- Purpose – Portugal is a country with one of the highest seafood consumption per capita in the world. The purpose of this paper is to understand the Portuguese knowledge and attitudes towards seafood and relate it to consumers’ environmental conscious. Design/methodology/approach – Using an internet-based survey the authors investigated the relation of socio-demographic variables to consumption frequency and how knowledge about seafood is associated with interest in different information when purchasing seafood products. Findings – Results demonstrate consumption of a high diversity of species. Tuna and cod are the top species related to convenience and food traditions. There is a preference to consume seafood mostly at home and prepared grilled. Differences between higher and lower knowledgeable consumers’ related to seafood, show that the first ones have a more diversified use of species and high prevalence of small pelagic fish. Research limitations/implications – The findings are influenced by the sample obtained, which overrepresents well-educated and higher income people. Moreover the self-reported consumption can be biased by individuals own perceptions and different seafood products. Better estimations of consumption frequency could result from asking more detailed information, as such as by species or meal occasions. Practical implications – Portuguese consumers have high knowledge about seafood but it is not necessarily related to sustainable choices. To help in sustainable seafood choices it might be more effective to promote existing habits based on Portuguese traditions that still are good alternatives for the marine environment. Originality/value – A higher consumer’s knowledge does not necessarily mean more sustainability

- This study aims to assess the environmental impacts of canned sardines in olive oil, by considering fishing, processing, and packaging, using life cycle assessment (LCA) methodology. The case study concerns a product of a canning factory based in Portugal and packed in aluminum cans. It is the first LCA of a processed seafood product made with the traditional canning method. The production of both cans and olive oil are the most important process in the considered impact categories. The production of olives contributes to the high environmental load of olive oil, related to cultivation and harvesting phases. The production of aluminum cans is the most significant process for all impact categories, except ozone depletion potential and eutrophication potential, resulting from the high energy demand and the extraction of raw materials. To compare to other sardine products consumed in Portugal, such as frozen and fresh sardines, transport to the wholesaler and store was added. The environmental cost of canned sardines is almost seven times higher per kilogram of edible product. The main action to optimize the environmental performance of canned sardines is therefore to replace the packaging and diminish the olive oil losses as much as possible. Greenhouse gas emissions are reduced by half when plastic packaging is considered rather than aluminum. Frozen and fresh sardines represent much lower environmental impacts than canned sardines. Nevertheless, when other sardine products are not possible, it becomes feasible to use sardines for human consumption, preventing them from being wasted or used suboptimally as feed.

- Portugal has the third highest seafood consumption per capita in the world and current patterns of seafood consumption are linked to how seafood products were embodied in the Portuguese society. The objective of this research is to understand Portuguese seafood consumption's main drivers and its consequences. For that official statistics were analyzed and a literature review on seafood consumption was undertaken. Portuguese seafood consumption is characterized by a wide diversity of species and preparing modes, when compared to other countries in Europe. Cod (salted and dried), does not exist in Portuguese waters but due to several factors, such as politics, religion and tradition, became the main species in Portuguese seafood consumption, representing around 38% of the national seafood demand. Five drivers are suggested to explain why Portuguese eat so much seafood: geography, marine resources, fisheries, social forces and politics; and consequences for the environment, economy and health are discussed. Hence while most dietary recommendations advise an increase in fish consumption is not applicable to Portugal and a more sustainable seafood consumption for the future is advocated.
