Stretches of the Murray River could become an “ecological desert” because widespread flooding has reduced water quality, a scientist has warned, as New South Wales communities rally to save fish populations.
Dr Ian Wright, a professor at Western Sydney University’s School of Science, believes fish and other aquatic wildlife are dying in huge numbers along the river as dissolved oxygen levels plummet – and the ecological impact could be “catastrophic”.
