Environmental DNA, Volume 7, Issue 5, September–October 2025.The Chinese mitten crab (Eriocheir sinensis) is considered amongst the most damaging invasive species globally; however, the UK distribution of the species is not well known, with current management protocols reliant on reports of individual sightings. In this study, the first probe‐based, species‐specific qPCR assay was developed for the detection of ...
