Antimicrobial Resistance in Malaysian Shrimp Aquaculture and Strategies to Reduce Its Occurrence

Shrimp is a commercially important species in several regions and is among the key global aquaculture commodities essential for food production and security. Similar to most shrimp-producing countries, shrimp aquaculture in Malaysia suffers from recurring disease outbreaks that consequently impact the overall economy. The use of antimicrobial agents, particularly antibiotics, in shrimp aquaculture for prophylactic treatment and growth enhancement has increased the spread of antimicrobial-resistant bacteria in the aquatic environment. The development and dissemination of antimicrobial-resistant bacteria and other potential sources of antimicrobial contamination in waterways are facilitated by the continuous application of antibiotics in shrimp farming, municipalities, livestock, hospitals and pharmaceutical sources. This situation contributes to the spread of the antimicrobial resistance (AMR) phenomenon, a One Health issue with detrimental effects on human and animal health as well as the environment. Addressing the risks associated with AMR dissemination remains highly challenging due to the intensification of shrimp farming trends, which heightens disease outbreaks, and the limited availability of alternatives to antibiotics for many farmers seeking to prevent crop failure. In this review, we critically examine the key issues related to AMR in shrimp aquaculture and explore emerging treatment strategies. Our analysis encompasses a comprehensive review of the existing literature on the impact of AMR on shrimp farming in Malaysia, as well as alternative mitigation strategies aimed at fostering more sustainable and resilient aquaculture practices.
