Antimicrobial resistance (AMR) demands collective action to reduce and mitigate its threats. The Quadripartite collaboration of the World Health Organization (WHO), Food and Agriculture Organization of the United Nations (FAO), United Nations Environment Programme (UNEP) and World Organization for Animal Health (WOAH) has led development and implementation of National Action Plans (NAPs) that describe approaches each country will take to tackle AMR. All antimicrobial users and sectors should be included, and the Quadripartite encourages a One Health approach. Aquaculture has received mixed coverage in NAPs: Here, we argue why aquaculture requires special consideration. Aquaculture is a diverse, global collection of industries and activities, with heterogeneity in systems and species greatly exceeding terrestrial food-animal production, with products traded internationally in huge volumes. Almost 6 % of global total antibiotic usage is estimated to be applied in aquaculture, with per-biomass quantities in some species exceeding usage in human and terrestrial food-animals. The watery nature of aquaculture interconnects it with other One Health compartments: humans, other animals and the wider environment. Rapid industry growth challenges relatively detached stakeholders such as regulators and NAP creators to remain abreast of changing practices, whilst support capabilities and capacity, e.g., health services, typically lag behind growing needs. To integrate aquaculture effectively into next-generation NAPs, ensuring policies cover the One Health spectrum, NAP creators need to recognise the diversity of aquaculture and initiate engagement across associated value chains, especially health service providers. Disentangling the industry can assist formulation of realistic policies for heterogenous contexts and identify pathways to implementation. Resource allocation must be appropriate and include relevant government departments, whilst improved ways to track and monitor AMR, including those international activities that impact AMR domestically, through suitable data collection are key to monitoring and evaluating policies. Better NAPs are crucial to addressing AMR and this coordinated global approach provides our best opportunity for success.
The COVID-19 global pandemic has had severe, unpredictable and synchronous impacts on all levels of perishable food supply chains (PFSC), across multiple sectors and spatial scales. Aquaculture plays a vital and rapidly expanding role in food security, in some cases overtaking wild caught fisheries in the production of high-quality animal protein in this PFSC. We performed a rapid global assessment to evaluate the effects of the COVID-19 pandemic and related emerging control measures on the aquaculture supply chain. Socio-economic effects of the pandemic were analysed by surveying the perceptions of stakeholders, who were asked to describe potential supply-side disruption, vulnerabilities and resilience patterns along the production pipeline with four main supply chain components: a) hatchery, b) production/processing, c) distribution/logistics and d) market. We also assessed different farming strategies, comparing land- vs. sea-based systems; extensive vs. intensive methods; and with and without integrated multi-trophic aquaculture, IMTA. In addition to evaluating levels and sources of economic distress, interviewees were asked to identify mitigation solutions adopted at local / internal (i.e., farm-site) scales, and to express their preference on national / external scale mitigation measures among a set of a priori options. Survey responses identified the potential causes of disruption, ripple effects, sources of food insecurity, and socio-economic conflicts. They also pointed to various levels of mitigation strategies. The collated evidence represents a first baseline useful to address future disaster-driven responses, to reinforce the resilience of the sector and to facilitate the design reconstruction plans and mitigation measures, such as financial aid strategies.
