Passive Water Filtration Enhances the Detection of Endangered Fish Species in Rivers: Anguilla anguilla and Salmo salar Monitoring Using qPCR

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study assesses the effectiveness of environmental DNA (eDNA) for monitoring the critically endangered Anguilla anguilla and the near‐threatened Salmo salar using quantitative PCR. Active in situ water filtration and passive metaprobe deployment were compared, showing that metaprobes provided greater sensitivity for low‐abundance species, while ...
