A New Hope for the Angelshark

In an exciting twist for conservation enthusiasts, recent research suggests that the decline of angelsharks along the Welsh coastline may not be as devastating as previously believed.

Experts from the Zoological Society of London (ZSL), Natural Resources Wales (NRW), and local fishing organizations have revealed surprising insights in their new study published in People & Nature.

What the Data Really Shows

Earlier estimates claimed that angelshark populations had plummeted by 70% since the 1960s, largely based on the observation that fishers were encountering them less frequently. However, researchers are now suggesting that this apparent decline could be attributed to changes in fishing practices rather than a true decrease in numbers.

Francesca Mason, the lead author and a researcher at ZSL's Ocean Predator Lab, stated, "Changes in fishing practices over the last five decades suggest that there may actually be more angelsharks swimming off the Welsh coast than we thought. We’re simply having a harder time spotting them." This revelation means fewer accidental catches, but it also highlights the urgent need for improved monitoring techniques.

Angelsharks: Nature's Masters of Camouflage

Often described as flat, diamond-shaped predators, these critically endangered sharks are adept at blending into their sandy habitats. Their light-brown speckled skin allows them to ambush prey by lying buried beneath the sand.

Innovative Techniques for Tracking

Due to their elusive nature, scientists traditionally relied on incidental catch reports from fishermen. Yet, a groundbreaking method is on the rise—environmental DNA (eDNA) analysis. This innovative technique involves collecting water samples to identify traces of genetic material from various marine species.

Jake Davies, a technical specialist for Project SIARC at ZSL and NRW, explains, "With their excellent camouflage, one of the hardest challenges we face studying angelsharks is simply finding them. eDNA allows us to study species without having to spot them directly." By testing the waters in Cardigan and Carmarthen Bays, researchers have confirmed the presence of a plethora of marine life, including angelsharks.

Together for Conservation

The collaboration with local fishermen, such as charter fisherman Charlie Bartlett, plays a crucial role in this research. Bartlett, who shares his angelshark sightings with the Angel Shark Project: Wales, emphasizes the importance of combining local knowledge with scientific expertise.

Mason adds, "This work showcases the effectiveness of conservation efforts when we unite diverse expertise—from those living alongside these creatures to cutting-edge research and science."

What’s Next?

As the fight to protect angersharks continues, this new understanding offers a glimmer of hope for the species and our marine ecosystems at large. Together, we can inspire future generations to cherish and protect our rich marine legacy.
