鲑鱼已被引入世界各地的非本土地区，通常没有考虑对本地物种的影响。这导致了许多非自然共生的物种组合，其中一些被怀疑存在强烈的相互作用，但我们目前没有足够的知识来预测大多数此类引入的结果。例如，尽管目前关于大西洋水域中饲养的太平洋鲑鱼的潜在影响存在争议，但我们只有经验证据来判断它们是否会对大西洋鲑鱼（Salmo salar）有害。此外，大多数其他溪流鲑鱼对之间种间竞争的实验测试并不严格。对溪流中溪流鳟鱼 (Salvelinus fontinalis) 和虹鳟鱼 (Salmo gairdneri) 之间疑似竞争的文献综述表明，尽管经验证据表明水温和流速在决定结果方面发挥着关键的相互作用作用，但...
Salmonids have been introduced worldwide to regions where they were not indigenous, usually without considering the effects on native species. This has led to many combinations of species in unnatural sympatry, some of which are suspected to interact strongly, but we currently have inadequate knowledge to allow us to predict the outcome of most such introductions. For example, despite current controversy about the potential effects of Pacific salmonids now stocked in Atlantic waters, we have only empirical evidence with which to judge whether they will be detrimental to Atlantic salmon (Salmo salar). Moreover, most experimental tests of interspecific competition between other pairs of stream salmonids have not been rigorous. A review of literature about the suspected competition between brook trout (Salvelinus fontinalis) and rainbow trout (Salmo gairdneri) in streams reveals that despite empirical evidence that water temperature and velocity play a critical interacting role in determining the outcome, mo...
