An Australian state government on Tuesday announced plans to mechanically pump oxygen into lakes and rivers after hundreds of thousands of fish have died in heatwave conditions. Up to a million dead fish were found floating last week in the Darling River in western New South Wales state and the state government announced that 1,800 more rotting fish had since been found in Lake Hume in the state’s south. Minister for Regional Water Niall Blair said 16 battery-powered aerators had been bought and would be placed in various drought-affected waterways after they are delivered by Wednesday.
