Abstract

The impact of hatchery fish on native populations has been extensively studied, especially as environmental management has generally moved toward a conservation focus. In Oregon, the McKenzie River native rainbow trout population has been the focus of recent interest groups attempting to induce a change in management practices to support native fisheries. The McKenzie River Chapter of Trout Unlimited is interested in learning more about the impacts that hatchery stocked rainbow trout have on native river populations. It is the group's intent to seek a rule change to management by the Oregon Department of Fish and Wildlife. A review of the historical and scientific information regarding fish stocking was needed to provide information for Trout Unlimited to make informed recommendations to the managing agency. Examples of successful management changes for conservation of native fish were used as case studies to examine the implications of stocking cessation on the viability of trout populations in Oregon. This paper provides details on the background information needed to understand the case studies, their relation to the situation on the McKenzie, and how those outcomes may support recommendations for fisheries management on the McKenzie. It is the intent that these recommendations and supporting details may provide Trout Unlimited with the information needed to make a meaningful recommendation to the Oregon Department of Fish and Wildlife regarding the native rainbow trout fishery in the McKenzie.
