Hundreds of dead stingrays found on Mexico beach 17 July 2013 Last updated at 11:16 Hundreds of dead stingrays have been found on a beach in the eastern Mexican state of Veracruz. The stingrays - more than 250 in total - were spotted on Chachalacas beach near the town of Ursulo Galvan on Tuesday. Some locals reported seeing fishermen dumping the rays on the beach. Veracruz's Environment Minister Victor Alvarado Martinez has asked federal authorities for help investigating the incident. Local mayor Jose Martin Verdero said it was "possible that the rays had got caught in nets" used by Chachalacas fishermen trying to catch other fish. But residents said they had been dumped after the fishermen did not get the price they wanted for them. Chachalacas fisherman Jaime Vazquez said that in his more than three decades in the job he had ever seen any of his colleagues dump dead fish on the beach. He told local media that any unwanted fish would have been returned to the sea while still alive.
