Title: Evaluation and Statistical Review of Idaho Supplementation Studies :1991-2001.

The Idaho Supplementation Studies (ISS) was developed to evaluate the utility of supplementation as a recovery tool for Snake River basin chinook salmon (Supplementation Technical Workgroup 1987), and to help define the potential role of supplementation in managing Idaho's anadromous fisheries (IDFG 1990; IDFG 1992). Supplementation as defined by the Regional Assessment of Supplementation Project group is the use of artificial propagation in the attempt to maintain or increase natural production while maintaining the long-term fitness of the target population (RASP 1992). Poor survival has led to the decline and continued depression of upriver chinook salmon stocks due to mainstem passage and mortality factors associated with the lower Snake and Columbia river dams. Although immediate efforts should focus on alleviating the poor passage and flow conditions, supplementation may concurrently be a viable tool to meet the Northwest Power Planning Council's interim goal of doubling anadromous fish runs in the Columbia River Basin (NPPC 1987) and avoiding short-term loss of spawning aggregates.
