Global trends in antimicrobial use in aquaculture

D. Schar, E. Y. Klein, et al.

This study by Daniel Schar, Eili Y. Klein, Ramanan Laxminarayan, Marius Gilbert, and Thomas P. Van Boeckel examines global antimicrobial use in aquaculture, projecting a 33% increase by 2030. With significant implications for ecosystem health and food animal use, the findings emphasize the critical need for improved antimicrobial stewardship in this rapidly growing sector.

Abstract

This study estimates global trends in antimicrobial use in aquaculture in 2017 and 2030. Global antimicrobial consumption in aquaculture in 2017 was estimated at 10,259 tons, projected to increase 33% to 13,600 tons by 2030. The Asia-Pacific region accounts for the majority of global consumption. Antimicrobial consumption intensity varied across species groups, with catfish showing the highest intensity. All antimicrobial classes identified are medically important. Aquaculture constitutes 5.7% of aggregate global human, terrestrial, and aquatic food animal antimicrobial use in 2030 but has the highest use intensity per kilogram of biomass. The study highlights the urgent need for enhanced antimicrobial stewardship in aquaculture due to its rapid growth and links to ecosystem health.
