银鲑是在伊萨夸河及其东支流的陷阱中捕获的。大约一半的鱼的嗅坑被封闭，然后所有的鱼都被转移到两条河流交汇处以下约一英里的Issaquah。控制鲑鱼，不像那些闭塞的嗅觉坑，表现出很好的能力，重复他们原来的选择在流交界处。这被解释为意味着被操作的鱼不能区分两条溪流，而是以随机的方式分布。因此，如果鱼依靠嗅觉做出选择，那么结果与预期的结果是雅阁的。
Silver salmon were captured in traps in Issaquah Creek and its East Fork. The olfactory pits of approximately one-half of the fish were occluded before all of them were displaced to the Issaquah about one mile below the junction of the two streams. The control salmon, unlike those with occluded olfactory pits, showed an excellent ability to repeat their original choice at the stream juncture. This is interpreted to mean that the operated fish were not able to differentiate between the two streams but were distributing themselves in a random fashion. The results, therefore, are in accord with those which would be expected if the fish were relying on their sense of smell in making this choice.
