The bleak Alburnus alburnus is a medium body-size leuciscid fish that is naturally distributed
across central European and western Asian fresh waters. However, during the last two …

Most lotic ecosystems have been heavily modified in recent centuries to serve human
needs, for example, by building dams to form reservoirs. However, reservoirs have major …

The restoration of migration pathways for fish is crucial for the maintenance of populations in
a worldwide context of increasing river fragmentation due to the development of dams …

Migration patterns and habitat use of adult barbel (Barbus barbus) and nase (Chondrostoma
nasus) were monitored by radio telemetry over a period of 13 months along a 58-km-long …

A more holistic approach towards testing longitudinal connectivity restoration is needed in
order to establish that intended ecological functions of such restoration are achieved. We …

River connectivity is essential for the resilience of fish assemblages and populations and is
a priority goal to reach good ecological status for river systems. Increasing knowledge on the …

Hydropower use of watercourses has tangible consequences for the environment, society
and economy. Based on a literature review and their own research, the authors present …

Human activity has caused longitudinal fragmentation of many rivers. Fishways have been
installed worldwide, but their successive use by potamodromous species remains poorly …

Fishways are used worldwide to restore fish migration routes. However, there are few
standardized metrics that allow the comparison of their performance in a consistence …

Fishways are installed worldwide to facilitate accessibility to functional habitats and to
increase the ecological continuity of rivers. Their evaluations are increasing, but complete …
