尽管一些研究表明孵化场和野生溯河产卵太平洋鲑鱼（Oncorhynchus spp.）之间存在遗传差异，没有人提供令人信服的证据证明人工繁殖对自然产卵种群的保护构成遗传威胁。当发表的研究和正在进行的三项研究被认为是集体，但是，他们提供了强有力的证据表明，适合自然产卵和饲养可以迅速和大幅减少人工繁殖。这个问题在太平洋西北部非常重要，在那里用孵化场鱼类补充野生鲑鱼种群已被确定为恢复这些种群的重要工具。认识到负面影响可能会导致限制补充剂的使用，以及更好的保护，更好的评估，以及使用补充剂时的更大益处。? 1999年国际海洋考察理事会
Although several studies have shown genetic diVerences between hatchery and wild anadromous Pacific salmon (Oncorhynchus spp.), none has provided compelling evidence that artificial propagation poses a genetic threat to conservation of naturally spawning populations. When the published studies and three studies in progress are considered collectively, however, they provide strong evidence that the fitness for natural spawning and rearing can be rapidly and substantially reduced by artificial propagation. This issue takes on great importance in the Pacific Northwest where supplementation of wild salmon populations with hatchery fish has been identified as an important tool for restoring these populations. Recognition of negative aspects may lead to restricted use of supplementation, and better conservation, better evaluation, and greater benefits when supplementation is used. ? 1999 International Council for the Exploration of the Sea
