Proceedings of the Predator-Prey Modeling Workshop : Workshop Proceedings May 16-19, 1989, University of Washington Friday Harbor Laboratory in Friday Harbor, Washington.

This report summarizes the results of a workshop held to receive expert advice and review existing Columbia River models that include juvenile salmonid predation components and, if warranted, recommend alternate modeling approaches. The workshop was limited to models or modeling approaches that may have practical application to the specific problems of increasing survival of juvenile salmonids in the Columbia and Snake rivers by reducing predation losses. The US Fish and Wildlife Service (FWS) and the Oregon Department of Fish and Wildlife (ODFW) under interagency agreements with the Bonneville Power Administration (BPA) conducted a multi-year study of the impact of predator populations on juvenile salmonids in the John Day Reservoir of the Columbia River. The studies were part of BPA's implementation of the Northwest Power Planning Council's (NPPC) Fish and Wildlife Program, designed to protect and enhance production of salmon as mitigation for losses caused by hydroelectric development. The FWS agreement with BPA includes provisions for refinement or development of models to understand the dynamics of predation on juvenile salmon as a basis for considering active intervention to reduce predation losses. The BPA sponsored the workshop that included a review of existing and proposed modeling approaches, identification of model development needs, …
