溪鳟鱼（Salvelinus fontinalis）吃26%的58个少年（7-11厘米）大西洋鲑鱼（萨尔莫salar）引入到人工流24小时前鳟鱼，但他们只吃了8%的60鲑鱼已经存在足够长的时间来建立领土。 人为的环境改变可能会减少年轻鲑鱼的领土行为，从而增加他们的脆弱性捕食。
Brook trout (Salvelinus fontinalis) ate 26% of 58 juvenile (7–11 cm) Atlantic salmon (Salmo salar) introduced into an artificial stream 24 h before the trout, but they ate only 8% of 60 salmon which had been present long enough to establish territories. Man-made environmental alterations may decrease territorial behavior of young salmon thereby increasing their vulnerability to predation.
