Over a dozen sharks unexpectedly found washed up along Welsh coastline

John Rees, who took the video, claimed to WalesOnline that it had taken place after a local fishing competition.

"I counted at least 15 dead dogfish and rays ," he said.

“Some had fishing tackle attached.

"Recreational fishing can have a significant impact on these types of sharks with many anglers using inappropriate fishing tackle or simply cutting lines rather than correctly unhooking.”

Bull huss are commonly found along the Welsh coastline all year.

They usually prefer deeper water and rockier ground so they can stay in cracks and crevices like at Knab Rock which is where Mr Rees took the video.

Welsh group 'Fishing' said bull huss could grow up to five feet in exceptional cases.

Most bull huss caught along Wales’ coast weigh between four pounds and 10 pounds.

While they're not regularly targeted, bull huss can be fished by anglers as a by-catch option.

As a result they have been listed near-threatened by International Union for Conservation of Nature (IUCN).

"Anglers need to be aware of the impact of their actions and ensure they are taking measures to minimise suffering," Mr Rees said.

Cameron Gigg celebrated catching a bull huss days later, off the pier of Porthcawl.

He said his picture was taken with the 11-pound shark before it was released back into the water.

"I think I'm the first person to catch one there," Mr Gigg said.

"I was very shocked when I caught one.

"It's my personal best."

Mr Gigg said he didn't feel "any fight on it".

"I didn't know I had it on the end of the line but it was massive. They're brilliant animals."

Mr Gigg said he knew someone who fished there "a lot" and he was told "he's never known anyone catch one down there".

"I know they are commonly caught down Knab Rock," he added.

Mr Gigg said he had seen posts on social media about the bull huss being killed and it was "awful to see".

"I've been going nuts about it. I've been broadcasting them on Facebook," he said.
