'Massive, catastrophic' Murray fish kill sparks big questions

Description

A respected University of Western Australia expert has urged the public and the government to "ask harder questions" in the wake of a "catastrophic" fish kill that left 30,000 fish floating on the Murray.

The dead fish include bream, whiting, flounder, crabs and mulloway around the South Yunderup area, and downstream of Forrest Highway towards the river mouth. An investigation into the "event" was launched with fish and water samples collected for testing.
