   Do hatchery fish affect wild populations?

   • The ecological impacts of hatchery fish on wild populations have been reviewed by Weber and Fausch ( 2003) and Kostow ( 2009 ). Large releases of hatchery fish can increase competition with wild fish and increase density-dependent mortality. Hatchery fish may also exhibit different behavior than their wild counterparts.

   Why is genetic management important for hatchery-origin fish?

   • Proper genetic management of and spawning strategies for hatchery-origin fish are critical to maintaining genetic diversity, minimizing inbreeding, maximizing effective population size, and reducing artificial selection (see the Fish et al. and Kozfkay et al. abstracts in Supplement B).

   Do hatchery-origin fish contribute to natural resource management?

   • The American Fisheries Society (AFS) has routinely assessed the contributions of hatcheries to natural resource management and issued recommendations to guide natural resource managers in the best uses of hatchery-origin fish. For the past several decades, AFS has explored these issues in a formalized process at approximately 10-year intervals.

   Does hatchery rearing affect salmon survival?

   • However, hatchery rearing often results in reduced fitness and survival in salmon (Araki et al. 2007; Blouin et al. 2010; Fraser et al. 2011; Becker et al. 2014; Le Luyer et al. 2017 ), even after a single generation of hatchery rearing (Araki et al. 2007 ).
