The acquisition of information on fish stress has been recognized as an urgent need for
monitoring water quality, preventing disease, and improving welfare. Minimizing the …

Geolocating aquatic animals with acoustic tags has been ongoing for decades, relying on
the detection of acoustic signals at multiple receivers with known positions to calculate a 2D …

Hydropower plants commonly impede the downstream migration of Atlantic salmon (Salmo
salar) kelts. Thus, understanding the effects of hydraulic conditions on kelt behaviour and …

Biomonitoring of complex heterogeneous environments is highly challenging. Fish in deep
water bodies occupy different habitats, so a combination of survey methods has traditionally …

Acoustic telemetry (AT) has emerged as a valuable tool for monitoring aquatic animals in
both European inland and marine waters over the past two decades. The European …

The global population of European eel (Anguilla anguilla) is rapidly declining, and migration
barriers in rivers are believed to be one of several key causes. While progress has been …

Recent acoustic telemetry positioning systems are able to reconstruct the positions and
trajectories of organisms at a scale of a few centimeters to a few meters. However, they …

American eel (Anguilla rostrata) often pass hydropower dams during adult spawning
migrations. We conducted a 4-year acoustic telemetry study that characterized passage risks …

Each year, thousands of fishes are tagged with electronic devices to study their biology and
inform fisheries management. Such research assumes that the process of capturing …

Fine-scale tracking technology has advanced our understanding of aquatic animal
behaviour by deriving near-continuous movements of animals ranging in size from small …
