Shark Populations: Why They’re Declining & Where to Find Them
- Angelshark populations in Wales, once thought to be dwindling rapidly, may be more stable than previously believed.
- The Zoological Society of London (ZSL) study suggests that shifts in fishing methods over the past half-century have significantly impacted the ability to monitor the angelshark.
- Researchers from ZSL and Natural Resources Wales partnered with the Welsh Fishermen’s Association and Angling Cymru to understand how fishing changes have affected angelshark encounters.
Discover why angelshark populations, critically endangered, in Wales may be more stable than previously believed. New research suggests that changes in fishing practices, not necessarily dwindling numbers, are the primary reason for fewer sightings of these masters of camouflage. The study, a collaborative effort between researchers, fishers, and organizations such as the Zoological Society of London, reveals how shifts in fishing methods may have impacted our ability to monitor these elusive creatures. Changes included modified fishing regulations and shifting target species within the marine environment. Environmental DNA (eDNA) analysis presents a new monitoring method, offering a fresh approach to determine the shark’s status.

Angelshark Numbers in Wales: Fishing Changes Cloud Sightings
Updated June 10, 2025
Angelshark populations in Wales, once thought to be dwindling rapidly, may be more stable than previously believed. A new study indicates that changes in fishing practices, rather than a drastic decline in numbers, could explain fewer sightings of the critically endangered angelshark. The angelshark, a rare and elusive species, is now primarily found in Welsh waters.
The Zoological Society of London (ZSL) study suggests that shifts in fishing methods over the past half-century have significantly impacted the ability to monitor the angelshark. These flat-bodied sharks, which can grow up to 8 feet long, are masters of camouflage, often burying themselves in the sand to ambush prey. Their preference for shallow, sandy coastal areas puts them at risk from destructive fishing practices.
Researchers from ZSL and Natural Resources Wales partnered with the Welsh Fishermen’s Association and Angling Cymru to understand how fishing changes have affected angelshark encounters. Interviews with 27 fishers revealed new fishing regulations, shifts in target species, and changing social attitudes have led to less time spent in angelshark habitats. This means fewer accidental catches, not necessarily fewer sharks.
“Identifying how changes to fishing practices over the last 51 years have impacted our ability to monitor them indicates that there may be more angelsharks swimming off the Welsh coast than we previously thought – we’re just having a harder time spotting them,”
To improve monitoring, scientists are turning to environmental DNA (eDNA). This technique involves analyzing water samples for traces of the shark’s genetic material. Jake Davies, Technical Specialist for Project SIARC at ZSL and NRW, noted that eDNA allows researchers to study the species without direct sightings, overcoming challenges posed by the angelshark’s camouflage.
Charlie Bartlett, a charter fisher from Gwynedd and co-author of the study, contributed his knowledge and experience from over 50 years working along the Welsh coast. He emphasized the importance of preserving Wales’ marine heritage and inspiring future generations.
“It’s been great to share personal experiences that help better understand angelsharks,”
The angelshark remains a highly threatened species. Projects like “Angel Shark Project: Wales” and Project SIARC aim to create a more accurate picture of their status and ensure their survival. The study highlights the need to rethink how angelshark populations are assessed, offering a glimmer of hope for the future of this unique species.
What’s next
Researchers plan to expand eDNA monitoring efforts and continue collaborating with local fishers to gain a more complete understanding of angelshark distribution and abundance in Welsh waters. This collaborative approach is essential for effective conservation strategies.
