Capture fisheries alone are unable to sustain demand for seafood, and aquaculture is a growing source for that demand. Salmon farming is one of Canada's growing industries and is extremely valuable ($1,000 million in 2010; Stats Canada). However, salmon farming must balance production economics with environmental impacts. Farmed Chinook salmon are a valuable niche market with substantial growth potential, coupled with lower perceived environmental concerns (being a native species); however, their performance has not been systematically assessed. We will develop a performance-enhanced hybrid Chinook salmon stock with higher survival and growth and reduced feed costs. The new stock will use less wild-sourced lipid and protein for feed and minimize drug & chemical use for disease control, thereby minimizing the environmental footprint. The project will generate data on Chinook salmon production stocks that will serve to improve salmon farming efficiency which will help make Canada a global leader in Pacific salmon farming.

仅靠捕捞渔业无法维持对海鲜的需求，而水产养殖是这一需求的一个日益增长的来源。三文鱼养殖是加拿大不断发展的产业之一，价值极高（2010 年为 10 亿加元；加拿大统计局）。然而，鲑鱼养殖必须平衡生产经济效益和环境影响。养殖奇努克鲑鱼是一个有价值的利基市场，具有巨大的增长潜力，而且人们对环境的担忧较低（作为本地物种）；然而，他们的表现尚未得到系统评估。我们将开发性能增强的杂交奇努克鲑鱼种群，具有更高的存活率和生长速度，并降低饲料成本。新种群将减少使用野生来源的脂质和蛋白质作为饲料，并最大限度地减少用于疾病控制的药物和化学品的使用，从而最大限度地减少环境足迹。该项目将生成有关奇努克鲑鱼产量的数据，这将有助于提高鲑鱼养殖效率，从而帮助加拿大成为太平洋鲑鱼养殖的全球领导者。
