Sustainable aquaculture through the One Health lens

Abstract

Aquaculture is predicted to supply the majority of aquatic dietary protein by 2050. For aquaculture to deliver significantly enhanced volumes of food in a sustainable manner, appropriate account needs to be taken of its impacts on environmental integrity, farmed organism health and welfare, and human health. Here, we explore increased aquaculture production through the One Health lens and define a set of success metrics — underpinned by evidence, policy and legislation — that must be embedded into aquaculture sustainability. We provide a framework for defining, monitoring and averting potential negative impacts of enhanced production — and consider interactions with land-based food systems. These metrics will inform national and international science and policy strategies to support improved aquatic food system design.
