本研究在大甲溪畔八寶圳取水口附近建立三座試驗性質的階段式魚道，其特點在於利用八寶圳的天然溪水以重力方式進行試驗魚道的引水及排水，以木質材料建構而成，易於改變魚道型式、坡度與流量等控制因子。以台灣原生魚種之台灣石(魚賓)與台灣鏟頜魚進行各項魚道試驗，包括魚類跳躍高度試驗、魚道溯游試驗及三座下池連通魚道試驗等魚類行為試驗。

Using wood as the construction material and ambient water from the Pabaw irrigation canal as experimental water under gravity flow, three experimental fish ways were established along the shore of the Daika River in Taichung. They were designed so that types, slopes and baffle heights of the fishways, as well as flow rates of the experimental water were easily changeable. In the experiment, two types of fishway baffles with three slopes were tested, using two native species of fishes in Taiwan, Acrossocheilus formosanus and Varicorhinus barbatuJus, as experimental fishes. This paper describes the designs of the fishways and the results obtained in the preliminary experiment.
