Fish suddenly became ill with cancer

07.08.2012


Michael Sweet and his colleagues at the University of Newcastle found in the waters of the Pacific Ocean, on the Great Barrier Reef in Australia, trout with dark spots on the skin.


Sweet and other researchers have ruled out fungal disease as a cause of injury and are confident that the black scars that are very similar to the manifestations of melanoma in humans, are in fact symptoms of skin cancer.

Local fishermen call a trout Rambo because of scarred and blackened fish skin looks as if it had survived the war.

According to scientists, this is the first known case of detection of skin cancer in wild marine fish populations.

Coral trout found in the coral reefs. The fish lives in clear waters, but their habitat is under the ozone hole. So after exclusion of scientists factors such as pathogens and pollution of the marine environment, the most likely cause of the cancer is just a weakened ozone layer, which increases the flow of solar radiation on Earth and explains the high prevalence of the disease: 15 percent of fish samples in the area had cancerous lesions .
