Many Small Island Developing States (SIDS) are experiencing a nutrition transition, wherein high prevalence of malnutrition co-occurs with growing rates of diet-related non-communicable diseases. Sustainably managed and accessible aquatic foods can serve as a rich and bioavailable source of nutrients, helping communities achieve healthy diets and meet key sustainable development goals (e.g., SDG 1 No Poverty, SDG 2 Zero Hunger, and SDG 14 Life Below Water). However, to properly harness aquatic food systems in nutrition interventions, we must first understand aquatic food’s role in nutrient intake and adequacy. Here, using a nationally representative survey from Kiribati, we quantify the contribution of aquatic foods to nutrient intake and adequacy, and examine the spatial variability in nutrient intake adequacies. We find aquatic foods are the main contributors of most nutrients we examined, providing > 75% of vitamin B12, retinol, and heme iron, > 50% of niacin and total vitamin A, and > 25% of protein, vitamin E, potassium, and total iron consumed. Consumption of aquatic foods contributes to meeting key nutrient adequacies (e.g., niacin) and provides complete adequacy for vitamin B12 and protein. However, despite high aquatic food consumption, we find high levels of nutrient inadequacies (11 of the 17 nutrients with dietary reference intakes). Overall, our study quantifies the nutritional importance of aquatic foods in an emblematic SIDS, emphasizing their vulnerability to declining aquatic resources. We also highlight the need for cross-scale context-specific targeted nutrition interventions, even when aquatic food consumption is high, to enable SIDS to meet key SDGs.

Nutrient supply from marine small-scale fisheries
Abstract Over 2 billion people are unable to access safe, nutritious and sufficient food year-round. While global fisheries are considered key in providing essential nutrients to hundreds of millions of people around the globe, the specific contribution of small-scale fisheries to the nutrient supply given other available food supplies is unknown. Here, we combined multiple global databases to quantify the importance of marine small-scale fisheries to national-level nutrient supply of coastal populations. We found that, on average across assessed nutrients (iron, zinc, calcium, DHA + EPA and vitamins A and B12), small-scale fisheries contributed about 32% of overall global seafood nutrient supply, 17% of the nutrient supply from animal-sourced foods and 10% of nutrient supply from all foods. These global averages, however, underrepresent some key roles of ocean-based foods. Combining nutrient supply estimates with global estimates of inadequate nutrient intake, we found that about half of coastal countries that have a mean inadequate intake of at least 50% across assessed nutrients (iron, zinc, calcium, DHA + EPA and vitamins A and B12) rely on small scale fisheries for at least 15% of mean nutrient supply, and many rely on small scale fisheries for more than 30% of mean nutrient supply. Catch from small-scale fisheries is particularly important for the supply of vitamin B12, calcium and DHA + EPA, representing up to 100% of supply in selected countries. Our study demonstrates the significance of small-scale fisheries for nutritionally vulnerable coastal populations, emphasizing how effective fisheries management can contribute to public health.

Abstract Researchers and policymakers increasingly recognize the contribution of aquatic food systems, such as fisheries, to food security and nutrition. Yet governing fisheries for nutrition objectives is complicated by the multiple overlapping processes that shape availability and access to nutrients over time, including fishing sustainability, climate change, trade dynamics, and consumer preferences. Anticipating the impact of governance interventions to sustain or enhance nutritional benefits from fisheries entails accounting for these multiple interacting influences. We develop an analytical approach to link available data on aquatic foods production, nutrition, distribution, and potential climate impacts to evaluate the nutrition implications of fishery management and post-harvest allocation interventions. We demonstrate this approach using national and publicly available datasets for five case study countries: Peru, Chile, Indonesia, Sierra Leone, and Malawi. As examples, we evaluate the potential to enhance domestic supply of key nutrients to nutritionally-vulnerable populations by a) dynamically adjusting fishing effort in response to climate impacts on fish stocks, and b) retaining aquatic foods currently diverted via trade or foreign fishing. The results indicate substantial differences across countries in terms of anticipated climate change effects, with potential for substantially increased nutrition yield in Chile and Peru under adaptive management, vs. more modest yield increases in Indonesia. The impacts of post-harvest allocation policies related to foreign fishing, exports, fishing sector, and subnational trade also vary, with exports weighing heavily on nutrient availability in Sierra Leone. This methodological approach represents a step toward operationalizing calls to manage fisheries as part of national food and nutrient supplies, in light of climate change risks.more » « less

Seafood from marine fisheries, such as finfishes and invertebrates, is an important source of nutrients for billions of people globally. Seafood species vary in their micronutrient concentration, their economic value, and their vulnerability to exploitation and climate change. However, fisheries management has rarely considered the nutritional quality of fisheries catches and their relation to economic, conservation and climate vulnerability dimensions. Here, we quantified and analysed the micronutrient supply and average micronutrient concentration of taxa exploited by fisheries in the Indian Ocean. We also assessed associations among taxon‐specific micronutrient concentrations, ex‐vessel prices, fishing vulnerability and climate vulnerability. We found that small pelagic finfishes, despite contributing little to the overall catch weight, were particularly rich in micronutrients, were resilient and low priced, highlighting their utility in food and nutritional security. In contrast, taxa such as tunas and cephalopods were less nutrient‐dense, more vulnerable and had higher ex‐vessel prices. Results also showed differences in catch micronutrient concentrations between countries within the Indian Ocean Rim (IOR) and Distant Water Fishing (DWF) countries. IOR country catches were dominated by taxa richer in calcium, omega‐3 fatty acids and iron but with higher climate vulnerability. DWF catches, which accounted for only 2% of the Indian Ocean's total micronutrient supplies, were relatively richer in selenium, more vulnerable to fishing and had higher ex‐vessel prices. Our results highlight the trade‐offs and synergies among nutritional, economic, conservation and climate resilience dimensions of Indian Ocean fisheries, providing key insights for nutrition‐sensitive fisheries management strategies aimed at balancing multiple priorities.more » « less

Abstract Microalgae are the main source of the omega‐3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), essential for the healthy development of most marine and terrestrial fauna including humans. Inverse correlations of algal EPA and DHA proportions (% of total fatty acids) with temperature have led to suggestions of a warming‐induced decline in the global production of these biomolecules and an enhanced importance of high latitude organisms for their provision. The cold Arctic Ocean is a potential hotspot of EPA and DHA production, but consequences of global warming are unknown. Here, we combine a full‐seasonal EPA and DHA dataset from the Central Arctic Ocean (CAO), with results from 13 previous field studies and 32 cultured algal strains to examine five potential climate change effects; ice algae loss, community shifts, increase in light, nutrients, and temperature. The algal EPA and DHA proportions were lower in the ice‐covered CAO than in warmer peripheral shelf seas, which indicates that the paradigm of an inverse correlation of EPA and DHA proportions with temperature may not hold in the Arctic. We found no systematic differences in the summed EPA and DHA proportions of sea ice versus pelagic algae, and in diatoms versus non‐diatoms. Overall, the algal EPA and DHA proportions varied up to four‐fold seasonally and 10‐fold regionally, pointing to strong light and nutrient limitations in the CAO. Where these limitations ease in a warming Arctic, EPA and DHA proportions are likely to increase alongside increasing primary production, with nutritional benefits for a non‐ice‐associated food web.more » « less

Abstract Purpose of ReviewAquatic foods are increasingly being recognized as a diverse, bioavailable source of nutrients, highlighting the importance of fisheries and aquaculture for human nutrition. However, studies focusing on the nutrient supply of aquatic foods often differ in the nutrients they examine, potentially biasing their contribution to nutrition security and leading to ineffective policies or management decisions. Recent FindingsWe create a decision framework to effectively select nutrients in aquatic food research based on three key domains: human physiological importance, nutritional needs of the target population (demand), and nutrient availability in aquatic foods compared to other accessible dietary sources (supply). We highlight 41 nutrients that are physiologically important, exemplify the importance of aquatic foods relative to other food groups in the food system in terms of concentration per 100 g and apparent consumption, and provide future research pathways that we consider of high importance for aquatic food nutrition. SummaryOverall, our study provides a framework to select focal nutrients in aquatic food research and ensures a methodical approach to quantifying the importance of aquatic foods for nutrition security and public health.more » « less
