Factors that contribute to the ecological risks of salmon and steelhead hatchery programs and some mitigating strategies

Abstract

State and federal agencies in the United States annually release millions of hatchery salmon and steelhead into public waters. Many of the hatchery programs are located in areas where the wild populations are now listed under the U.S. Endangered Species Act (ESA) (16 U.S.C. §§ 1531–1544). These hatchery programs pose genetic and ecological risks to wild fish populations. Genetic risks occur when hatchery and wild fish interbreed and usually occur within a taxonomic species. Ecological risks occur when the presence of hatchery fish affects how wild fish interact with their environment or with other species and may affect whole species assemblages. This paper reviews some of the factors that contribute to ecological risks. Important contributing factors include the relative abundance of hatchery and wild fish in natural production areas, hatchery programs that increase density-dependant mortality, residual hatchery fish, some physical advantages that hatchery fish can have over wild fish, and life history characteristics that may make some species especially vulnerable to the effects of ecological risks. Many of these risk factors can be mitigated by management activities that reduce the level of interactions between hatchery and wild fish. This paper concludes by recommending twelve mitigation strategies that may be useful when agencies need to bring hatchery programs into compliance with the take provisions of the ESA.

I would like to thank the World Wildlife Fund, especially Laura Williams, and my Russian colleagues, Vladimir Belyeav and Sergei Zolotukhin, whose invitation and financial support for me to attend their conference, “Current Issues Facing Salmon Hatcheries in the Russian Far East” (Kamchatka 2006), and speak on the ecological risks of hatchery programs prompted me to write this paper. Also thanks to Douglas DeHart for providing valuable comments, insight and discussion.
