Researchers in north Queensland are using DNA technology to investigate the effects of a mass fish escape.
Professor Dean Jerry, from James Cook University, says the ecological consequences of the escape of fish from farms and dams are not yet known.
But when up to 100,000 barramundi were lost from a North Queensland fish farm destroyed in Cyclone Yasi more than two years ago, it presented a unique opportunity to learn about the impacts and improve aquaculture practices.
