World Aquaculture - December 2012

WWW.WAS.ORG • WORLD AQUACULTURE • DECEMBER 2012 61 and improved biosecurity. Biofloc technology systems have high efficiency, productivity, sustainability and lower FCR. By using this novel technology, the blue revolution in aquatic systems can be achieved in a sustainable manner. Biofloc technology increases pond productivity. A global effort is needed to optimize, integrate and disseminate this appropriate, emerging technology.
