Juvenile coho salmon were exposed to morpholine or phenethyl alcohol (p-alcohol) for 1 1/2 months and then released in Lake Michigan. During the spawning migration 18 months later, morpholine and p-alcohol were metered into separate streams, and the number of morpholine- and p-alcohol-exposed fish returning to each stream was determined. Seventeen other locations were also monitored. The majority of the fish exposed to morpholine were captured in the stream scented with morpholine and most fish exposed to p-alcohol were captured at the p-alcohol-treated stream. This field study demonstrates that coho salmon imprint to and utilize chemical cues for homing.
将幼年银大麻哈鱼暴露于吗啉或苯乙醇（对乙醇）中1个半月，然后放生于密歇根湖。在18个月后的产卵洄游期间，将吗啉和对乙醇分别计量加入不同的溪流中，并确定回到每条溪流的接触过吗啉和对乙醇的鱼的数量。还对其他17个地点进行了监测。大多数接触过吗啉的鱼在散发着吗啉气味的溪流中被捕获，而大多数接触过对乙醇的鱼在经过对乙醇处理的溪流中被捕获。这项实地研究表明，银大麻哈鱼会记住并利用化学信号来进行洄游。
