本文研究了日本北海道一条山间溪流中本地白点鲑鱼和非本地褐鲑鱼的纵向分布格局。褐鲑鱼占鲑鱼渔获量的比例从下游向上游递减。褐鲑鱼比例与水温呈负相关。因此，我们的结果表明，温度可能会影响本地白斑鲑鱼和非本地褐鲑鱼之间可能的竞争。
This study focused on longitudinal distribution patterns of native white-spotted charr and non-native brown trout in a mountainous stream in Hokkaido, Japan. Brown trout ratio, which is the proportion of brown trout in the catch of salmonids, was decreasing from downstream to upstream. Brown trout ratio correlated negatively with water temperature. Thus, our results suggested that temperature may influence the possible competition between native white-spotted charr and non-native brown trout.
