21 Nov 2017 --- New research from WorldFish undertaken as part of the CGIAR Research Program on Fish Agri-food Systems (FISH) identifies means to lessen the use of antimicrobials, such as antibiotics, antivirals, and antiprotozoals, in aquaculture. Intensification of fish farming systems has resulted in higher risks of disease outbreaks and a subsequent trend towards more antimicrobial use the report says.
