TL;DR: In this paper, 17 experts from different fish passage research fields (i.e., biology, ecology, physiology, ecohydraulics, engineering) and from different continents (e.g., North and South America, Europe, Africa, Australia) identified knowledge gaps and provided a roadmap for research priorities and technical developments.

TL;DR: The first concerted efforts to develop scientifically-based fishways for upstream migrating fish began in the early 1900s in Europe with field and laboratory testing of different fishway designs as discussed by the authors.

TL;DR: In this article, the development of effective fishways requires biological knowledge of fish behaviour when encountering variable flows, velocity and turbulence, combined with hydraulic and civil engineering knowledge and expertise to develop facilities that provide appropriate hydraulic conditions that fish will exploit.

TL;DR: Fishways have traditionally been designed to provide safe passage for jumping fish and only recently have non-jumping species been considered Concern over dwindling populations of lake sturgeon.

TL;DR: In this article, the authors performed a laboratory study on the flow and erosion around simple habitat structures and found that the Froude number of the approaching flow was in the range of 0.074 to 0.6.
