Homing and straying by anadromous salmonids: a review of mechanisms and rates (2014, background): “…the anadromous populations must activate specific receptor cells to imprint on natal waters, prepare for saltwater entry, and recall the home stream odors as adults, the landlocked salmon did not appear to require these processes and hence these genes were not upregulated (Johnstone et al. 2011).”
Genetic and ecological effects of salmon farming on wild salmon: modelling from experimental results (2006, background): “In steelhead trout (Oncorhynchus mykiss), Chilcote (2003) found that in mixed populations of wild and hatchery fish, equal numbers of the two would produce 63% fewer recruits per spawner than one composed entirely of wild fish.”
Factors affecting marine production of Atlantic salmon (Salmo salar) (2004, background): “Also, in steelhead trout, the presence of hatchery fish appears to reduce the productivity of co-existing wild spawners (Chilcote 2003).”
Factors that contribute to the ecological risks of salmon and steelhead hatchery programs and some mitigating strategies (2009, background): “Chilcote (2003) surveyed 12 steelhead populations across the State of Oregon and found that when 50% or more of the adult fish on natural spawning grounds were hatchery fish, the productivity of wild fish declined by 63%.”
Genetic adaptation to captivity in species conservation programs (2008, background): “Characteristics selected for under-captive conditions are overwhelmingly disadvantageous in the natural environment (Leopold 1944; Bush 1978; Fraser 1981; Chilcote et al . 1986; Frankham et al . 1986; Allard 1988; Kohane & Parsons 1988; Lachance & Magnan 1990; Leider et al . 1990; Hindar et al . 199”
