Shark more common than thought around Welsh coast

AN ENIGMATIC species of shark known to favour Welsh waters could be more abundant than previously suspected, scientists believe.

The angel shark, a large flat species resembling a stingray, has evolved very differently from other types of shark.

While previously the Canary Islands were the place for reliable sightings, catch evidence from Welsh fishermen has shown that Cardigan Bay is also a stronghold for this elusive and vulnerable species.

The Welsh population was thought to be shrinking dramatically as a result of habitat damage and by catch fishing, with one study indicating a 70% decline since 1970.

A major conservation project was launched in the hope of saving a species that lingers on the sea floor, half-buried in sand and mud, waiting for prey to swim near them. They can grow up to 2.4m (8ft) long.

However, a new study, People & Nature, from the Zoological Society of London (ZSL) and Natural Resources Wales (NRW) suggests previous angel shark counts were wide of the mark.

Its authors believe changes to commercial fishing practices have seen fewer angel sharks caught.

As the speckled, caramel-coloured sharks are masters of camouflage, finding them on the sea floor is virtually impossible.

Instead, evidence from boat captains is the only reliable way the population can be assessed.
