Aquaculture systems are complex and influenced by environmental changes, cultural, human behavioural and socio-economic factors. In low and middle-income countries the intensification of aquaculture production is likely to drive indiscriminate use antibiotics to treat or prevent diseases and or to increase productivity, often to compensate for deficiencies in management and husbandry.

Project Overview

A systems-thinking approach was undertaken to map components, interactions and flow of products in two commercially important aquaculture systems in Vietnam. The aim was to identify hotspots for the emergence and selection of antibiotic use and hotspots for human explore to antibiotics, antibiotic resistant bacteria and antibiotic resistant genes, as well as identify potential drivers of antibiotic use and interventions to reduce antibiotic use and antibiotic resistance in striped catfish and white-leg shrimp production. 

Research Impact

The findings of this study have provided a platform to quantify risks at different time points, understand the interaction of the various components, identify key stakeholders who can lead and implement changes. Furthermore, the maps generated can be used to understand the flow of antibiotics, antibiotic resistance bacterial and antibiotic resistance genes in the system. 

This study has demonstrated that the application of integrated and inter-disciplinary approach to characterize antibiotic use in aquaculture by using systems thinking and mapping by stakeholders has been successful in providing a platform to quantify risks a
