Despite the ecological and societal importance of large rivers, fish sampling remains costly
and limited to specific habitats (eg, river banks). Using an eDNA metabarcoding approach …

Environmental DNA (eDNA) metabarcoding is an effective method for studying fish
communities but allows only an estimation of relative species abundance (density/biomass) …

Most of the present EU Water Framework Directive (WFD) compliant fish‐based assessment
methods of European rivers are multi‐metric indices computed from traditional electrofishing …

Large rivers and their estuaries are structurally complex and comprise a diversity of habitats
supporting a rich biodiversity. As a result, identifying and monitoring fish communities using …

As fish communities are a major concern in rivers ecosystems, we investigated if their
environmental (e) DNA signals vary according to the sampling period or hydromorphological …

Monitoring freshwater fish communities in a large human‐impacted river is a challenging
task. The structure of fish assemblages has been monitored yearly in the Marne and the …

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 …

Fish species richness is an important indicator of river ecological condition but it is
particularly difficult to estimate in large unwadeable rapidly flowing rivers. Intensive multi …

Aim To analyse the occurrence and abundance of native versus alien fish species in relation
to climate, land use, hydrologic alteration and habitat fragmentation in a heavily invaded and …

A river is an ecosystem where fish fauna represents an important structural element. To re-
establish connectivity, it is imperative to allow movement between functional habitats. Due to …
