The federal Cooperative Agreement award from the Department of the Interior's Fish and Wildlife Service, under the Central Valley Project Improvement Act (CVPIA) program (CFDA 15.648), provides $117,500.00 to CAL Poly Humboldt Sponsored Programs Foundation (HSU Foundation) to utilize environmental DNA (eDNA) techniques to improve the understanding of juvenile Chinook salmon rearing patterns in the Sacramento River system. By analyzing filtered water samples using quantitative PCR assays, the project aims to identify areas where juvenile salmon reside beyond their traditionally recognized natal habitats. This non-invasive approach supports broader efforts to enhance fisheries management and habitat assessment, contributing to a better understanding of habitat connectivity within the Sacramento River watershed. The project is scheduled for completion by June 30, 2026.

The detection of non-natal rearing of chinook salmon in the sacramento river using environmental DNA project utilizes environmental DNA (edna) techniques to improve understanding of juvenile chinook salmon (oncorhynchus tshawytscha) rearing patterns in the sacramento river system. By analyzing filtered water samples using species-specific quantitative PCR (qpcr) assays, we aim to identify areas where juvenile salmon reside beyond their traditionally recognized natal habitats. This approach provides a cost-effective and non-invasive method for monitoring anadromous fish populations, supporting broader efforts to enhance fisheries management and habitat assessment. Given the migratory nature of chinook salmon, applying edna analysis offers a valuable tool for detecting their presence in different environments, helping inform data-driven decision-making regarding habitat utilization. This project aligns with ongoing scientific efforts to refine conservation and resource management strategies while contributing to a better understanding of habitat connectivity within the sacramento river watershed.
