Investigating Consumer Attitudes and Market Trading of Edible Marine Invasive Alien Species in the Greek Seafood Market

Marine invasive alien species (IAS) are spreading in the Mediterranean Sea, altering species composition and reshaping marine ecosystems. The study explores consumer attitudes towards the consumption of marine invasive alien species (IAS), particularly lionfish and Atlantic blue crab, in the Greek seafood market. These species are considered a threat to marine biodiversity but are also being considered for commercial seafood to mitigate their ecological impact. Through surveys of consumers and seafood retailers, the research finds that while Greek consumers show a positive attitude towards consuming these species, they often lack awareness of their ecological impact. Retailers see potential in promoting these invasive species, with freshness, hygiene, and poison concerns being the most important factors for consumers when purchasing seafood. In general, there is a need for better public education regarding the ecological and health impacts of IAS consumption. Factors that could increase consumption include recommendations from seafood retailers, promotion by TV cooking shows, and quality certifications. The study suggests that aligning consumer education with conservation goals could help control the spread of IAS while supporting local fisheries.
