Breakthrough eDNA Membrane Developed by UCL and Bangor University Researchers to Revolutionize Inshore Fish Monitoring

A team of scientists from University College London (UCL) and Bangor University has unveiled a groundbreaking environmental DNA (eDNA) membrane capable of capturing fish genetic material in coastal waters with unprecedented efficiency. The new membrane, engineered to filter trace DNA from skin cells, mucus, and excrement shed by marine life, enables real-time, non-invasive monitoring of inshore fish diversity—critical for assessing ecosystem health and guiding sustainable fisheries management. Field trials conducted in UK coastal zones demonstrated a 40% increase in detection accuracy compared to traditional sampling methods. The innovation addresses long-standing challenges in marine biodiversity tracking, where conventional techniques like trawling are invasive, costly, and often miss rare or elusive species. By deploying these membranes in strategic locations along the English Channel and Irish Sea, researchers have successfully identified over 85 fish species—including endangered ones like Atlantic cod and European eel—within weeks of deployment. This rapid, scalable solution offers governments and conservation groups a powerful tool to meet international biodiversity targets under the UN’s Global Biodiversity Framework. With climate change accelerating shifts in marine habitats, the ability to monitor fish populations in near-real time is more vital than ever. The UCL-Bangor collaboration now aims to commercialize the technology through partnerships with marine research institutes and environmental agencies across Europe and North America. As global demand for sustainable ocean stewardship grows, this eDNA breakthrough could become a cornerstone of next-generation marine surveillance.
