Researchers assessed textile microfiber contamination in the gastrointestinal tracts of European hake from the Tyrrhenian Sea. The study found widespread synthetic microfiber ingestion in this commercially important fish species, highlighting the extent to which microplastic pollution from synthetic textiles is entering marine 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.
First record of microplastics ingestion by European hake MERLUCCIUS MERLUCCIUS from the Tyrrhenian Sicilian coast (Central Mediterranean Sea)
Microplastics, specifically black synthetic fibers, were found in the stomachs of 46% of European hake examined from the Tyrrhenian Sea off Sicily. Since hake is a commercially important food fish, this raises concerns about human microplastic exposure through seafood consumption.
High microplastics concentration in liver is negatively associated with condition factor in the Benguela hake Merluccius polli
Researchers quantified microplastics in gills, liver, and muscle of 94 Benguela hake caught commercially off northwest Africa, finding that high liver microplastic concentrations were negatively correlated with fish body condition, suggesting physiological costs of microplastic accumulation.
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.
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.
Multispecies Assessment of Anthropogenic Particle Ingestion in a Marine Protected Area
Researchers assessed anthropogenic particle ingestion across 17 fish species and 8 invertebrate species in a Mediterranean marine protected area, finding that ingestion occurred across pelagic, demersal, and benthic habitats. The study used a multispecies ecosystem approach to link particle ingestion rates to trophic guild and habitat type.
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.
Microplastics Risk into a Three-Link Food Chain Inside European Hake
Researchers demonstrated microplastic trophic transfer through a three-link food chain inside European hake, finding microplastics in northern krill, blue whiting prey fish, and hake stomachs from the Cantabrian Sea, confirming field evidence of bioaccumulation through predator-prey relationships.
Plastic in digestive tracts and gills of cod and herring from the Baltic Sea
Researchers found plastic particles in the digestive tracts and gills of Baltic Sea cod and herring, with ingestion rates and particle types differing between the two species, indicating widespread exposure of commercially important fish to plastic pollution.
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 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.
Investigation of Microplastic Accumulation in Horse Mackerel (Trachurus mediterraneus) Caught in the Black Sea
Horse mackerel (Trachurus mediterraneus) caught from Turkish coastal waters were found to contain microplastics in their gastrointestinal tracts, with fibers and fragments the most common types. The study contributes to baseline data on microplastic contamination in commercially important Mediterranean fish species.
Plastic ingestion by Atlantic horse mackerel (Trachurus trachurus) from central Mediterranean Sea: A potential cause for endocrine disruption
Researchers examined plastic ingestion by Atlantic horse mackerel caught in the central Mediterranean, finding plastics in a substantial fraction of fish stomachs and identifying chemicals with known endocrine-disrupting properties in the ingested plastic types, raising concerns for both fish health and seafood safety.
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.
Trophic niche influences ingestion of micro- and mesoplastics in pelagic and demersal fish from the Western Mediterranean Sea
Stable isotope analysis of eight Mediterranean fish species found that fish with wider isotopic niches and higher trophic diversity ingested more micro- and mesoplastics, with zooplanktivorous and benthopelagic species ingesting more particles per individual than benthivorous or demersal 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.
First evidence of in vitro cytotoxic effects of marine microlitter on Merluccius merluccius and Mullus barbatus, two Mediterranean commercial fish species
This study exposed primary cell cultures from Mediterranean commercial fish — European hake and red mullet — to real marine microlitter collected from coastal waters, finding cytotoxic effects in immune and mucosal tissues. Importantly, both fish species had ingested plastics including HDPE and polypropylene, providing evidence that environmental (not just laboratory) microplastic contamination harms marine food fish.
