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.
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.
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.
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.
First insight into plastics ingestion by fish in the Gulf of California, Mexico
Researchers found that 50% of 1,095 fish examined from 13 species in a tropical estuarine system in the Gulf of California had ingested plastic particles, with all recovered particles being threads and most being small microplastic fibres.
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 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.
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.
Microplastic in the stomachs of open-ocean and deep-sea fishes of the North-East Atlantic
Researchers investigated microplastic occurrence in the stomachs of 390 fish from three pelagic and two deep-sea species in the North-East Atlantic, comparing plastic ingestion between fish occupying contrasting ocean compartments. The study documented microplastic presence across species at different depths, highlighting how plastic contamination extends throughout the oceanic water column.
Comparative study of microplastic ingestion in commercial fish species from macaronesia
Researchers analyzed the gastrointestinal contents of 634 fish from seven commercial species across all four Macaronesian archipelagos to compare microplastic ingestion rates by species, habitat, and feeding behavior. They found microplastics across all species and locations, with ingestion rates varying by species ecology, contributing baseline contamination data for commercially important fish in this Atlantic island region.
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.
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.
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.
Microplastics in Morocco's most consumed fisheries: Chemical characterization, ecological traits, and implications for human health
Researchers analyzed 240 fish from 12 of Morocco's most commonly consumed species and found microplastics in 100% of samples, with particles detected in the gills, gonads, and digestive tracts. The most common plastics were polyethylene, PET, and polypropylene, predominantly appearing as fragments and fibers smaller than 1 mm. The findings raise concerns about human exposure to microplastics and associated heavy metals through everyday seafood consumption.
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.
Does the microplastics ingestion patterns and polymer composition vary across the oceanic zones? A case study from the Indian coast
Researchers examined microplastic ingestion in 27 species of deep-sea fish from the Central Indian Ocean and found contamination in 19 of them, with PET being the most common polymer. The study suggests that feeding behavior, rather than habitat depth or trophic level, is the primary factor influencing how much microplastic deep-sea fish ingest, and proposes these fish could serve as indicators for monitoring deep-sea plastic pollution.
