Genetic architecture of growth and early life-history transitions in anadromous and derived freshwater populations of steelhead (2004, background): “High lipid levels, which might be more common in a hatchery environment, however, may have stimulated high rates of early male maturity (Shearer & Swanson, 2000; Larsen et al., 2004) and subsequently reduced smolting rates.”
Characterizing the distribution of an endangered salmonid using environmental DNA analysis (2015, background): “However, summer Chinook juveniles that fail to migrate to the ocean, potentially up to about 40% of males in a hatchery population (Larsen et al., 2004; Larsen et al., 2013), could also contribute to detectable Chinook eDNA during the June sampling event, particularly at sites lower in the basin.”
Comparison of Life History Traits between First-Generation Hatchery and Wild Upper Yakima River Spring Chinook Salmon (2006, background): “Larsen et al. (2004) estimated that the CESRF hatchery produced significantly more age-2 precocious males than the naturally spawning wild population, which produced both age-1 and age-2 precocious males (Pearsons et al.”
Mating success of alternative male phenotypes and evidence for frequency-dependent selection in Chinook salmon, Oncorhynchus tshawytscha (2010, background): “2002), similar growth and body size triggers for early male maturation (Larsen et al. 2004; Shearer et al. 2006), and the evidence of FDS provided in the present study suggest that alternative male phenotypes in Chinook salmon may be most accurately modeled in a manner similar to that for Atlantic s”
Effects of growth rate/body size and a low lipid diet on the incidence of early sexual maturation in juvenile male spring Chinook salmon (Oncorhynchus tshawytscha) (2006, background): “Early sexual maturation of male salmon results in reduced effectiveness of enhancement efforts (Larsen et al., 2004) and a financial loss to the salmon farming industry.”
