Fish kill at Greenough River

The Department of Water and Environmental Regulation (DWER) is managing a fish kill in the lower section of the Greenough River after thousands of dead fish were observed in a 100 metre stretch along the north shore and adjacent to the boat ramp.

To help determine the cause of the kill DWER staff have collected water samples for analysis by their scientific staff and have sent fish samples to DPIRD for pathology testing. 

Fish kills can occur due to a wide range of factors, most often natural changes in salinity, acidity, temperature, oxygen levels and algal growth.  However, while the cause of this fish kill remains unclear, for your safety DO NOT collect or consume any fish in the vicinity of the kill, collect fish for bait or allow pets to come into contact with the fish.

For further information please see DWER’s media statement.

Please report fish kills to the 24 hour hotline FishWatch on 1800 815 507.

Further information
DWER manages fish kills in estuaries, rivers and naturally occurring inland water bodies, DPIRD is responsible for fish kills events that occur in ocean environments and the Department of Biodiversity, Conservation and Attractions manages fish kills in the Swan Canning Riverpark.
