Salmon aquaculture and coastal ecosystem health in Chile: Analysis of regulations, environmental impacts and bioremediation systems (2009, background): “[30]), but in the marine environment escapes display similar body condition and feed on the same prey items as wild salmon [31].”
Performance of farmed, hybrid, and wild Atlantic salmon (Salmo salar) families in a natural river environment (2012, background): “The present study compared performance in the freshwater phase of the life cycle only, and although McGinnity et al. (2003) and Fleming et al. (2000) also included the marine stage, the results from the marine phase differed in their studies.”
AQUACULTURE AND OCEAN RESOURCES: Raising Tigers of the Sea (2005, background): “Depending on the location and species, harms include increased competition for mates, space, and prey (95–98) as well as reduced fitness of wild fish resulting from interbreeding with escaped farmed fish of the same species (96).”
Genetic assignment identifies farm of origin for Atlantic salmon Salmo salar escapees in a Norwegian fjord (2008, background): “It has been argued that the numbers of farmed escapees need to be significantly reduced to protect wild salmon populations from potentially damaging genetic introgression from domesticated salmon (Hindar et al., 1991, 2006; McGinnity et al., 2003; Skaala et al., 2006).”
Factors that contribute to the ecological risks of salmon and steelhead hatchery programs and some mitigating strategies (2009, background): “…hatchery smolts were 150–163 mm in length and weighed 27–36 g, while wild smolts were 122–129 mm in length and weighed 18–20 g. Larger size of hatchery juveniles has also been reported in other species (Mesa 1991; Gross 1998; Reinhardt et al. 2001; Weber and Fausch 2003; McGinnity et al. 2003).”
Economic, ecological and genetic impacts of marine stock enhancement and sea ranching: A systematic review (2018, background): “Another key study planted live Atlantic salmon eggs (wild, farmed and hybrids) in artificial redds in an experimental Irish river and found that lifetime RS (to wild) was only 2% for farmed fish, and the RS of the F1 hybrids was 27% (farmed female × wild male) and 42% (wild female × farmed male; McG”
Evidence of temporal genetic change in wild Atlantic salmon, Salmo salar L., populations affected by farm escapees (2006, background): “It was concluded that gene flow from farmed to wild salmon populations will reduce the productivity and fitness of wild salmon populations significantly (McGinnity et al., 1997; Fleming et al., 2000; McGinnity et al., 2003).”
Ecological and Evolutionary Consequences of Environmental Change and Management Actions for Migrating Fish (2019, background): “, 2012; Sunde and Forsman, 2016), thereby impairing population performance (Fleming et al., 2000; McGinnity et al., 2003).”
Conspecifics can be aliens too: A review of effects of restocking practices in vertebrates (2012, background): “High escape rates have been registered, reaching up to two million fish per year in the North Atlantic (McGinnity et al. 2003).”
Population structure in the Atlantic salmon: insights from 40 years of research into genetic protein variation (2005, background): “These issues are now being explored in more detail with DNA based analyses (McGinnity et al., 2003).”
Atlantic salmon in a rapidly changing environment—Facing the challenges of reduced marine survival and climate change (2021, background): “consequences of poorly planned or inappropriate stocking will reduce the ability of Atlantic salmon to adapt to environmental change (McGinnity et al., 2003).”
Differential lifetime success and performance of native and non-native Atlantic salmon examined under communal natural conditions (2004, methodology): “Although highly damaging and counter-productive (McGinnity et al., 2003) this procedure is still advocated from time to time in the angling press.”
