A number of nations are prioritising the link between fisheries and aquaculture and nutrition and public health policies, thereby marking an increased recognition of the role of aquatic foods in sustainable healthy diets.
A new study led by WorldFish and the Stanford University Centre for Ocean Solutions assessed the alignment of objectives in national aquatic food systems and public health nutrition policies. It found that 77 of 158 national fisheries and aquaculture policies identified nutrition as a key objective in the sector. A further 68 of 165 public health nutrition policies identified the importance of fish and other aquatic foods consumption as key objectives.
The study reveals a positive trend in policy that prioritises aquatic foods to nourish nations, said co-author and WorldFish’s global lead for nutrition and public health Dr Shakuntala Thilsted.

“It shows the growing recognition of the crucial role aquatic foods have in people’s nutrition and health. It calls for the increased focus of policies in this area. It also marks a widening in fisheries policy beyond the traditional focus of production, economic efficiency, resource management and environmental issues.”
Fish has big potential
Aquatic food animals, plants and microorganisms harvested and farmed from water are rich in micronutrients and essential fatty acids crucial to human health.
Fisheries and aquaculture are increasingly recognised for their capacity to contribute to reducing global micronutrient deficiencies and diet-based health risks.
In the last decade, the research community in fisheries and aquaculture has developed a strong focus on the nutritional contribution that aquatic foods make to human nutrition, noted co-author Dr Eddie Allison, WorldFish’s director of science and research for aquatic food systems.
“We wanted to see if all this research was being reflected in policy and practice: Are food and nutrition programmes around the world including fish and other aquatic foods?
“Are fisheries management agencies and departments prioritising or even acknowledging the role that aquatic foods play or could play in ending malnutrition?”
Lead author Dr Zach Koehn, early-career fellow at the Stanford Center for Ocean Solutions, explained, “When we embarked on this study, we assumed there would be a lack of coherence between the two sectors. While we found that to be true in most countries, there was also a promising trend, with more recent policies showing higher alignment for both fisheries and public health and nutrition policies.”
Systematic policy approach
The researchers revealed the more recent policies were more likely to be associated with improved coherence among sectors.
Findings show nations that do not make the link between aquatic food systems and health policies have higher rates of obesity and malnutrition, leading authors to call for targeted policies to realise the potential contribution of nutrient-rich aquatic foods to healthier food systems.
Researchers recommended systematic policy approaches that promote greater coherence between the sectors in a bid to counter stubborn malnutrition rates, especially in low- and middle-come countries.
Allison said a transition to sustainable healthy diets that include an array of aquatic foods requires coherent policy and strong and inclusive institutional and legal frameworks.
“The integration of national policies reduces inconsistencies and promotes synergies among government departments and agencies, which encourage nutrition programmes like school feeding programs to include nutritious foods such as fish and other aquatic foods that can have generational impacts on health and wellbeing.”
Allison added, “With our co-author Shakuntala Thilsted being awarded the 2021 World Food Prize for her work on the nutritional contribution of fish to the diets of nutritionally vulnerable people in the low- and middle-income countries, and with WorldFish adopting a research agenda that is focused on food systems, nutrition and health, we are confident that research in this field is becoming increasingly influential and that we will see a rise in investment at the interface between aquatic foods and public health nutrition.”
