Over 3 billion people relay on oceans across the world. The ocean resources serve as a food and employment, covering directly or indirectly over  300 million people. Oceans account for over 3 trillion dollars of global GDP, act as carbon sinks which absorb 30% of global carbon emissions, and are the largest primary source of proteins to billions of people. All along the coast, fishing villages are populated by people dependant directly and indirectly on fishing and other coastal livelihoods. India has about 500 fishing villages where one million fishermen are involved in fishing. While an additional one million fishermen are involved in fishing allied activities such as making and repairing fishing nets, curing the catch, peeling, and other processing issues. Fishing in India is still largely done by employing traditional fishing methods and of the nearly one million families that are involved in fishing, 91.3% are traditional fisher folk. Out of this, more than half a million   households (over 61%) are below the poverty line. The economic potential of the oceans is expected to double from India about one trillion in 2010 to US two trillions by 2030. Ocean resources (Blue foods) are viewed as lucrative areas for increased investment, including in fisheries, aquaculture, bio-prospecting, renewable energy, oil and gas, and other businesses. India is the second largest fish producing nation in the world and has a fleet of 250,000 fishing boats. India’s coastline extends to 7,500 kms. Nine Indian States have access to the coastline. The Government had established the ‘Fisheries and Aquaculture Infrastructure Development Fund‘ (FIDF) in 2018-19 with a fund size of INR  7 billion to provide concessional credit to State/UT Governments and the private sector to fill significant gaps in the fisheries infrastructure. The Government of India also launched the Pradhan Mantri Matsya Sampada Yojana (PMMSY), in May 2020, with an investment of  US$ 5 billion  to bring about a Blue Revolution through sustainable and responsible development of the fisheries sector. In the backdrop of the United Nations Decade of Ocean Science for sustainable development, the present work  is considered to elucidate the potential of Indian coast in the nexus of Fish, water and society  and the ramifications of the anthropogenic activities.

The Philippine archipelago hosts a long range of coastlines where coral reefs provide food and livelihoods for millions of people. Despite this direct access to food sources, food insecurity is widespread in the country. Using mixed methods and an “ocean to plate” approach, we investigate the role of fish in the food and nutritional security of coastal communities in five districts of Palawan, Philippines, by analyzing the patterns of fish production, distribution and consumption. We demonstrate that: i) fish production shows large disparities per village, ranging from 79 tons to 614 tons per year, whereas average per capita consumption ranges from 51 kg to 58 kg annually, suggesting that production satisfies local demand across the districts; ii) despite this result, local communities perceive a scarcity of fish, since 34-80% of the fish produced in these districts are exported, and a large part of the population is food insecure; and iii) the consumption of reef and pelagic fish has significant correlation to higher intakes of energy, protein, and micronutrient nutrient requirements. Improving fish consumption would therefore help tackle food insecurity. Involving the communities in data collection and the discussion of these results helped us formulate management recommendations that fit their context and improves the accessibility of fish. We emphasize how our holistic approach to coastal food systems through the mobilization of diverse data sources can yield more contrasted results than those focusing on a single dimension such as production. This is crucial to the formulation of relevant management advice to thrive for equity and sustainability.

The sustainability of ocean-based food systems is essential for coastal communities, especially those dependent on fisheries and mariculture, such as the Gulf of Nicoya in Costa Rica. Due to the depletion of fishery resources through overexploitation and climate change, mariculture, and in particular oyster farming, has emerged as a sustainable alternative that offers new economic opportunities for local communities. However, these systems face critical challenges, including pollution and degradation of the marine ecosystem, which affect both the quality of the product and the health of those who depend on this activity. Given the need to ensure the sustainability, equity and security of this food system, a project was developed with the main objective of strengthening mariculture in the Gulf of Nicoya through a study of environmental variation in oyster cluster and shrimp farming sites. The project analyses  water, sediments and oyster soft tissue by standardized methods to identify contaminants such as lead, cadmium, arsenic and mercury, as well as pathogenic microorganisms in both water (Enterococcus faecalis, fecal coliforms and Clostridium perfringens) and soft tissue of these organisms (Escherichia coli, Salmonella spp, Staphylococcus aureus, total aerobic counts, Vibrio parahaemolyticus and Listeria monocytogenes) without safety treatment; demonstrating the influence that anthropogenic activities from the mainland have on the marine ecosystem, for example heavy metals were found in sediment with the following ranges As: 45. 4 -49.9 µg/L; Cd: 0.317 - 1.40 µg/L; Pb: 9.68 - 60.7 µg/L, that may generate bioaccumulation at different trophic levels. At microbiological level, the maximum permitted ranges of the Central American technical regulation RTCA 67.04.50:08 for fresh marine products in mollusks were exceeded, constituting a food safety risk if not treated before consumption. This project provides scientific inputs that allow the communities of the Gulf of Nicoya to make informed and sustainable decisions in their mariculture practices, contributing to the quality of the final product and the protection of their environment. Thus, this effort strengthens food security by providing a system based on up-to-date environmental information that mitigates risks and promotes marine production in balance with the environment. The findings demonstrate the urgency, importance and vigilance of greater regulation in environmental management policies for land-based activities that affect the quality of marine life and, therefore, that of coastal communities, highlighting mariculture as a key activity for sustainable development. The proposal encourages a shift towards more responsible practices, adjusted to the effects of climate change, and offers an essential tool for the monitoring and adaptation of these productive activities.

This study was conducted to assess the effect of the green macroalgae Ulva lactuca and black soldier fly larvae (Hermetia illucens, L.) on the growth performance and feed utilization of Nile tilapia (Oreochromis niloticus). Four experimental diets containing different proportions of Ulva lactuca and black soldier fly larvae were developed to meet the nutritional requirements of Nile tilapia (approx. 21.7 MJ/kg gross energy). Diets were tested in triplicate. The fish were fed three times a day at 9:00 am, 1:00 pm and 5:00 pm for 45 days.

A total of 360 Tilapia juveniles with an average weight of 12.72± 0.3g and an average length of 8.86 ± 0.5cm were stocked in twelve rectangular tanks fed by a recirculating aquaculture system.  Each tank (0.8 meter cube) had a water volume of 300 L/500 and was stocked with 30 fish, giving a density of around 0.1 g/L. During the acclimatization period (15 days), Tilapia were fed to satiation with a commercial feed (2mm, Protein 28%, Mineral matter 20%, Fat & oil 5%, Moisture 12%). During the experimental period (2 weeks), the physico-chemical parameters of the water were regularly checked using the Hanna Oximeter, the HI-gghhh Aquaculture Photometer. Temperature (19.5 ± 0.3°C), dissolved oxygen (5.77 ± 0.6 mg/l), pH (7.2 ± 0.3), Amonia NH3 0.28 mg/l, nitrite NO2 <0.01mg/l. Phosphate (0.44 ± 0.01mg/l) and Alkalinity CaCO3((184 ± 0.3mg/l). In order to maintain pH at 7, a permanent supply of fresh water was provided in the ratio (2:1). The effect of the four experimental diets on the growth performance and feed utilization of Nile tilapia will be measured on fish performance, including weight gain, specific growth rate, feed conversion index and other parameters such as K coefficient. After 5 weeks, the fish had an average weight gain of 6.19 ± 0.2 g and an average length gain of 1 ± 0.1 cm.

 At the end of the feeding trial, we found that feed 1 with the following formula: 50% black soldier fly larvae meal + 25% Ulva lactuca mix + 25% fish meal, tested in tanks 1, 2 and 3, performed better than the other feeds.

Small-scale fisheries are vital to Madagascar's coastal communities, providing livelihoods, food security, and economic opportunities. Yet, these fisheries are often undervalued and unmanaged due to limited data.  With the growing establishment of Marine Protected Areas (MPAs) in Madagascar, gaining insights into how fishing practices interact with socio-ecological dynamics has become increasingly important for effective management. However, no study to date has offered a comprehensive regional comparison of catch per unit effort (CPUE). To address this gap, we investigated the effects of gender, gear use, reserve status, and fishing revenue on regional CPUE trends. We used CPUE data collected by trained local fish collectors, from 2023 to 2024, through Kobo Toolbox standardized surveys, encompassing over 8,100 fishing trips across 18 villages in three regions (Southwest, Northwest, and Northeast). Collectors, primarily women, documented fishers’ gender, age, hours at sea, fishing locations, gear types used, and identified, counted, and weighed each organism caught twice a week. We anticipate regional differences in CPUE trends, with higher values in areas where women contribute substantially to the catch and in regions where villages participate in protected area agreements, as reserves may promote more sustainable fish populations through reduced fishing pressure and spillover effects. These findings will improve understanding of the regional factors that influence CPUE, supporting more inclusive and effective management strategies for sustainable fisheries. By examining these trends alongside community perspectives, we hope to understand how fishing practices and CPUE relate to opinions on and participation in MPA management across these categories, fostering more inclusive management approaches. Although this research focuses on Madagascar, it will provide valuable insights for conservation organizations working on small-scale fisheries and MPA management globally.

The study is an analysis of artisanal fisherwomen and their strategies to meet family nutritional needs, their socio-ecological and economic contributions within the supply chain and their role in promoting sustainable fishing and local food sovereignty.

Rising ocean temperatures, acidification, pollution and overfishing have led to changes in coastal marine ecosystems. In addition, hurricanes and droughts have impacted negatively the populations in coastal areas, fishing infrastructure, and the communication routes (FAO, 2024), including the seafood capturing processes, fishing operating costs, and the population's ways of living (FAO, 2023).

In the Canton of Puerto Jiménez, located in the Province of Puntarenas, Costa Rica, about 30 artisanal fisherwomen who are building creative climate change adaptation strategies (Viña, 2022) in conditions of great socio-environmental vulnerability, unemployment, little education and state abandonment, have been identified. For 15% of these censused fisherwomen, artisanal fishing is part of a basic supply chain contributing to the family economy, and for the remaining 85%, artisanal fishing is only for self-consumption. This lifestyle provides both; food for families and the sustainability of marine ecology (Solórzano, Ayales and Solís, 2016).

Many fisherwomen have informal jobs, hence complement the fishing activity with the sale of handicrafts, food, agricultural products, while performing domestic and unpaid care work. (Lamb, 2024). While fishing, they face patriarchal structures related to: marketing of seafood, limited political participation in decision-making, marketing of products, training and attention to the nutritional needs of the family, among others. Thus, it is difficult to quantify these women’s economic contribution to artisanal fishing and their unpaid daily chores.

For these reasons, a multilevel study related to the participation of the artisanal fisherwomen in food sovereignty and the basic supply chain will be carried out. From the intersectional feminist theory (Viveros, 2023), an analysis of gender roles in artisanal fishing, access and control of fishing resources, resilience to climate change, sustainable artisanal fishing practices, among others, will be developed.

With the mixed, participatory and decolonial methodology (Guerra, 2018), a microlevel analysis will be carried out on the perceptions about the role of women in artisanal fishing, the basic supply chain and food sovereignty.

At the meso level, the interactions between families and community groups that share coastal marine areas for artisanal fishing and the construction of certain supply chains will be examined.

Finally, at the macro-level, the analysis would deal with the institutional structures related to Public Policies that grant these women sovereignity over Decision Making in the Canton of Puerto Jiménez.

The results generated will be used to present a series of recommendations that will promote food sovereignty to the supply chain practiced by women, taking into account sustainable fishing practices, local and regional support networks, participation in political decision-making, access to nutritious seafood, the conservation of traditional knowledge about sustainable fishing and marketing at a fair price, among others.

The secondary data collection involving fisherwomen was conducted over the year 2024.

In Madagascar, food insecurity has increased considerably over the last ten years, affecting almost 33% of the population in 2022, or around 8.8 million people. To better understand the contribution of the coastal and inland small-scale fishery (SSF) sector to food supply, we carried out a multidisciplinary study in 2022 as part of the Illumating Hidden Harvest (IHH) worldwide program. We combined analysis of fishery statistics from the Ministry of Fisheries and the Blue Economy (MPEB), a review of previous research studies on small-scale fisheries in Madagascar, and a field survey in seven coastal and inland regions through in-depth interviews with fishers and community members about value chains, livelihoods, and food systems. The results showed that around 242,000 fishers (both men and women) are directly involved in small-scale fisheries in more than 2,500 villages across the country. Fish products form this sector accounted for 59% of national fish production and provided a vital source of nutrients (e.g., proteins, iron, calcium and omega-3s) to the Malagasy population, and more particularly in coastal fishing villages. In economic terms, the sector provided income for nearly 1.5 million people and contributed 6.6% of overall Malagasy exports. As an accessible, healthy, and major source for food, SSF also plays a fundamental role in food and nutritional security across the country through inland market networks. However, the sector faces major challenges, including coastal habitat degradation (e.g., in mangrove and coral reef ecosystems), the likely effects of climate change, and increasing fishing pressure due to population growth and rising domestic and export market demand. Appropriate management strategies and policy are therefore needed to enhance and sustain SSF and minimize post-harvest loss. Promoting the Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries (SSF Guidelines) can support the establishment of inclusive governance frameworks and good resource management practices. Strengthening the commitment and implementation of these Guidelines can therefore help strengthening SSF’s contribution to food systems and, consequently, securing food security and sovereignty and poverty eradication in Madagascar.

Demands for fishery resources in Africa have been rising over the past few decades. Yet, fishery and aquaculture production in Southern Africa show contradictory patterns. The total fish catch in Africa grew until 2018, but has since remained relatively stable with marginal changes. On the other hand, the fish catch in South Africa has been in a declining trend. There was a significant gap in the development of aquaculture in Africa, and aquaculture production remains limited, except in Egypt and Tanzania. In Southern Africa, both Angola and Mozambique have shown increases in fish catch. However, Mozambique’s seafood trade deficit has grown over the period from 2012 to 2022. Namibia and South Africa, on the other hand, have reduced their fish catch. Namibia imported more fish than it exported in 2022 compared to 2012, and South Africa has shifted to a seafood trade deficit.

Interviews conducted with stakeholders in Southern African countries—namely South Africa, Namibia, and Mozambique—from 2023 to 2024 revealed several important perspectives. Several factors have been identified. Increased fishing pressures from distant fishing vessels were considered a significant factor contributing to the decline in seafood production and self-sufficiency in Southern African countries. Countries are becoming increasingly vigilant about illegal, unreported, and unregulated (IUU) fishing. However, Southern African countries have limited capacity to monitor IUU vessels and enforce regulatory measures. Seawater warming is another factor that may have disrupted fish migratory patterns and shifted habitats away from conventional fishing areas. Increased land-use changes and inland development have caused soil discharge and sedimentation, disturbing fish habitats. Additionally, increased exports of valuable seafood could also result in less valuable seafood being imported from neighboring or overseas countries.

Marine environment monitoring in the West Indian Ocean also revealed that there are patches of ocean areas showing different patterns of sea surface temperature changes. It is not the case that all areas in the West Indian Ocean exhibit a linear trend of seawater warming. In fact, some areas show a decline in seawater temperature. These mixed trends make it difficult to assess fish biomass availability and predict future trends across the Indian Ocean.

South Africa leads aquaculture development in Southern Africa. However, its production is focused primarily on lucrative delicacies such as abalone, which are exported to Asian markets. Local aquaculture is not intended to support the local seafood market but rather to generate revenue from seafood exports. The implications of export-oriented seafood sector development need to be further analyzed, particularly in terms of enhancing seafood production and ensuring food security in Africa. The current patterns of seafood exports and their socio-economic benefits also need to be examined. Policy transformation is required to optimize balanced seafood sector development, promote sustainable blue economies, and ensure food security in Southern Africa.

The blue foods industry remains underutilized in Kenya despite the vast aquatic and marine resources present. Whereas many Kenyans obtain their protein needs from terrestrial animals and birds compared to marine sources, there is great potential in aquatic and marine sources. Studies indicate that livestock farming is a major greenhouse gas accounting about 14.5% global methane emissions. Also, land-based animal farming requires huge investments in capital and operation costs putting pressures on farmers. Furthermore, climate change disasters such as droughts, diseases and floods have led frequent losses of animals exacerbating both economic and health challenges. Blue foods from freshwater and marine sources are cheap, easy to cultivate and sustainable compared to animals. In Kenya, blue foods sources are essential economic drivers providing livelihoods and employment. Blue foods provide healthy proteins and valuable nutrients. However, the potential of blue foods in Kenya is yet to be understood. In this study, , we provide the status of the blue foods industry in Kenya's coastal regions, focusing on the types of ocean-based products supplied, sales volumes, market demand, and the challenges associated with climate change. A survey of suppliers, including supermarkets, fish markets, and butcheries, highlights the sector’s potential for growth, its role in diversifying protein sources, and its contribution to climate change mitigation through reduced reliance on land-based animal proteins. The findings provide insights into the barriers to promoting blue foods, particularly in terms of consumer preference and sustainability, while emphasizing the role of ocean-based proteins in reducing methane emissions and enhancing climate resilience. This research aims to inform strategies for expanding the blue foods industry in Kenya, offering recommendations for sustainable practices, policy support, and climate adaptation in the face of growing climate-related challenges.

The aim of this paper is to examine the role that small pelagics (sardines, mackerel, anchovies, etc.) could still play in human health and food safety in the context of climate change. The decline in the nutritional quality of small pelagic fish (SPF), particularly sardines, the leading product in French tinned food consumption and known for its nutritional properties (omega3), is now a source of concern for scientists and the industry, even if it is not yet perceptible to consumers.

We are interested in how the sardine industry in France deals with these changes in order to build its differentiation strategies based on food values (Lusk & Briggeman (2009)) that are supposed to reflect the heterogeneity of consumer preferences in this mature market. To do so, we grouped the claims identified on a representative sample of 1,442 tins of sardines sold in super and hypermarkets into 11 Food Values (FV: Old, Taste, Origin, Tradition, Omega, Health, Sustainable, Organic, Convenience, Premium, Equity). Next, an econometric model of hedonic prices was estimated with the FV and other attributes (sales location, brands,...) to explain the average effects of the attributes on the price of tins. Then, given the heterogeneity of observed prices, quantile regressions (deciles) representing different market segments are also performed.

The main results show the positive and significant effect of the number of claims on prices, reflecting a strategy of horizontal differentiation. To analyse this strategy, we look in greater detail at the effect of FVs on price. We show that Health and Omega VFs, specific and intrinsic attributes of sardines, are used to attract price-sensitive customers. Indeed, FV Omega reduces tin prices in the low-price segment, and FV health has a similar effect in the mid- and high-end segments. By contrast, Sustainable FV leads to higher prices in all market segments, but the higher the range, the lower the price. FV Old means higher prices for entry-level tins and lower prices for top-of-the-range tins. FV taste and origin have a robust positive impact across all segments.

Finally, our findings show that the presence of omega 3 in sardines is likely to attract a very wide range of consumers. If sardines lose their nutritional value, consumers looking for low-priced products with high nutritional value are likely to turn away from this market, with food safety implications.

Seafood, one of the most highly traded commodities, benefits diverse livelihoods and supports global nutrition by supplying critical fatty acids, micronutrients, and animal protein. Additionally to providing nutrients, seafood production can be sustainable, having low greenhouse gas emissions similar to plant-based foods. Seafood is highly-traded, with around ⅓ of fishery production exported and with seafood demand varying geographically, seafood trade and consumption are becoming increasingly globalized. Seafood trade is especially important for buffering food insecurities within equatorial regions as they are subject to nutritional deficiencies and food vulnerabilities, and many countries rely on imports for large shares of their seafood consumption. Reliance on seafood imports, however, may introduce implications for the risk of countries’ imports; imports are critical for food security as food availability tends to be higher with imports.

At the same time, catch is projected to decline in some regions under climate change, which may pose threats to countries’ import portfolios, and furthermore their food security. Climate change can lead to reductions in seafood macro- and micronutrients and may become increasingly constrained by slow moving climatic changes. Additionally moving into the future, species invasion may be the most intense around the arctic and southern oceans, limiting catch. This may impact lower income, climate vulnerable countries the most including wild capture fisheries in Africa, South and Southeast Asia, equatorial regions, and Small Island Developing States. This creates a potential vulnerability for import dependent countries, as declines in partner countries’ exports can reduce importer’s national seafood supplies, and there are currently no risk evaluations on countries’ seafood imports. We pose the overarching research question: What is the future climate risk embedded in countries’ seafood import portfolios?

To answer this research question, We will apply the Intergovernmental Panel on Climate Change vulnerability formula to compare risk across countries: Vulnerability = (Exposure + Sensitivity) - Adaptive Capacity. We are leveraging the new Aquatic Resource Trade in Species (ARTIS) database which has disaggregated global trade data by country of harvest, production method, and species, resulting in estimated consumption for over 2400 species, 193 countries, and 35 million bilateral trade records going back to 1996 as measures of sensitivity. We are also compiling social-economic variables from national data portals and future climatic variables as measures for adaptive capacity and exposure. We will present estimated national vulnerabilities of import portfolios to climate change, highlighting the regions with the highest vulnerabilities and the factors driving high vulnerability. We hypothesize that countries’ imports that are dependent on lower latitude countries while having a lower adaptive capacity will yield higher import portfolio risks (e.g., U.S with high adaptive capacity relying on imports from low latitude countries = lower risk; Liberia with low adaptive capacity relying … = higher risk). The results from this work highlight a key vulnerability in the ability of aquatic foods to contribute to nutrition security in the face of climate change and point to areas in need of adaptation strategies.
