The effect of ramp slope and substrate grain size on the passage of juvenile American Eel
(Anguilla rostrata) over indoor ramps was tested from May–August 2016. Two size classes of …

Instream structures such as dams, weirs and culverts reduce diadromous fish (eg freshwater
eels) biodiversity and abundance by restricting upstream migrations. Fish passes are used …

Conservation programmes for endangered, long‐lived and migratory species often have to
target multiple life stages. The bottlenecks associated with the survival of juvenile anguillid …

Abstract The European eel (Anguilla anguilla) is a fascinating species, exhibiting a complex
life cycle. The species is, however, listed as critically endangered on the IUCN Red List due …

Understanding how the physical habitat influences growth and behaviour is essential for
developing effective habitat restoration programmes of threatened and endangered fish …

Dams and other man‐made barriers impair upstream fish migration and thus threaten fish
populations that need access to upper river reaches to complete their life cycle. For many …

New lamprey-friendly fishways feature inclined ramps that facilitate passage of Pacific
lampreys (Lampetra tridentata (Richardson, 1836)) over Bonneville Dam on the Columbia …

The waterways of the North American Great Plains have experienced extensive
fragmentation from instream structures and intermittency caused by excessive dewatering …

The European eel is critically endangered due to heavy impact of anthropogenic factors,
such as habitat fragmentation, overexploitation and climate change. During downstream …

Installation of baffles intended to improve fish passage through culverts can reduce
discharge capacity and trap debris, increasing flood risk. A sloping upstream face may …
