The Sustainability of Seafood Products in the Opinions of Italian Consumers of Generation Z.

This study aims to explore whether members of Generation Z have sensitivity and awareness about environmental issues related to seafood production and consumption, their beliefs on how to make more sustainable the future provisioning of seafood, their consumption frequency, and, finally, whether different profiles and groups of people could be detected. A survey was implemented with 778 Italian students attending secondary schools. Descriptive statistics, testing, and cluster analyses were applied. Results provide the sustainability profile of five groups, of which three are aligned with SDGs 12 and 14, but the other groups, comprising almost half of the sample, are insensitive, unaware, or irresolute about the sustainability of seafood production and consumption. Overall, people's environmental consciousness does not appear to be strongly related to the frequency of consumption of sustainable seafood species. Regarding the solutions for improving the sustainability of future seafood production, young respondents underlined the catching and raising of novel, discarded, not exploited, or marginally exploited seafood species. People declared a high knowledge of the nutritional and safety implications of seafood. This study is one of the few that explore issues specifically related to the profiles of Generation Z and young people's approach toward sustainable seafood production and consumption.

Assessing high school students' perceptions and preferences for aquaculture versus wild‐caught seafood: The case of Oʻahu, Hawaiʻi

AbstractAn increasing population and demand for seafood have provoked a need to understand the factors affecting consumers' perceptions of aquaculture and wild‐caught seafood to ensure the sustainability of ocean resources. A survey was developed to assess Hawaiʻi's high school students' perceptions and preference for aquaculture and wild‐caught seafood using a cognitive mapping framework. The survey was administered to three high schools across urban, suburban, and rural areas of the island of Oʻahu, Hawaiʻi. Using descriptive statistics, analysis of variance (ANOVA) tests, and mental modeling techniques the following results from the survey indicated that most students had some knowledge of aquaculture. Residence and gender demographics of students make a difference in their preference for aquaculture and wild‐caught seafood. Overall, the students indicated a higher preference for wild‐caught seafood as compared to aquaculture in terms of taste and the reverse is true for environmental impacts. However, rural residents and male students showed a significant preference for aquaculture seafood. The implications of this study provide the information needed to improve public perceptions of aquaculture and promote sustainable seafood practices and consumption. Furthermore, education focused on aquaculture can be introduced into school curricula to enhance their knowledge of environmental, health, and nutrition impacts.

NGO and Global Voluntary Standards in Sustainable Seafood: The Case of Aquaculture Stewardship Council (ASC) in Indonesia

This article examines the role of non-governmental organisation in supporting the implementation of global voluntary certification. This article investigates how World Wildlife Fund (WWF) helps implement the Aquaculture Stewardship Council (ASC) ecolabel standard in Indonesia. As the world’s second-largest aquaculture fish-producing country, many Indonesian seafood products are rejected in the international market due to quality problems. This makes Indonesia an ideal country for implementing sustainable aquaculture practices. Using transition theory as a framework, we find that WWF has played a key role in three areas: (1) harmonisation of national regulations with ASC principles, (2) establishment of a campaign program to advocate for the public on sustainable seafood consumption behaviour, and (3) creating a special agency to assist to fishery industry players in obtaining ASC certificates. Our finding sheds lights on the importance of strong collaboration between business actors, states, and non-governmental organisations (NGOs) to implement global voluntary standards.

Tasting the ocean: How to increase ocean literacy using seafood heritage with a visceral approach

This contribution explores the growing interest in ocean literacy and sustainable seafood consumption through the lens of transdisciplinary and visceral research methods. It illustrates a series of experimental, marine-focused workshops, carried out during the Covid-19 pandemic for Irish students aged between 15 and 18. The empirical body builds on a series of questionnaires completed prior, during and at the end of the workshops as well as direct observations of feedbacks and interactions. By offering to the students creative and playful methods which included cooking classes, coastal explorations and information about their coastal cultural heritage, we argue that transdisciplinary and visceral methods can facilitate how ocean literacy and sustainable eating is understood and operationalised—in both educational programmes and policy frameworks.

Seafood Sustainability Supply Chain Trends and Challenges in Japan: Marine Stewardship Council Fisheries and Chain of Custody Certificates

In Japan, fisheries’ product has decreased since the 1980s, and the government amended the fisheries law in 2020 to shift to managed fisheries. However, awareness of seafood sustainability is still low. This study identifies the reason for the low awareness and states the necessary actions to increase sustainable seafood consumption. The proactive stakeholders in seafood supply were surveyed to determine the current status of sustainable seafood sales. Marine Stewardship Council-certified fishers and MSC’s Chain-of-Custody certification holders answered the questionnaires. Fishers showed a positive attitude, citing proactive sales channel expansions and contributions to sustainability. Distributors were primarily passive, mainly because they obtained the certification at the request of their clients, and about half of them did not disseminate information between consumers and suppliers. Both fishers and distributors expect the government to promote campaigns and education. The stages of the awareness of producers, intermediary trade, and retailers are different and did not align. Therefore, if the supply chain stakeholders proactively educate themselves, choose sustainable products from the fishers, and pass the sustainability information to the consumers, sustainable seafood consumption would progress.

Evaluating the Feasibility of Sustainable Seafood Labelling Programmes in Small Island Developing States: A Pilot Study of Artisanal Fisheries in Seychelles

The Republic of Seychelles is one of six African Small Island Developing States (SIDS) and has a marine-based economy reliant on fisheries and international tourism. Seychelles has been flagged by the United Nations as highly vulnerable to climate change. Climatic threats are compounded with population declines of key fishery species. A progressive national stance towards ocean sustainability and an emerging economy partially driven by tourists are two of several factors that make Seychelles a good candidate for a sustainable seafood labelling and consumption programme, which would provide market-based incentives for fishery harvesters, regulators, buyers and consumers to improve sustainable practices. To address the feasibility of such a programme, we conducted a pilot study, surveying 33 artisanal fishers and mapping supply chain structure to examine incentives and challenges. Questions addressed fishers’ years of experience, reliance on fishing for income, and flexibility in gear type and species targeted. Of the total number of respondents, 64% would like to see a programme implemented but only 34% thought it would be successful. Participants identified several barriers and benefits that primarily spanned socioeconomic and regulatory themes. Our pilot results indicate the sociocultural and economic impacts of sustainability programmes in Seychelles are as important as environmental considerations, a finding pertinent to anyone undertaking similar research efforts in other SIDS. We advocate for the necessity of thorough, location-based research and in-depth stakeholder consultation to elucidate economic, societal, behavioural and cultural factors that will affect the success of designing and implementing seafood labelling programmes in SIDS.

Sustainable Seafood Consumption in Action: Reinvigorating Consumers’ Right to Information in a Borderless Digital World

ABSTRACT Sustainable consumption is a core pillar to give effect to Goal 12 of the 2030 Agenda for Sustainable Development adopted by the United Nations in 2015. This article identifies consumers’ right to information as a legal conduit to integrate consumer interests with those of industry and regulatory stakeholders through globalized and digitized supply chains. Drawing on the momentum for integration in global fisheries management, the article studies the rise and proliferation of transnational governance models for information to secure legal and sustainable seafood supplies. It critically evaluates the reasons for and consequences of less-than-full engagement and legal protection of consumers in major seafood retail markets, including the European Union and the USA. Their existing seafood traceability systems fail to make sufficient information available to consumers, despite the ability to trace imported seafood to the origin of catch. As the goal of sustainable consumption hinges on consumer choice in an increasingly borderless market, the unavoidable challenge is to enhance consumer-facing traceability and transparency.

The development of “Blue Seafood Guide,” a sustainable seafood rating program, and its implication in Japan

Marine fish stocks have declined globally over the past half-century, and raising awareness of sustainable fisheries and seafood consumption has become a critical issue. The Blue Seafood Guide was launched as Japan’s first sustainable seafood rating program in 2013 with limited fisheries' data. In 2018, an original science-based methodology was incorporated into the guide to balance scientific rigor against the data deficiencies inherent in common Japanese management practices, including a lack of sufficient output control and catch information. This paper aims to illustrate why and how the Blue Seafood Guide (BSG), Japan’s first sustainable seafood rating program, was developed to best suit Japan's insufficient data infrastructure to raise awareness around sustainable seafood consumption. Also, it explains how the BSG attempted to create a nexus between fishery certificates and rating programs. In 2020, new legislation and Japanese fisheries policy reforms led to the implementation of catch documentation and import control rules. As a result, the Japanese fishing industry is experiencing a revolutionary transition to a global standard for sustainable fisheries. The BSG focuses on the nexus of science and policy and seeks to establish collaboration between certification and rating programs to accomplish its mission of encouraging sustainable seafood consumption positively and protecting the oceans for generations to come. This paper also summarized BSG’s implementation activities for awareness rising in Japan. At the discussion, we summarize lessons learnt and demonstrate perspectives for those who intend to develop seafood rating programs in other countries or areas similar to Japan.

Enhancing Sustainable Consumption in China: A Seafood Example

Abstract In recent years, market surveys on sustainable seafood consumption have analysed Chinese people’s willingness to purchase ecolabelled seafood produced and imported into China. Endogenous and exogenous determinants are thereby unveiled to explore Chinese consumers’ sustainability consciousness, purchasing decisions, and the means of bridging the divide. This article builds upon and adds to these empirical findings with a market-based and information lens. It draws inspiration from analysing the growing interest of younger and middle-class consumers in acquiring seafood information; integrative sourcing and marketing strategies of intermediary businesses to deliver such information; and awakening of public regulators to the imperative of realizing the right to information of less-informed parties. Instead of segregating these stakeholders along a linear supply chain, the study emphasizes the deepening of a consumer-centric information network underpinned by supply chain transparency and traceability. It thus aims to inform a steady shift from a production-oriented to a consumer-oriented seafood management paradigm through systematic reforms of China’s consumer law. To encourage and empower sustainable consumption, the ‘consumer’ notion needs proper broadening and consumers’ right to know should be recognized as a judicial and self-contained legal entitlement with enforcement safeguards.

Reducing Mediterranean Seafood Footprints: The role of consumer attitudes

Seafood is central to the diet of Mediterranean inhabitants. However, there is high consumer demand for certain species whose populations are rapidly declining in the Mediterranean Sea. Diversifying regional seafood preferences has the potential to reduce pressure on marine ecosystems while supporting local fishing economies. Here, we explored this opportunity through case studies in three Mediterranean countries: Croatia, Italy, and Turkey. First, we conducted an Ecological Footprint Analysis (EFA) to quantify the environmental impact of each country's food consumption choices. Then, we distributed a seafood consumer survey to understand each country's dietary preferences and residents' overall willingness to change their diets, with a specific focus on products from Small-Scale Fisheries (SSF). We found food consumption to be the primary Ecological Footprint driver in all three countries, with a contribution from the consumption of fish and seafood ranging from 6% (Turkey) to 11% (Italy) of each country's food Footprint. Results from the consumer survey showed that dietary preferences were unique to each culture. For example, consumers in Italy and Turkey were more willing to modify their diets than residents surveyed in Croatia. Across all three countries, consumers who are more aware of product labels, origin, and freshness of seafood products were more willing to purchase diverse seafood products. To diversify seafood consumption choices, particularly away from high trophic level species, consumer awareness campaigns should be tailored to meet the preferences of each unique culture in the Mediterranean. A broader Pan-Mediterranean study of culturally-unique consumer attitudes is warranted to accelerate progress towards sustainable seafood consumption in the region that benefits both biodiversity and local fishing economies.

Fraud in highly appreciated fish detected from DNA in Europe may undermine the Development Goal of sustainable fishing in Africa

Despite high effort for food traceability to ensure safe and sustainable consumption, mislabeling persists on seafood markets. Determining what drives deliberate fraud is necessary to improve food authenticity and sustainability. In this study, the relationship between consumer’s appreciation and fraudulent mislabeling was assessed through a combination of a survey on consumer’s preferences (N = 1608) and molecular tools applied to fish samples commercialized by European companies. We analyzed 401 samples of fish highly consumed in Europe and worldwide (i.e. tuna, hake, anchovy, and blue whiting) through PCR-amplification and sequencing of a suite of DNA markers. Results revealed low mislabeling rate (1.9%), with a higher mislabeling risk in non-recognizable products and significant mediation of fish price between consumer´s appreciation and mislabeling risk of a species. Furthermore, the use of endangered species (e.g. Thunnus thynnus), tuna juveniles for anchovy, and still not regulated Merluccius polli hake as substitutes, points towards illegal, unreported and/or unregulated fishing from African waters. These findings reveal a worrying intentional fraud that hampers the goal of sustainable seafood production and consumption, and suggest to prioritize control efforts on highly appreciated species.

The Contribution of Thai Fisheries to Sustainable Seafood Consumption: National Trends and Future Projections

Sustainably feeding a growing human population is one of the greatest food system challenges of the 21st century. Seafood plays a vital role in supporting human wellbeing, by providing bioavailable and nutrient-dense animal-source food. In Thailand, seafood demand is increasing, and wild capture fishery yields have plateaued, due to oceanic ecosystem degradation and fishery stock exploitation. In this study, we investigated the supply trend of fishery products and subsequent seafood-derived nutrient availability over the last decade. In addition, we explored the possibility of predicting seafood availability and consumption levels, including adherence to Thailand’s national food guide and global dietary recommendations for sustainable seafood consumption. Our findings indicate that, at national-level, fishery products supplied between 19% and 35% of the Thai populations recommended dietary protein intake, 4–6% of calcium, 6–11% of iron, and 2–4% of zinc from 1995 to 2015. Nevertheless, our research also reports that if Thailand’s wild-caught seafood production were to decrease by 13%, as is highly likely, by 2030, the country might face a per capita supply deficit of fish and shellfish to meet healthy and sustainable dietary recommendations (28–30 g/day), let alone the current Thai average intake (32 g/day). Although a 1% per year increase in aquaculture production might bridge this supply gap, policymakers and relevant fishery stakeholders must consider the long-term environmental impacts of such an approach in Thailand.

Mainstreaming Sustainable Consumption of Seafood Through Enhanced Mandatory Food Labeling

To contribute to the debate about sustainable seafood consumption, this article considers the role of mandatory food labeling. The article first flags the rise of a policy paradigm of shared responsibility and policy imperatives at various levels calling for increased integration of the citizen/consumer into public regimes, including in fisheries governance. It then explores the options available to citizen/consumers to engage in the fisheries regime in different stages of the value chain and evaluates their readiness to respond to the expectations. Mandatory food labeling of seafood is introduced as an under-unexplored governance tool, alongside the key enabling technological and policy trends. The rise of transparency and traceability, both as norms and a set of technological capabilities, is highlighted as an opportunity for implementation of mandatory seafood labeling. While recognizing equity challenges and various supplementary actions needed to ensure an effective behavioral and attitudinal shift toward more engaged governance (better education and enforcement and an enabling social setting), the article suggests to further explore mandatory labeling within the governance toolbox. It should be particularly relevant in the context of developed markets with global trade and political influence, and as means of fostering ocean literacy and transparent, participative and deliberative kind of governance.

FoodSmart City Dublin: A Framework for Sustainable Seafood

We propose the FoodSmart City framework as a transdisciplinary avenue to promote sustainable seafood consumption. We argue that a change in human seafood consumption towards eating at lower trophic levels may be helped by discovering forgotten cultural practices and tapping into locally-sourced marine resources. We set out a framework of knowledge exchange and production between academia, businesses, and civil society to promote and assist healthy and ecologically sustainable living using digital tools and intangible cultural heritage while engaging with innovative chefs and educationalists. The framework targets Dublin City, Ireland, but may potentially be replicated in other contexts.

Comparing importance and confidence for production and source attributes of seafood among residents and tourists in South Carolina and Florida coastal communities

The call for environmentally sustainable seafood consumption is growing. Seafood-related behavior is often an outcome of assessing attributes of the product (e.g., taste, freshness, source). To shift consumer (i.e., tourists and residents) preferences toward environmentally sustainable products, many coastal communities of the United States (U.S.) promote production (i.e., Wild-caught, Environmentally sustainable) and source (i.e., Harvested locally, Safe from pollutants) attributes of local seafood. Even if consumers believe these production and source attributes are important, they may lack confidence in their ability to distinguish them when purchasing seafood. Expansion of sustainable coastal mariculture is recommended for food security and enhancing economic resilience of local commercial fisheries, but this newer production attribute (i.e., Farmed in marine waters) adds more complexity to consumer decision-making. Research examining the difference between importance and confidence for seafood attributes is limited. This study surveyed tourists and residents in South Carolina and Florida (U.S.) coastal communities where varying levels of tourism and commercial seafood harvest, including marine farming of shellfish, were occurring. The research measured these consumers’ level of importance and confidence for production and source attributes when purchasing seafood in the coastal community. Residents rated importance and confidence higher than tourists for some attributes, but there was no difference between states for tourist or resident subgroups. Both tourists and residents rated confidence lower than importance for all attributes. An Importance-Confidence Analysis (ICA), adapted from Importance-Performance Analysis (IPA), identified attributes needing enhanced marketing and consumer education. The ICA indicated that Environmentally sustainable and Safe from pollutants were high priorities for improving confidence. The low priority rating for Farmed in marine waters was deemed misleading because improved outreach for this attribute could reduce barriers to acceptance and improve recognition.

Combined climate and nutritional performance of seafoods

National authorities in many countries advise their populations to eat more seafood, for health and sometimes for environmental purposes, but give little guidance as to what type of seafood should be consumed. The large diversity in species and production methods results in variability both in the nutritional content and in the environmental performance of seafoods. More targeted dietary advice for sustainable seafood consumption requires a better understanding of the relative nutritional benefits against environmental costs of various types of seafood. This study analyzes the combined climate and nutritional performance of seafood commonly consumed in Sweden, originating all over the world. Nutrient density scores, assessed by seven alternative methods, are combined with species- technology- and origin-specific greenhouse gas emission data for 37 types of seafood. An integrated score indicates which seafood products provide the greatest nutritional value at the lowest climate costs and hence should be promoted from this perspective. Results show that seafoods consumed in Sweden differ widely in nutritional value as well as climate impact and that the two measures are not correlated across all species. Dietary changes towards increased consumption of more seafood choices where a correlation exists (e.g. pelagic species like sprat, herring and mackerel) would benefit both health and climate. Seafoods with a higher climate impact in relation to their nutritional value (e.g. shrimp, Pangasius and plaice) should, on the other hand, not be promoted in dietary advice. The effect of individual nutrients and implications of different nutrient density scores is evaluated. This research is a first step towards modelling the joint nutritional and climate benefits of seafood as a concrete baseline for policy-making, e.g. in dietary advice. It should be followed up by modelling other species, including environmental toxins in seafood in the nutrition score, and expanding to cover other environmental aspects.

A responsible proposal for Italian seafood consumers’

Sustainable seafood consumption is a very intricate process, where different factors in diverse ways can influence the consumer’s behaviour. One of them is the knowledge on aspects related to seafood consumption and resource exploitation. Moreover, the sustainable criteria aren’t always clear and opportunely updated for consumers, both under the form of eco-labels and seafood guides. In this context, the aim of the paper was to easily provide buying suggestions based on scientific sustainable criteria, guiding consumers toward to responsible seafood consumption. Data collected during the framework of the study on consumers’ perception for eco-labeled Mediterranean anchovy, were adopted as case-study for the most common species sold in fish shop. Each species of the list of seafood preferred by consumers was synoptically related to 4 items, regarding the healthy status of the marine resource, the legal landing size, as well as biological aspects related to reproductive features. The table obtained was summarized and simplified for consumer use, realizing a friendly picture with figure/graphic, where possible. The implementation of the considered sustainable criteria provides useful suggestion orienting consumer toward to responsible seafood consumption, although a compromise among social, economic and environmental sustainability, consumer’s requests and his awareness needs to be improved.

Sustainable Seafood Consumption in Action: Relevant Behaviors and their Predictors

Within the discussion around sustainable diets, seafood consumption is still a relatively neglected field. This article discusses relevant behaviours consumers can perform to consume seafood sustainably. The predictive power of intention, descriptive social norms, trust, awareness and pro-environmental attitudes are theoretically discussed and statistically tested across two studies in regards to (a) using sustainable seafood labels, and (b) using sustainable seafood guides. Data analysis (N1 = 309, N2 = 881 Norwegian adults) shows that intentions, social norms and trust predict seafood label use across studies. The variables predicting seafood guide use are less stable which might be due to this behaviour being performed by a very small fraction of consumers only. Causal relationships have been identified in study 2 by applying cross-lagged panel analyses between intentions, trust and social norms and seafood label use. Further causal relationships were found between intentions, trust and awareness and seafood guide use. A bidirectional relationship was confirmed between descriptive social norms and seafood guide use. Potential strategies to promote seafood label- and seafood guide use, are discussed based on these results.

The Psychology of Sustainable Seafood Consumption: A Comprehensive Approach.

This paper discusses conceptual confusions of sustainable seafood consumption, practical challenges, and potential anchors from where this behaviour can be fostered. The main focus lies on psychological variables. The resulting framework comprises (1) a definition of sustainable seafood consumption, (2) suggestions for corresponding behaviours, (3) the identification of facilitating and hindering factors, (4) an assemblage of these factors into a theoretical model, and (5) a short discussion of how the model adds up value to the current state of the art in marine resource conservation. Behavioural models significantly contribute to behavioural change research. The originality and value of this research are that it tackles the so far relatively neglected field of sustainable seafood consumption as important part of sustainable development and marine conservation in the future. From an interventional perspective, the developed model facilitates the identification of contact points to approach consumers and disseminate sustainable seafood consumption among modern Western consumers.

Sustainable seafood consumption in China

Changing forms of seafood consumption in China hold immense significance for the marine ecosystems that supply this market, and are a fundamentally important challenge to address for global environmental sustainability. Drawing on recent findings from extensive ethnographic and survey research with seafood traders and consumers in China, this paper analyses policies for improving sustainable seafood consumption in China. The paper evaluates how existing policy initiatives undertaken by civil society and the government are affected by the distinctive social, economic and political context in China, and discusses how future efforts can better build on this context. To improve sustainable seafood consumption will require an effective strategy for working in a market environment characterised by a much greater public interest in food safety than food sustainability, and by a governance environment characterised by the strong role of the state.
