According to the test and observation indicated that mostly fish goes upstream and far away the sluiceway when fish migration , so fishway designed by us was arranged in the right bank of reservoir area and far away from the electricity generation hole intake upstream about 280 meters in order to induce the fish entering the fishway 根據試驗和觀察表明,魚類洄游時大都沿岸上溯,同時應遠離泄水道,故我們的魚道進出口是布置在庫區右岸,離發電洞進口上游約280米處,以利誘導魚類進入魚道。

Having carried on the direction and in - situ observation research for the fish migratory behavior , swimming mechanics and ecology , etc ; using the light , sound , electricity , colour gas and various physical agents to improve the fish passage speed in the fishway 對魚類的洄游習性、游泳力學及生態學等問題,進行了定向和原體觀測研究,并用光、聲、電、色、氣等各種物理因素提高魚道的過魚效果。

The route choice for fishway should follow the earlier principle and combine the actual situation of the project and decided by reconnaissance and measure of reconnaissance investor , design and constructing unit together 魚道線路選擇遵循前面的原則,結合本電站的實際情況,由投資方、設計和施工單位共同進行勘察、測量而定。

In order to make the fishway design more reasonable and make the fish migration and semi - migration passing the fishway successfully , each country attaches great importance to research of fishway design 為了使魚道設計更合理,使洄游、半洄游魚類能順利通過魚道,各個國家都很重視魚道設計的研究。

1 choice of fishway intake is the key of success or failure 魚道進出口的選擇:這是魚道設計成敗的關鍵。
