Aquaculture at the crossroads of global warming and antimicrobial resistance

Antimicrobial resistance is responsible for some 700 000 deaths each year worldwide. In relation to this phenomenon, a team of researchers from IRD and CIRAD have raised the alarm regarding the development of antimicrobial-resistant bacteria in aquaculture, which is affecting fish production and human health worldwide. Their study, published in Nature Communications on 20th April 2020, established for the first time a link between global warming and an increased risk of antimicrobial resistance, and warned against inappropriate use of antibiotics.

Aquaculture – rearing aquatic organisms such as fish** and shellfish – plays a vital role in food security in many countries (it supplies more than half of the aquatic animals consumed by humans worldwide). It is particularly important for developing countries, for instance in Asia, which accounts for 90% of global output.

Fish farmers use large quantities of antimicrobials to treat or prevent disease on their farms. However, when used inappropriately, antimicrobials are ineffective and foster the development of resistant bacteria.
