommendation: Implement
Comments: This set of projects [200303900, 200305400, 200306300 and 201003300] went through a policy review in 2017, and this review by the ISRP for progress. Studies to date have revealed that RRS between hatchery and naturally spawning fish can be reduced in a variety of ways. Because of this complexity, a more detailed conceptual framework is needed to predict how different species or populations will respond to hatchery supplementation and to allow managers to make better case-specific decisions. The ISRP believes that an updated synthesis is needed to make progress toward such a framework. They suggest that any new effort to synthesize results across the RRS studies should consider the history of hatchery influence prior to and
during each study. Many of the projects reviewed are expected to report their most valuable results over the next few years. At that time, an updated synthesis of findings will be especially valuable. The ISRP is reassured that the RRS studies are on track and that proponents are collaborating and sharing information effectively. The Council concurs and asks that the sponsors work together on a synthesis report to be submitted and reviewed by the Council and the ISRP ahead of the start of the 2021 Anadromous Habitat and Hatchery Review process.

Recommendation: Bonneville to work with the sponsors on a coordinated reporting of results as a “synthesis” review. Bonneville and the sponsors are requested to present this progress report/results to the Council and ISRP in summer of 2020; close to when these projects will be wrapping up, and ahead of the 2020 Anadromous Habitat and Hatchery Review.
