Shellfish warning over algal bloom
ONGOING algal blooms have prompted warnings about eating shellfish from the Swan River.
The Department of Parks and Wildlife continued to warn people about the health risks of people consuming shellfish from areas where Karenia-type dinoflagellate algae levels are elevated.
Fish kills are also a possibility in the Canning River near Riverton and the Swan River near Bayswater where Karlodinium, a dinoflagellate, is moderately high.
This species presents no direct human health concerns but the Department of Health advises people to avoid swimming in water that looks discoloured, murky or smells unpleasant.
Remco van Santen, of My Clean River which was formed in July last year, said the river’s health had been in decline for decades and referred to his report that claimed before the State Election that the river’s health was an off-therecord political football.
He felt there was a greater opportunity for change with the new Labor Government and he was hoping to see different fertilisers used upstream in targeted areas.
He said the Karenia-type dinoflagellate was stimulated by fertilisers and animal waste.
He also wants land use for animal and recreational activities to be reviewed, notably horse and cattle, which contribute about one-third of the pollution.
Mr van Santen wants to see Aboriginal people involved in addressing the issues, and an information and tourist centre built for the Swan River.
Questions for Environment Minister Stephen Dawson were directed to DPaW, which said the Government committed $300,000 a year for community groups engaged in rivercare projects.
“The Department of Parks and Wildlife has been working with other government agencies and natural resource management (NRM) groups in the Avon Catchment on programs to improve fertiliser efficiency and soil health,” a department spokeswoman said.
Call FishWatch on 1800 815 507 to report any dead or sluggish fish in the river.
Remco van Santen, of the group My Clean River, would like to see changes to bring the Swan back to health.
