- Comprehensive but interpretable assessment of the environmental performance of diets involves choosing a set of appropriate indicators. Current knowledge and data gaps on the origin of dietary foodstuffs restrict use of indicators relying on site-specific information. This Personal View summarises commonly used indicators for assessing the environmental performance of diets, briefly outlines their benefits and drawbacks, and provides recommendations on indicator choices for actors across multiple fields involved in activities that include the environmental assessment of diets. We then provide recommendations on indicator choices for actors across multiple fields involved in activities that use environmental assessments, such as health and nutrition experts, policy makers, decision makers, and private-sector and public-sector sustainability officers. We recommend that environmental assessment of diets should include indicators for at least the five following areas: climate change, biosphere integrity, blue water consumption, novel entities, and impacts on natural resources (especially wild fish stocks), to capture important environmental trade-offs. If more indicators can be handled in the assessment, indicators to capture impacts related to land use quantity and quality and green water consumption should be used. For ambitious assessments, indicators related to biogeochemical flows, stratospheric ozone depletion, and energy use can be added.

- The global food system is facing the challenge of producing sufficient nutrients to accommodate future demands within planetary boundaries, while reducing malnutrition. Although nutrient-rich seafood can play a prominent role in resolving this challenge, seafood from capture fisheries is currently partly wasted. Here we quantified the nutrient contribution from capture fisheries through a hypothetical scenario that assumed all captured seafood and byproducts from seafood processing would be used for human consumption. Our simulations show that available seafood per capita can be doubled without increasing the pressure on global fisheries when all reported, illegal, and discarded capture is used as food, complemented with processing byproducts. In such a scenario, seafood contributes greatly to daily nutrient requirements – e.g., omega-3 can be fully met. Although uncertainty should be considered, these results indicate that putting the whole fish on the table can increase nutrient availability from capture fisheries substantially and sustainably.

The role of fisheries and fish farming in a circular food system in the European Union

- Studies that demonstrated animals can contribute to resource efficient food supply, by upcycling low-opportunity-cost feed (LCF), into valuable animal-source food, focussed solely on livestock (ruminants, pigs and poultry). Aquatic animals, however, also make valuable contributions to food supply, especially as they are our main natural source of eicosapentaenoic (EPA) and docosahexaenoic (DHA) ω-3 fatty acids. Our aim, therefore, was to assess the contribution of capture fisheries and fish farming (salmon and tilapia) to human nutrient supply in EU-28 (before Brexit), when feeding no biomass from arable land or waterbodies but only LCF to livestock and farmed fish. To this aim, we deployed an optimisation model allocating available LCF in the EU under various scenarios, to that combination of fish and livestock that maximises human digestible protein supply, while meeting human requirements of vitamin B12 and EPA + DHA. We found that capture fisheries could fulfil maximally around 40 % of daily per capita EPA + DHA requirements in EU28. This contribution would already require rebuilding fish stocks and prioritising edible fish for human consumption. To meet our EPA + DHA requirements we, thus, need to additionally farm fatty fish (salmon). Our results show that, when feeding only LCF, these fatty fish depend on by-products from fisheries to meet their own EPA + DHA requirements and on livestock slaughter by-products to meet their high protein requirements. Feeding livestock by-products to farmed fish, however, is not common practice due to concerns about consumer acceptance. We also demonstrate that upcycling LCF into valuable human food requires a proper balance of different farmed fish and livestock systems, tailored to the available LCF and desired nutrient supply to the human population. Overall, our results provide insights into the role of aquatic animals across land and water to human nutrient supply and give a direction for strategic sustainability development of both capture fisheries and fish farming.
