Millions of dead fish wash up amid heat wave in Australia

Millions of fish have washed up dead in southeastern Australia in what authorities and scientists say is caused by floods and hot weather. The Department of Primary Industries in New South Wales state say the fish deaths coincided with a heat wave that put stress on a system that has experienced extreme conditions from wide-scale flooding. The deaths were likely caused by low oxygen levels as floods recede, a situation made worse by fish needing more oxygen because of the warmer weather. Residents of the Outback town of Menindee complained of a terrible smell from the dead fish as they started to clean up. Fish kills on the river have occurred before during severe drought conditions.
