Abstract：
Electrofishing and visual observations revealed contrasting riverine distribution and habitat use of the Japanese eel, Anguilla japonica, and the giant mottled eel, Anguilla marmorata, in a relatively gentle-slope river of Southern Kyushu, Japan. A. japonica was distributed in the lower and upper reaches. A. marmorata inhabited the middle reaches with relatively fast water velocity, heterogeneous water depth, coarse substrata and no adjacent paddy fields. This may have important conservation implications because a decrease in environmental diversity and/or river connectivity could result in the disappearance of A. marmorata habitats.
摘要：
电捕捞和视觉观察显示，日本鳗鱼的河流分布和栖息地使用形成对比，安圭拉,和巨大的斑驳鳗鱼，安圭拉马莫拉塔,在九州南部相对缓坡的河流中，日本。粳稻分布在下游和上游。A.marmorata居住在中游，水流速度相对较快，非均质水深,底层粗糙，没有相邻的稻田。这可能具有重要的保护意义，因为环境多样性和/或河流连通性的减少可能导致A.marmorata栖息地的消失。
