Seqwater has advised fishers to release and not eat fish from Hinze Dam because of naturally-occurring mercury.
Queensland Health has warned that fish caught in the dam are not suitable to eat due to elevated levels of naturally-occurring mercury in longer-lived fish.
This follows recent results from routine Seqwater fish testing.
The level of mercury in the water is low and well within safe limits for drinking.
An Seqwater spokesman said fishing in Hinze Dam should be catch-and-release only.
