One Health in Aquaculture

Aquaculture is one of the fastest growing and highly traded food sectors, and will become increasingly important in future food systems. This Collection highlights research and commentary on sustainable development of the aquaculture sector incorporating One Health principles - recognising the interconnected health and well-being of people, animals, plants and their shared environment.

Comment and Opinion

By 2050, the majority of aquatic dietary protein will be produced by the aquaculture sector. A set of 15 metrics are presented here to guide the industry sustainably through the rapid growth and development it is experiencing.

Perspective | | Nature Food

Aquaculture must develop within planetary boundaries. Experience from agriculture, such as in managing monocultures and using genetically modified crops, can inform sustainable solutions for aquaculture.

Perspective | | Nature Food

Mariculture has attracted much attention as a potential new source of food. Yet, the trophic efficiency of marine ecosystems is already high, making further improvements hard to achieve. Increasing marine food production may be possible by fishing at lower trophic levels, but the risks of such a practice must be considered.

Comment | | Nature Food

There is an urgent need to ensure that marine ecosystems are able to support biodiversity and the services they sustain in the face of rapid global change. Here, the authors argue that a holistic approach of integrated ocean management can ensure a sustainable and resilient ocean economy.

Perspective | | Nature Ecology & Evolution

Marine aquaculture is widely proposed as compatible with ocean sustainability, biodiversity conservation, and human nutrition goals. In this Perspective, Belton and colleagues dispute the empirical validity of such claims and contend that the potential of marine aquaculture has been much exaggerated.

Research and Reviews

Aquaculture production systems in Bangladesh were configured to optimize the supply of micronutrients while minimizing environmental impacts. Increased production of small indigenous species enabled nutrient densities of farmed fish to match those of wild-caught fish, and systems that co-produce fish and rice had the lowest environmental burdens.

Novel aquaculture feeds are rapidly developing, but their contributions to sustainable industry growth are unknown. Cottrell et al. model feed efficiency and fatty acid profiles, showing that replacing forage fish with novel feed ingredients could strengthen aquaculture’s role in global food security.

Analysis | | Nature Food

Omega-3 fatty acids are important for the human diet and for some aqua and animal feeds. This study reports a supply gap, and using quantitative systems analysis identifies targets for increasing efficiency in the global omega-3 cycle.

Brief Communication | | Nature Food

Global environmental changes threaten many food-producing sectors, including aquaculture. Here the authors show that countries most vulnerable to climate change will probably face the highest antimicrobial resistance in aquaculture-related bacteria, and that infected aquatic animals have higher mortality at warmer temperatures.

Aquaculture is surpassing wild-caught seafood, but we feed aquaculture with wild forage fish for key nutrients. This study finds removing such forage fish from diets of livestock and non-carnivorous aquaculture species and moderating its use in China will help sustain forage fish populations in the future.
