Observed results in biological traits and life history strategies may be linked to the continued depression in overall population abundance due to hatchery practices. However, environmental stochasticity may also be influencing the population. Hatchery supplementation does not appear to be harmful in the short term and can minimize short-term extinction risks; however, long-term supplementation may have resulted in deleterious consequences in the Squamish River chinook population. A successful supplementation program will require integrating clear and measurable conservation goals and objectives, altering current hatchery mating and rearing practices, the promotion of a scientifically defensible approach, and the use of an adaptive management plan.Squamish chinook, therefore, are likely spending their adult life in the Strait of Georgia and other nearshore areas along ... in productivity (Beamish et al., 2007) ; however, artificial manipulations are confined by biological and logistical factors .
