Evaluating Experimental Hatchery Rearing Strategies to Increase Puget Sound

The state of Washington, through the Puget Sound Partnership (PSP), is seeking a collaborative research contract to evaluate experimental hatchery rearing strategies for Chinook salmon in Puget Sound. The primary objective is to optimize tools available to salmon hatchery managers to improve Chinook abundance and resilience to variable ecosystem conditions. The contract, funded through the Environmental Protection Agency's National Estuary Program, will involve coordinating and analyzing data from seven Puget Sound hatcheries, conducting lab analyses of scale and otolith samples, and synthesizing research on variable rearing and release strategies for juvenile Chinook salmon. Key deliverables include quarterly progress reports, an interim synthesis report in 2026, a final report in 2027, and outreach activities to communicate findings to regional managers and the public. The contract opportunity was posted on November 13, 2025, with a proposal due date of December 1, 2025, and a planned contract period from December 10, 2025, through June 30, 2027.

The contract has been identified as a sole source procurement with Long Live the Kings (LLTK), a non-profit organization specializing in salmon conservation. LLTK was selected through a competitive Request for Information process, demonstrating unique expertise and direct access to the comprehensive dataset from participating hatcheries. The contract is valued at $166,598, with funding coming from federal grant award number CE-02J98701-0. No specific set-aside designations or restrictions on respondent types were explicitly mentioned in the documentation. The project requires advanced scientific and analytical capabilities, particularly in marine ecosystem research, salmon biology, and data synthesis. The research aims to provide critical insights into how different hatchery release strategies impact salmon survival, size-at-age, and marine survival, with potential broader implications for salmon conservation efforts in the Puget Sound region.
