ClearMicroplastic 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.
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.
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.
Occurrence of microplastics in the gastrointestinal tract of pelagic and demersal fish from the English Channel
Researchers examined the gastrointestinal tracts of both pelagic and demersal fish species and found microplastics in individuals from both groups, suggesting that microplastic ingestion occurs across fish species regardless of their position in the water column.
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.
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.
Widespread microplastic ingestion in Colombian Caribbean marine fish: Trophic influence, spatial-temporal trends, and polymer composition
Researchers examined three commercially important fish species from the Colombian Caribbean and found microplastics in over 82% of individuals across both continental and island waters. Fiber and fragment shapes were the most common types, with higher concentrations found in coastal areas and during the wet season. The findings suggest that microplastic ingestion is widespread among Caribbean fish, with potential implications for seafood consumers in the region.
Occurrence and potential effects of plastic ingestion by pelagic and demersal fish from the North Sea and Baltic Sea
Researchers examined the occurrence and potential effects of plastic ingestion in pelagic and bottom-dwelling fish from the North Sea and Baltic Sea, finding plastics in both groups. The study contributed to baseline knowledge of microplastic ingestion rates in commercially important fish species in European seas.
Abundance and ecological risk of microplastics in commercial fish species from northeastern Mediterranean Sea
Researchers examined nine commercially important fish species from the northeastern Mediterranean Sea and found microplastics in both their digestive tracts and gills. The most common particles were small polyethylene and polypropylene fibers, and bottom-dwelling fish species had higher contamination levels. While the ecological risk was rated low to medium, the presence of microplastics in widely consumed fish species highlights a potential pathway for human exposure through seafood.
Ingestion of microplastics by pelagic fish from the Moroccan Central Atlantic coast
Researchers found microplastics in the stomachs of three small pelagic fish species caught along the Moroccan Central Atlantic coast, confirming plastic ingestion in commercially important species in a region where marine litter is predominantly plastic. The study adds to growing evidence of microplastic contamination in North African Atlantic fisheries.
Microplastic ingestion and diet composition of planktivorous fish
This study analyzed stomach contents of six planktivorous pelagic fish species from Atlanto-Iberian waters, finding microplastics in a substantial proportion of individuals. The relationship between microplastic ingestion and diet composition suggests that fish consuming prey similar in size to microplastics are at higher risk of ingestion.
Using Boops boops (osteichthyes) to assess microplastic ingestion in the Mediterranean Sea
Researchers assessed microplastic ingestion in 884 Boops boops fish caught at 20 coastal sites across Spain, France, Italy, and Greece, finding microplastics in 46.8% of individuals with an average of 1.17 items per fish, predominantly filaments composed of polyethylene and polypropylene.
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.
Occurrence of microplastics in commercial fish from a natural estuarine environment
Researchers examined the gastrointestinal tracts of commercial fish caught from a natural estuarine environment and found microplastics in a significant proportion of individuals, documenting both occurrence rates and particle characteristics.
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.
Characteristics and retention of microplastics in the digestive tracts of fish from the Yellow Sea
Researchers systematically characterized microplastics in 19 fish species from the Yellow Sea coast of China, finding plastic retention in 34% of individual fish sampled, with fibers dominating and significant variation in microplastic load by species and habitat.
Occurrence of microplastics in the gastrointestinal tracts of some edible fish species along the Turkish coast
Researchers examined the gastrointestinal tracts of 243 individual fish from five edible species along the Turkish coast, documenting the occurrence and characteristics of ingested microplastics. The study found microplastics present in multiple commercially important fish species, raising implications for seafood safety and human dietary exposure.
Plastic density as a key factor in the presence of microplastic in the gastrointestinal tract of commercial fishes from Campeche Bay, Mexico
Researchers found microplastics in 316 particles across 240 gastrointestinal tracts from six commercially consumed fish species in Campeche Bay, Mexico, with average ingestion of 1.31 MPs per fish, and found that fish feeding in mid-water column tended to ingest denser polymer types reflecting their depth distribution.
A meta-analysis of the characterisations of plastic ingested by fish globally
This meta-analysis pools data from global studies to assess what types of plastic fish most commonly ingest, finding that microfibers and small fragments dominate across both freshwater and marine species. These findings are important for human health because widespread plastic ingestion by fish means that microplastics are likely present in much of the seafood consumed around the world.
Plastic ingestion by pelagic and demersal fish from the North Sea and Baltic Sea
Researchers examined gastrointestinal tracts of 290 North and Baltic Sea fish and detected plastic in 5.5% of individuals, with pelagic species like herring and mackerel ingesting plastic at three times the rate of bottom-dwelling cod and flounder, and polyethylene making up nearly 40% of identified polymer types.
Microplastic Characteristic Found in Gastrointestinal Tract of Pelagic and Demersal Fishes in Tuban, East Java
Researchers found microplastics in the gastrointestinal tracts of both pelagic and demersal fish species, documenting plastic ingestion across different feeding guilds and ocean depths. The study adds to growing evidence of widespread microplastic contamination throughout marine food webs.
