200304100 - Evaluate Delayed (Extra) Mortality Associated with Passage of Yearling Chinook Salmon through Snake River Dams
Sponsor: Northwest Fisheries Science Center
Budgets: FY07: $1,328,500 | FY08: $1,346,306 | FY09: $1,364,645
Short description: Determine if downstream migration through three Snake River dams and reservoirs results in extra or delayed mortality in Snake River yearling Chinook salmon smolts as hypothesized during the PATH process.
Final Council recommendation (Nov 2006)
Funding category: Expense
Recommended budgets: FY07: $979,817 | FY08: $979,817 | FY09: $979,817
ISRP final recommendation: Fundable
This is a high priority project that deserves funding. The problem addressed in this project is delayed mortality. This project addresses the lack of empirical experiments designed to quantify delayed effects associated with hydrosystem passage. The proposal refers to the ISRP Retrospective Report (2005) and the BiOp Remand as requesting similar research needs as those stated in this project's objectives. The overall objectives are clearly stated. The proposal states that the project will use smolt-to-adult return rates (SAR) of PIT-tagged yearling Chinook salmon smolts exposed to two different migrational experiences within the FCRPS to test the hypothesis of extra or delayed passage mortality. The response clarifies how the three treatment groups will be compared and what the implications of all comparisons are. Also, the response provided additional details on the estimation of standard error for the L/I ratio that is fundamental in determining target sample sizes. The proposal documented some other funded work in the area, and the response provided a more complete summary. Relationships to other projects were clearly identified in the response. The history of the project is briefly described by noting reasons for lack of progress. Although the project has recently started, the results have been reported, including a paper in Transactions of the American Fisheries Society. In summary, the sponsors of the proposal agreed with all of the ISRP review comments and recommendations and responded with appropriate and adequate revisions to the proposal.

State/province recommendation: MS: Core Program
Review group: MSRT
Recommended budgets: FY07: $1,328,500 | FY08: $1,346,306 | FY09: $1,364,645
Comment: Some MSRT members expressed concern about language in this proposal that indicated that this project may not be able to accomplish it objectives. This project is addressing a Core Program need; however, the MSRT needs the ISRP and other technical reviews for this project to determine if this project can accomplish its objectives.
