While the culture of Atlantic salmon currently dominates Canadian salmon aquaculture (94% of production), Pacific species such as Chinook salmon (Oncorhynchus tshawytscha) are increasingly attractive to producers due to their niche market price advantage, their higher disease and parasite resistance and their native species status in BC. However, despite these advantages, it is also possible that the native species may more readily feed upon familiar native prey, inadvertently impacting wild salmon stocks. Yellow Island Aquaculture Ltd. (YIAL) is a fully organic Chinook salmon hatchery and farm located on Quadra Island, BC. Started in 1985, YIAL remains the oldest, continuously-owned Pacific salmon farm in BC producing niche-market, high-quality specialty products. Since the 1990s, YIAL has been at the forefront of initiating integrative research in salmon production and conservation. One of the ongoing issues potentially limiting production capacity is the

虽然大西洋鲑鱼养殖目前在加拿大鲑鱼水产养殖中占主导地位（占总产量的 94%），但太平洋物种，例如奇努克鲑鱼 (Oncorhynchus tshawytscha)，由于其利基市场价格优势、较高的疾病和寄生虫抵抗力及其在 BC 省的本地物种地位，对生产者越来越有吸引力。然而，尽管有这些优势，本地物种也有可能更容易以熟悉的本地猎物为食，无意中影响野生鲑鱼种群。 Yellow Island Aquaculture Ltd. (YIAL) 是一家位于不列颠哥伦比亚省夸德拉岛的完全有机奇努克鲑鱼孵化场和养殖场。 YIAL 始建于 1985 年，至今仍是 BC 省历史最悠久、持续拥有的太平洋鲑鱼养殖场，生产利基市场的高品质特色产品。自 20 世纪 90 年代以来，YIAL 一直走在鲑鱼生产和保护综合研究的前沿。潜在限制产能的持续问题之一是
