Researchers in Queensland, Australia are using DNA technology to study the impact of fish escapees.
The effect of mass escapes from fish farms is not documented so when up to 100,000 barramundi were lost from a North
Queensland fish farm destroyed in Cyclone Yasi two years ago, researchers saw an opportunity to learn more.
Professor Dean Jerry and a team from James Cook University are working with
recreational and commercial fishers in order to extract DNA from the
fins of fish caught in the Hinchinbrook Channel, near Cardwell.
DNA parentage analysis is used to determine if fish
have derived from broodstock parents known to have been used to breed
the fish stocked into the farm.
