title in English

Temporarily acoustic receiver network in the Upper Scheldt river, for river lamprey tracking in the Scheldt river basin

Acronym

2011_Bovenschelde

Description in English

The disruption of longitudinal and lateral connectivity of rivers has led to ecological catastrophes such as the extinction of several diadromous fish species. River lamprey is an important indicator species for the integrity of ecosystems and connectivity within and between catchment areas. In the highly fragmented River Scheldt basin first restoration actions are undertaken, such as the building of nature-like bypasses.

Abstract in English

In 2011 and 2012 forty-one adult river lamprey were followed during their upstream migration in the tidal and/or non-tidal part of the River Scheldt and its tributaries using acoustic telemetry (Vemco technology: V7 and V8 transmitters; VR2 and VR2W data loggers). The migration patterns in the river catchment and their behaviour at a tidal barrier, lock-weir complexes and fish bypasses (passage timing and delay) show that the disrupted water management of the river and in consequence of its barriers and bypasses are the key to (un)successful spawning migration in the catchment.
