Ingestion of microplastics and natural fibres in Sardina pilchardus (Walbaum, 1792) and Engraulis encrasicolus (Linnaeus, 1758) along the Spanish Mediterranean coast
Microplastics and natural fibers were found in the digestive tracts of European sardines and anchovies collected from 14 stations along the Spanish Mediterranean coast, with microplastics present in about 15% of individuals. The study documents widespread but variable microplastic ingestion in two commercially important small pelagic fish species that are key components of Mediterranean food webs and human diets.
Relationship between biological, ecological parameters and microplastic concentration in Mediterranean fish species
Researchers detected and characterized microplastics in five commercially important Mediterranean fish species -- including Mullus barbatus, Sardina pilchardus, and Trachinus draco -- and analyzed how biological parameters (length, weight) and ecological factors (diet, habitat) influenced microplastic contamination levels across species.
Marine litter in stomach content of small pelagic fishes from the Adriatic Sea: sardines (Sardina pilchardus) and anchovies (Engraulis encrasicolus)
Researchers examined marine litter and microplastics in the stomach contents of sardines (Sardina pilchardus) and anchovies (Engraulis encrasicolus) from the Adriatic Sea across seasons in 2013-2014, finding marine litter in over 90% of samples from both species. Ingestion levels were correlated with species, season, and fish biometry, underscoring the widespread contamination of small pelagic fish at the base of Mediterranean food webs.
Plastics occurrence in juveniles of Engraulis encrasicolus and Sardina pilchardus in the Southern Tyrrhenian Sea
Researchers detected plastics on the external surface and in the gastrointestinal tracts of juvenile sardines and anchovies from the Southern Tyrrhenian Sea, with sardines showing higher average counts (0.53 items per fish) than anchovies (0.26 items per fish).
Ingestion and elimination of anthropogenic fibres and microplastic fragments by the European anchovy (Engraulis encrasicolus) of the NW Mediterranean Sea
Researchers found that 30–40% of European anchovies in the Ligurian Sea had ingested anthropogenic microparticles, primarily plastic fibers and fragments, with most fish containing only a single particle — suggesting relatively short retention times in the gut. The study found that larger plastic fragments may become trapped in the intestinal lumen, raising concerns about how long plastics and their associated toxins remain in commercially harvested fish.
Research and characterization of fibrous microplastics and natural microfibers in pelagic and benthic fish species of commercial interest
Researchers assessed microfiber contamination in European anchovy and red mullet, two commercially important Mediterranean fish species. The study found microfibers in 53% of anchovies and 60% of red mullet, with an average of 6.9 and 9.2 microfibers per individual, respectively, composed of polymers including cellulose, cotton, and polyester. These findings confirm that fibrous microplastics are widespread in both pelagic and deep-sea food webs, with potential implications for seafood consumers.
Ingestion of microplastics and occurrence of parasite association in Mediterranean anchovy and sardine
Scientists quantified microplastic ingestion in European sardines and anchovies from the Northwestern Mediterranean, finding 58–60% occurrence rates and noting that parasite infection was negatively associated with microplastic presence, suggesting shared ecological or physiological factors.
Ingestion of microplastics by demersal fish from the Spanish Atlantic and Mediterranean coasts
Researchers examined the gastrointestinal contents of demersal fish caught from Spanish Atlantic and Mediterranean coasts and found microplastics in a notable proportion, with fiber and fragment types most common, suggesting widespread exposure for bottom-dwelling fish.
Microplastics occurrence in edible fish species (Mullus barbatus and Merluccius merluccius) collected in three different geographical sub-areas of the Mediterranean Sea
Researchers examined the gastrointestinal tracts of 229 demersal fish from two Mediterranean species across three geographic sub-areas, finding microplastics in a significant portion of individuals with fibers as the dominant type. The study contributes to growing evidence that microplastic ingestion is widespread in commercially fished Mediterranean species.
Microplastic ingestion by pelagic and benthic fish and diet composition: A case study in the NW Iberian shelf
Researchers found microplastics in 78% of fish examined across four pelagic and benthic species from the NW Iberian shelf, with ingestion rates varying by feeding ecology and habitat depth, and identified predominantly fibers and fragments in gastrointestinal contents following alkaline tissue digestion.
Microplastic distribution in different tissues of small pelagic fish of the Northeast Atlantic Ocean
Researchers analyzed microplastic contamination in three commercially important fish species from the Atlantic coast of the Iberian Peninsula, finding plastic particles in the gut, gills, and muscle tissue. Horse mackerel had the highest contamination rates, with 92 percent of individuals containing microplastics in their digestive tract and 63 percent in their muscle. Since these fish are widely consumed by people, the presence of microplastics in edible muscle tissue is a direct concern for human dietary exposure.
Ingestion of microplastics by commercial fish off the Portuguese coast
Researchers examined the digestive tracts of commercial fish caught off the Portuguese coast and found microplastics — mainly fibers — in a substantial proportion of individuals across multiple species.
First Report of Microplastic Ingestion and Bioaccumulation in Commercially Valuable European Anchovies (Engraulis encrasicolus, Linnaeus, 1758) from the Romanian Black Sea Coast
Researchers conducted the first assessment of microplastic contamination in European anchovies from the Romanian Black Sea coast. They found that 88% of the fish contained microplastics, averaging about three plastic items per fish, which is the highest abundance reported for this species in the Black Sea. The study highlights growing concerns about microplastic accumulation in commercially important fish species and the potential for human dietary exposure.
Effect of biological and environmental factors on microplastic ingestion of commercial fish species
Researchers analyzed microplastic ingestion in commercially important fish species, evaluating how biological and environmental factors influence ingestion rates across 2,222 individual fish. The study assessed gastrointestinal tract contents to determine the extent and patterns of microplastic contamination. The findings suggest that both species-specific biology and environmental conditions play important roles in determining microplastic ingestion levels in commercial fish.
Microplastic abundance in three commercial fish from the coast of Lima, Peru
Researchers found microplastics in the stomachs and intestines of three commercially important fish species caught off the coast of Lima, Peru. The results confirm that microplastic ingestion is widespread among fish commonly consumed by humans in South American coastal communities.
Assessing the bioaccumulation of microplastics in commercially important fish species
Researchers assessed microplastic accumulation in commercially important fish species from coastal and offshore waters, finding significant differences between species based on feeding strategies and habitat depth. Filter feeders and omnivorous species accumulated more microplastics than others, reflecting diet-based differences across trophic levels. The study raises concerns about human dietary exposure to microplastics through widely consumed seafood products.
Microplastics in livers of European anchovies ( Engraulis encrasicolus , L.)
This study examined the livers of European anchovies caught in the wild and found microplastics in a subset of the organs, suggesting that plastic particles can translocate from the gut to internal tissues in commercially important fish. The finding adds to growing evidence that microplastics are not simply excreted but can accumulate in fish organs.
Microplastics in gastrointestinal tracts of Trachurus trachurus and Scomber colias from the Portuguese Coastal waters
This study found microplastics in the gastrointestinal tracts of two commercially important fish species — Atlantic horse mackerel and Atlantic chub mackerel — caught in Portuguese coastal waters, with higher incidence in one species than the other. The results confirm microplastic ingestion is common in commercially harvested fish, raising questions about human dietary exposure through seafood consumption.
