ClearMicroplastics 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.
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.

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.
Microplastic occurrence in the gastrointestinal tract and gill of bioindicator fish species in the northeastern Mediterranean
Four commercial fish species from the northeastern Mediterranean were examined for microplastic presence in gastrointestinal tracts and gills, with plastics found in all species and fiber being the most common type. The results add to growing evidence that microplastic ingestion is routine for commercially harvested Mediterranean fish.
Monthly microplastics change in European anchovy's (Engraulis encrasicolus) gastrointestinal tract in the Black Sea
Researchers tracked monthly microplastic contamination in European anchovy from the Black Sea over a full year, finding seasonal variation in plastic ingestion that correlated with changes in feeding behavior and oceanographic conditions.
Microplastic uptake and gut retention time in Japanese anchovy (Engraulis japonicus) under laboratory conditions
Researchers found that adult Japanese anchovy selectively ingested 0.3-mm microplastics over 0.85-mm particles based on size but showed no color preference, and that over 90% of ingested microplastics were excreted within 20 hours, suggesting limited retention and accumulation under natural feeding conditions.
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.
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.
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.
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 by anchovies from east Lombok Harbour, Lombok Island, Indonesia
Researchers investigated microplastic contamination in the digestive tracts of anchovies (Stolephorus spp.) from East Lombok Harbour, Indonesia, finding an average of 88 microplastic particles per individual. Fibres (51%) and films (30%) dominated the microplastic morphologies, with FTIR spectroscopy confirming polymers including polypropylene, polystyrene, and polyethylene.
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 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.
Microplastic fragments and microbeads in digestive tracts of planktivorous fish from urban coastal waters
Researchers examined the digestive tracts of 64 Japanese anchovy from Tokyo Bay and found plastic fragments in 77% of the fish, averaging about 2.3 pieces per individual. The plastics were mostly polyethylene and polypropylene fragments and microbeads smaller than 1 millimeter. The findings demonstrate that microplastic contamination is widespread in urban coastal fish populations, raising questions about potential transfer through the food chain.
