200750200 - Application of Innovative Acoustic Telemetry Technology to Underpin Statistically-Valid Survival Estimates for Chinook Salmon in the Nearshore Ocean Off the Mouth of the Columbia River
Sponsor: Pacific Northwest National Laboratory
Short description: The purpose of this project is to establish innovative methods that can enhance and expand into the nearshore ocean estimates of juvenile salmonid survival and migration patterns, especially for subyearling Chinook salmon.
Location: Mainstem/Systemwide province, Systemwide subbasin
Budgets: FY08: $447,928 | FY09: $84,752
Primary species:
Anadromous: All Anadromous Salmonids
Objectives
| Objective | Description | Subbasin plan | Strategies |
| 1. Survival Estimate Extension | 1. Extend the geographic range for estimating smolt survival through the estuary to near the mouth of the Columbia River | Migration/Passage Conditions for Anadromous Fish: “…evaluate the soundness and achievability of, and impact of ocean conditions on, these smolt-to-adult survival ratios.” | |
| 2. Study Design Assumptions | 2. Investigate key assumptions and logistical issues to support future studies designed to obtain robust survival estimates during early ocean residence. | Migration/Passage Conditions for Anadromous Fish: “…evaluate the soundness and achievability of, and impact of ocean conditions on, these smolt-to-adult survival ratios.” | |
| 3. Smolt Migration Patterns | 3. Describe smolt migration characteristics, including residence time in and exit points from the study area within 20 km off the mouth of the Columbia River. | Migration/Passage Conditions for Anadromous Fish: “…evaluate the soundness and achievability of, and impact of ocean conditions on, these smolt-to-adult survival ratios.” |
