Prawn problems perplex farmers

Biosecurity Queensland experts have been left scratching their heads with what to do next after the outbreak of White Spot disease in Logan rivers.

Chlorine had to be dumped in more than a hundred prawn ponds across five rivers last year when the disease began to spread.

It killed off 1500 tonnes of the animal, which was then left to rot in the water.

Farmers have told Newscorp no one knows how to get the contaminated water and prawns out of the ponds without the risk of polluting surrounding waterways.
