Hundreds of dead sharks and fish wash up on two beaches in Wales

Local conservationist says a fishing boat hoping for a more commercial catch may have thrown them overboard

Hundreds of dead sharks and fish believed to be part of a discarded catch have washed up on two Welsh beaches.

Dogwalkers found a full net of dogfish, also known as catshark, on Carmarthenshire's Cefn Sidan on Saturday. The discovery came after hundreds more dead sharks and fish had been found on Saundersfoot beach in neighbouring Pembrokeshire a few days earlier.
