As many as a million fish are believed to have died along the banks of a major river system in drought-battered eastern Australia, and the authorities warned Monday of more deaths to come.
The banks of the Murray-Darling Rivers are thick with rotten fish, with officials putting the number of dead at hundreds of thousands and saying the toll is likely closer to one million.
Further high temperatures forecast for this week could make the situation worse, the New South Wales government has warned.
Low water conditions and the heat may also have encouraged an algae bloom that starves the fish of oxygen and produce toxins.
“We do expect to see more fish kills across parts of the far west and Northern Tablelands this week,” said state minister Niall Blair.
The deaths have become a national issue, sparking angry allegations about the cause and who is responsible.
“It’s a devastating ecological event,” said Prime Minister Scott Morrison on Monday, pointing to apocalyptic scenes.
Morrison’s government has blamed the fish deaths on drought and defended policies which some locals say has caused the systemic depletion and pollution of the river system.
“There’s a drought and this is one of the consequences of drought. There are many, and my focus on drought has not shifted one inch,” Morrison said.
But for years’ scientists have been warning of people extracting vast amounts of water without check for irrigation or other uses, undercutting billions of dollars of investment.
