Fish deaths, shellfish advisory

Gippsland Lakes fish deaths incident, 17 Feb 2016.

Environment Protection Authority Victoria (EPA) has received a report of about 20 dead black bream and one estuary perch near Seacombe boat ramp in McLennans Straight in the Gippsland Lakes. Fish are being collected for analysis with water sampling also scheduled to take place.

Initial indications are that the cause is likely to be the decomposition of a red algal bloom occuring in the lake system, which reduces dissolved oxygen levels. The fish deaths are not a result of the current Pseudo-nitzschia algal bloom affecting parts of the Gippsland Lakes. Test results from this incident are due by the end of the week.

EPA is working with the Department of Health and Human Services and the Department of Environment, Land, Water and Planning to examine the fish deaths and to identify the cause.

Gippsland Lakes Pseudo-nitzchia algal bloom advisory cancelled

The Department of Health and Human Services (DHHS) has cancelled the precautionary advice issued on 7 February not to eat mussels, oysters and pipis collected from the Gippsland Lakes due to an algal bloom. DHHS Acting Chief Health Officer, Dr Roscoe Taylor said: “The results from testing of seafood have shown toxin levels well below food safety guideline values over two consecutive weeks of samples. Additionally, water sampling shows that the size of the bloom has significantly reduced in the Lakes. There is no longer any concern about toxin accumulation in bivalve species of shellfish from the Pseudo-nitzschia delicatissima algal bloom.”

The precautionary advice signs around the Lakes will be removed. Routine testing of algae levels in the Gippsland Lakes will continue on a weekly basis for at least the rest of the summer season.

People should not, however, consume fish found dead in the lakes. It's important to note that it is safe to eat any seafood and fish bought from local shops, served in cafes and restaurants or supplied by commercial fishers.
