Moreton Bay water quality fear; call for investigation

A FISHERIES biologist has called for an urgent investigation into Moreton Bay water quality after months of complaints about dead marine mammals, heavy metals, mangrove dieback and polluted water.
John Thorogood said reports of up to 20 dolphins, dugong and turtles dying in the bay off Brisbane over the past three weeks, and pollution issues, raised questions about the health of one of Queensland's most significant coastal regions.
RAAF Base Amberley revealed on Monday that heavy metals had been found at its sewage treatment plant in Warrill Creek, which flows into the Bremer and Brisbane rivers and Moreton Bay.
In June, University of Queensland wetlands specialist Norm Duke said pollution may have killed up to 6000ha of mangroves, while in March 62 tonnes of fertiliser and 270 tonnes of oil were spilled off Moreton Island from the Pacific Adventurer.
Last month a diver reported murky green sea conditions off the island and questioned whether this could have been caused by the fertiliser.
But Environment Department chief scientist Col Limpus said the number of dolphin, dugong and turtle deaths was not unusually high.
"While a number of deaths have been reported in a small timeframe, historically there is a peak in strandings from August to October," Dr Limpus said. "This is believed to be related to animals in poor condition not surviving the winter."
In answer to a question on notice by the LNP's Peter Dowling, Sustainability Minister Kate Jones told Parliament that from 2000 to May this year, 2347 turtles, dugong and dolphins had been found dead in the bay.
In the five months to May this year 138 turtles were found dead, four dugong and two dolphins but since then at least five dolphins, two dugong and about 10 turtles had washed up.
Wildlife Preservation Society of Queensland president Simon Baltais said the issue was of great concern, especially since the Government had tried to fob it off.
Many green turtles also have papilloma virus, a disease in which often fatal growths form around their mouths, eyes and legs.
