ClearMicroplastics 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.
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.
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.
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 Concentration in Mediterranean Commercial Fish: A Systematic Review

A Biomarker Approach as Responses of Bioindicator Commercial Fish Species to Microplastic Ingestion: Assessing Tissue and Biochemical Relationships
Researchers assessed microplastic intake and antioxidant biomarker responses in three Mediterranean fish species, finding that microplastic ingestion correlated with oxidative stress indicators across red mullet, bogue, and anchovy populations.
Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
Researchers analyzed microplastic pollution in commercially important seafood species, characterizing particle morphology and polymer composition across species. The study found microplastics in all species sampled, with differences in contamination levels linked to feeding ecology and habitat.
Fish as a Bioindicator of Microplastic Contamination in the Mediterranean Sea: State of Knowledge
This review examines the use of fish species as bioindicators of microplastic contamination in the Mediterranean Sea. The analysis found that increasing microplastic pollution would further threaten already-stressed fishery stocks in the region. Researchers recommend prioritizing studies on the most consumed Mediterranean fish species, such as sardine, anchovy, and bluefin tuna, which have been reported to be highly contaminated by microplastics.
Microplastics assessment in Arabian Sea fishes: accumulation, characterization, and method development
Researchers assessed microplastic accumulation in Arabian Sea fish species, developing optimized digestion protocols and characterizing polymer types to trace contamination sources, finding widespread microplastic ingestion across multiple commercially important fish species.
Microplastics in fillets of Mediterranean seafood. A risk assessment study
Researchers analyzed fillets of several common Mediterranean seafood species for microplastic contamination and estimated the associated human dietary exposure. They detected microplastics in the edible tissue of all species tested, including sardines, sea bream, and mussels. The study provides risk estimates suggesting that regular seafood consumption represents a notable pathway for human microplastic ingestion.
Contamination from microplastics and other anthropogenic particles in the digestive tracts of the commercial species Engraulis encrasicolus and Sardina pilchardus
Researchers examined microplastic and anthropogenic particle contamination in the digestive tracts of European anchovies and sardines from Spanish waters, finding widespread ingestion of synthetic particles in these commercially important fish species.
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.
Evolution of the Distribution and Dynamic of Microplastic in Water and Biota: A Study Case From the Gulf of Gabes (Southern Mediterranean Sea)
Researchers found microplastics in all surface water samples and in the digestive tracts of multiple commercially important marine species in the Gulf of Gabes, Southern Mediterranean, revealing widespread contamination in a previously understudied region.
Geographical and ecological factors affect microplastic body burden in marine fish at global scale
This systematic review analyzed microplastic levels found in marine fish worldwide and identified key factors driving contamination. Fish from areas with heavy human activity contained more microplastics, and since many of these species are eaten by people, this contamination represents a direct route of human exposure through seafood.
Bioindicators for monitoring marine litter ingestion and its impacts on Mediterranean biodiversity
Researchers reviewed existing knowledge of marine litter ingestion impacts on Mediterranean biodiversity and proposed a new integrated monitoring framework using bioindicator species, identifying major knowledge gaps in understudied habitats and sub-regions while outlining a threefold approach to simultaneously measure plastic presence and its sub-lethal effects on organisms.
The influences of spatial-temporal variability and ecological drivers on microplastic in marine fish in Hong Kong
Researchers found that over 57% of marine fish in Hong Kong waters contained microplastics, with higher abundance in fish from more polluted western waters during the wet season, and that omnivorous fish ingested significantly more microplastics than carnivorous fish regardless of collection location or season.
The assessment of the bioaccumulation of microplastics in key fish species from the Bulgarian aquatory of the Black Sea
Researchers examined five commercially important fish species from the Bulgarian Black Sea coast and found microplastics in all tissue types studied. The most common particles were polyethylene and PET pellets, with sizes ranging down to 25 micrometers, indicating widespread plastic pollution in this region that could affect both fish populations and the humans who eat them.
Microplastics in commercial fish and their habitats in the important fishing ground of the Black Sea: Characteristic, concentration, and risk assessment
Researchers analyzed microplastic contamination in six commercial fish species from the Black Sea and found microplastics in all environmental areas studied, including surface water, the water column, sediments, and fish. Fibers were the most common type of microplastic found, and bottom-dwelling fish had higher contamination levels than fish living closer to the surface. Since these are commonly eaten fish species, the findings are relevant to human dietary exposure to microplastics.
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.
