At the Council’s April 1, 2011 request, the ISRP reviewed a revised proposal for the Shoshone-Bannock Tribes’ Supplementation, Monitoring, and Evaluation Program (#2008-905-00). The proposal is called for in the Columbia River Fish Accords. The revised proposal is available at www.cbfish.org/Proposal.mvc/Summary/229. The proposal states that numerous populations of salmon and steelhead are at demographic risk of extinction, and the proposal’s purpose is to determine the utility of supplementation as a potential recovery tool. The project goals are to assess the use of supplementation to augment natural populations, evaluate effects on survival and fitness, and track relative reproductive success. They plan to compare fish population response over time in treatment (supplemented) versus control (unsupplemented) streams and in reference to baseline data.
The ISRP requests a response that provides more details on why this new supplementation evaluation project is needed and how it will be implemented. See the attached memo for the detailed review. This review should be considered with the ISRP’s concurrently released review of the Shoshone-Bannock Tribes’ Crystal Springs Hatchery Program Master Plan (ISRP 2011-17).
