LATEST monthly water quality testing in Port Curtis have continued to find no evidence to link water quality with any adverse effects on fish health.
The Department of Environment and Heritage Protection released the results of February and March water sampling in Gladstone Harbour on Wednesday night.
Director-General Andrew Chesterman said the monthly monitoring program, which began last September, was expanded in February from 32 to 47 sites, in line with recommendations made by the Gladstone Fish Health Scientific Advisory Panel.
The monitoring program was expanded to determine any effects of existing large industrial activities on water quality in Gladstone, and also includes sites across the broader region.
"The water quality results from the extended sampling are similar to those in previous reports, and based on the evidence, there remains no clear link between water quality and fish health in Gladstone waterways," Mr Chesterman said
