Report reveals findings of Cockburn Sound fish kill investigation

The Cockburn Sound fish kill incident report, revealing the findings of the cause of fish deaths in November 2015, is now available.

A bloom of microscopic Chaetoceros algal species was identified as the likely cause.

The report states that potential contributing factors for the bloom include nutrients, higher than normal water temperatures and reduced flushing conditions.

We will continue to monitor the levels of algae in the southern part of Cockburn Sound. We will also continue to monitor the Sound, in particular for crabs and snapper eggs and larvae, to help determine the impact of the fish kill.

A planned multi-agency meeting is expected to lead to improved responses and management of any future fish kill events in the area.
