Thousands of tilapia fish carcasses have found been floating in a lagoon in Torres, south-east Brazil.<br /><br />Filmed on July 16, the footage shows vast amounts of dead fish being washed to the banks that line the lagoon.<br /><br />The filmer told Newsflare: "Every winter, many tilapia fish die from the cold; it is a natural phenomenon.<br /><br />"The days were a bit warmer when everybody woke up to this… hundreds of dead fish and not only tilapia, and there was even dead terrapin! <br /><br />"People kept removing them from the water, and countless bags were filled, and even a tractor had to be used to remove the dead animals, due to the absurd amount. <br /><br />"No matter how many big garbage bags had already been filled with fish, more and more hundreds just kept turning up dead.<br /><br />"Since the fish stopped dying after three days, the people stopped asking questions and the issue was put to rest, even though the water was apparently never analyzed."
