Scientific evidence to inform spawning practices at Fisheries and Oceans Canada salmon hatcheries in the Pacific region. : Fs70-7/2024-032E-PDF

"Release of Pacific salmon from hatcheries to support or enhance natural populations creates potential risks to the genetic integrity, genetic diversity, and fitness of wild salmon. Under Canada's Policy for Conservation of Wild Pacific Salmon, wild salmon are defined as salmon that have spent their entire lives in the wild and are the offspring of naturally-spawned parents. The genetic risks to wild salmon associated with hatcheries are mitigated and minimized through genetic management of broodstocks. The Fisheries and Oceans Canada (DFO) Salmonid Enhancement Program (SEP) currently uses guidelines developed in the 1980s to direct broodstock collection and spawning within their hatchery lines. In recent years there have been substantial advances in scientific knowledge regarding the effects of hatcheries on wild salmon. A review of the genetic management of broodstock guidelines is timely to ensure operations are consistent with current science advice"--Context, page [1].
