2018年5月1日 · Fishways play an increasingly important role in restoring free passages in rivers for aquatic organisms, especially fishes. Effective fishway operations are the prerequisite for the restoration of fragmented habitats. Research has shown that most existing fishways in China are not functioning correctly.

魚道 （英語： Fish way）或稱為 魚梯 （Fish ladder），是為了幫助 洄游 性魚類能在人工的水利環境或天然屏障（例如 堤壩 、 船閘 、 瀑布 等）中生存的設施。 多數魚道的設計是利用較平緩低矮的階梯狀水道 (魚梯)，使魚類能夠逆流而上，穿越如水壩等因為落差而造成的障礙。 魚道中的水流必須快到能夠吸引魚隻溯溪，卻又不會耗盡魚的體力以免牠無法繼續餘下的旅程 [1]。 早於17世紀的 法國 文獻中已有記載，人們利用綑束起來的樹枝，在陡陗的河道上製作階梯狀的魚道， …

A fish ladder, also known as a fishway, fish pass, fish steps, or fish cannon, is a structure on or around artificial and natural barriers (such as dams, locks and waterfalls) to facilitate diadromous fishes' natural migration as well as movements of potamodromous species. [1]

A fishway or fish ladder is a waterway constructed on or around a natural or artificial obstruction to provide a passageway for fish and other aquatic species. The construction of fishway allows a seamless migration for the aquatic ...

A fishway is a waterway designed to allow the passage of a species or a number of different species of fish past a particular obstruction. While in most cases fishways are built for adult spawners in some cases migrating juveniles are the target species.

2024年2月29日 · Stepped fishways are the main alternative to allow fish migration in river obstacles. Their design is a multidisciplinary process, where civil engineering meets biology. This can bias the fishway design towards one discipline, which may cause low efficiencies or inadequate solutions.

2014年9月1日 · A fishway, also known as a fish passage, fish-pass or fish ladder, is a type of structure that provides a route for migrating fish to travel across artificial barriers (e.g., dams, weir locks, or road crossings) or natural barriers (Water Resources Institute, now changed to “Hohai University”, 1982; Baumann and Stevanella, 2012). The ...

Fishway has been an effective way used to restore fish migration passages, and bridge fragmented habitats. The purpose of a fishway is to assist fish in smoothly bypassing an obstacle and alleviate the negative effects of the hydraulic structure.

A fishway can be defined as any artificial flow passage that fish negotiate by swimming or leaping (i.e., fish ladders) (243). In an engineer-ing context, it is a waterway specifically designed to afford fish passage around a particu-lar obstruction (121). It may be any structure, or modification to a natural or artificial structure,

2017年12月14日 · The results were analyzed considering the four stages that a fish must overcome in a fishway (attraction, entry, passage and exit), the fishway type and the construction period.
