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.
River barriers affect river dynamics and aquatic biota, altering the entire ecosystem. Nevertheless, dams and reservoirs provide goods like water supply and low-carbon energy that are becoming increasingly critical under current climate change. To know to what extent dams and reservoirs are important to the population, we explored social attitudes towards dams and reservoirs using a face-to-face questionnaire in two regions of contrasting climate and water security in Spain, a country with one of highest densities of dams in Europe. Results (N = 613) revealed a higher support for dams, mediated by the recognition of the services they provide, in the drier Mediterranean Malaga province (Andalusia), than in the wetter Atlantic Asturias province (Bay of Biscay), where water shortages are rare. Awareness of the impacts of the dams was more pronounced in Malaga, coupled with a higher willingness to pay for reconnecting rivers. Social awareness of both impacts and services provided by dams and reservoirs may depend on local climate and water security; different dam acceptance emphasizes the need to involve local citizens in the decision-making processes about water management.

Oceans provide a wide range of ecosystem services, including food and cultural ecosystem services derived from fisheries. The sustainability of fisheries is addressed by United Nations Sustainable Development Goal 14 on ocean conservation, and education strategies should include ways to achieve it. In this paper, we describe a game-based learning environmental education experience for the promotion of artisanal fishing developed in northwest Spain, in which more than a thousand primary education students (aged 6–12) participated. Following a qualitative methodology, we analyze our own generated games, their formative assessment, and the results of their implementation in schools and informal education events. Moreover, we compare the educational games generated with other game-based learning experiences on ocean literacy and the sustainability of fisheries. These educational experiences provide play-based learning opportunities in which students show great motivation and increase their knowledge about marine biodiversity, the socio-environmental effects of fisheries, and ocean conservation. Some differences were identifiable in the choice and design of the games, including their type and duration, the dimensions of sustainability analyzed, the specific learning objectives sought, the historical and cultural references used, cooperative peer learning, and the generation of shared knowledge. In this experience, the inclusion of education for responsible consumption (SDG 12) within the sustainability of fisheries represents a remarkable innovation, empowering students in their role as fish consumers.
