Water Users At West Lakes To Remain Vigilant::

Waters users at West Lakes can still enjoy recreational fishing and boating, however should remain vigilant following yesterday’s discovery of a fish kill.

On Thursday 11 January, Primary Industries & Regions SA (PIRSA) Fisheries and Aquaculture was alerted to a fish kill of approximately two to three hundred fish including Bream, Snapper, Mulloway, Trevally, Mullet and Crabs at West Lakes, near the Trimmer Parade inlet.

Fish were inspected and determined to have died more than 6-12 hours before and were too decomposed for further testing. Water samples were collected from the scene for investigation and testing. The cause was determined to be a combination of low oxygen (recorded at less than 30%), high temperature, dodge tides and potential algal blooms during the previous week.

Fish kills of this nature are not uncommon in SA waterways, including estuaries, embayment’s and man-made waterways. No harmful or toxic algae has been detected in the water samples collected on 11 January 2018.

Dead or dying fish found during any fish kill event are not recommended for human consumption. SA Health have advised that there are no restrictions on water based activities in West Lakes.

Fish kills should be reported to the FISHWATCH 24 hour hotline 1800 065 522.

Water users and visitors to the West Lakes area can still enjoy recreational fishing and boating on the water; however any dead or dying fish should not be taken for consumption.

While some people may be concerned when seeing dead or distressed fish, it is important to remember that this is not uncommon during the summer periods.
