Hundreds of dead sharks and other fish have washed up on beaches in Wales.

Pauline Morris found a full net when she was out walking her whippet, Sonny, and whippet crosses, Saffy and Sammy, at Carmarthenshire's Pembrey Beach on Saturday.

Pauline, from Aberdare, in Rhondda Cynon Taf, said it was "horrible to see" and had put her off eating fish.

Last week, another walker came across a pile of dead marine life, believed to be catshark - also known as dogfish, at Saundersfoot, in Pembrokeshire.

Pauline, a 65-year-old nurse at Ysbyty Cwm Cynon, in Mountain Ash, described the washed-up fish as "a shocking thing to see, because of the size of it".

"It was over a quite big area - with fish and sharks held in a big net," she said.

"I don't know whether they came loose from a trawler or whether they were thrown [away] because it was not what they wanted."

Sea Trust Wales founder, Cliff Benson, believes many of the fish were catshark.

He said he had reported those found at Saundersfoot to Natural Resources Wales (NRW) after seeing an image posted on social media.

"It could have been from a trawler," he said.

NRW said the dead fish at Pembrey Beach had not been reported to them, but that the fish appeared to be discarded or part of a lost catch.

An officer had visited Saundersfoot beach, NRW said, but found no trace of the animals as they had been washed back into the sea.

A spokesperson said: "We investigated reports of dead fish at Saundersfoot and found no evidence of a pollution incident.

"The fish appear to be dogfish, and this is likely linked to fishing by-catch being discarded at sea.

"Tides have since cleared the majority from the shoreline and no wider environmental impacts were identified.

"We have informed the local authority and relevant partners."

Carmarthenshire council said it was aware of the incident and believed it was likely linked to a trawler operating offshore that may have discarded nets and bycatch.

"While it is always disappointing and concerning to see such incidents along our coastline, they are unfortunately difficult to trace back to a specific vessel or operator," said councillor Hazel Evans, deputy leader and cabinet member for Regeneration, Leisure, Culture & Tourism.

Pembrokeshire council has been approached for comment.
