On Monday, Scores of dead fished surfaced in drought-hit Australia’s Darling River. New South Wales Water Minister Niall Blair declared it an “environmental disaster”. This is the third incident of fish fishery mortality in the last two months.
Weather conditions, low water, and oxygen levels, and potentially poisonous pods have been suspected to cause death, said Sydney Morning Herald.
“Further fish deaths in the Darling River are anticipated as a significant number of fish have been observed under stress,” the department said in a statement.
Darling River is part of the Murray-Darling River system that spreads thousands of kilometers in many states.
There is no possibility of temperature rise and there is no chance of rainfall, there remains one “high risk of further fish kills over the coming days and week,” officials said.
The federal government has executed the death on severe drought, experts and locals say that they stop the river systematic decline and pollution.
The inspectors added that the latest bout of kills was likely linked to “low level of decomposed oxygen” due to the rapid decrease in temperature after the likely hot weather.
New South Wales Regional Water Minister Niall Blair visited Menindee on Tuesday. National Broadcaster ABC has established only “band-aided solution” to the airwaves in the rivers because they have no government option.
“It’s not a case of not being able to spend money on something, there just isn’t any other alternative that anyone has offered up,” Blair said.
“The only thing that will really change these conditions at the moment is fresh water coming through the system and there is just no possibility of that at the moment.”
