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.

Automated summary

Seafood plays a central role in the diet of Mediterranean inhabitants, but the populations of certain species are rapidly declining. By diversifying seafood preferences, it is possible to reduce pressure on marine ecosystems and support local fishing economies. Through consumer surveys and analysis, it was found that food consumption is a major driver of ecological footprints in the region, with potential for positive change through awareness and tailored campaigns.
