SYDNEY (Reuters) - Low levels of oxygen in Australia's second longest river were to blame for a mass fish die-off recently in a remote part of New South Wales state, environmental authorities said.
Thousands of dead fish have been found this week in the Darling River near the town of Menindee, around 1,000km (620 miles) west of the state capital Sydney.
