Presence of fish and crayfish in the eight streams at each sampling time, compared with historical presences.

Compiled from Raadik (1996) and Jackson and Davies (1983) as well as author's unpublished data from 2006–2007. Bold indicates species found upstream of weirs; underlined indicates rare or encountered infrequently (i.e. very patchily distributed, in one place in channel: not given for historical occurrences); # denotes almost all animals caught electrofishing the unregulated streams in 2007 were these species.本数据集汇编自Raadik（1996）、Jackson与Davies（1983）的研究成果，以及作者2006—2007年的未公开观测数据。文本中加粗字体代表在拦河坝上游发现的物种；下划线字体代表稀有或偶见物种（即分布极零散、呈斑块状分布，仅在河道单一位点出现，历史记录未对此类物种进行标注）；#符号表示2007年对无调控溪流开展电捕鱼采样时，捕获的个体几乎全部属于该类物种。
