Hundreds of thousands of fish were found dead in the Darling River in southeastern Australia in the third environmental disaster of its kind in two months, official sources said Tuesday.

New South Wales Regional Water Minister Niall Blair confirmed the new case after photographs of dead fish, which were published by Menindee residents, emerged on Monday.

This town, located some 930 kilometers west of Sydney, the state capital, is the center of this ecological catastrophe which affects the country's main river system, amidst a severe drought and intense heat.

Blair said the state government no longer has any other solutions in mind after installing aerator devices to inject air into the river to try to keep the fish alive.

This mortality is beyond the control of the government and "if there was something else that could be done we would have done it," the minister told national broadcaster ABC.

About a million fish have died near Menindee due to the presence of oxygen-absorbing algae, conditions that have been aggravated by drought and abrupt temperature changes.

However, several sectors of the affected areas claim that the poor management of the water resources in this valuable agricultural area along the Murray and Darling river basins contributed.
