ClearFrequency of Microplastics in Mesopelagic Fishes from the Northwest Atlantic
Microplastics were found in the stomachs of mesopelagic fish collected from the Northwest Atlantic, with ingestion rates and particle types varying by species and depth. The study expands the known distribution of microplastic ingestion into deep-water fish communities, suggesting that plastic contamination has penetrated even mid-water food webs far from the surface.
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.
Synthetic and Semi-Synthetic Microplastic Ingestion by Mesopelagic Fishes From Tristan da Cunha and St Helena, South Atlantic
Scientists examined the digestive tracts of deep-sea mesopelagic fish from the remote South Atlantic and found microplastics in their intestines. The presence of plastic in fish at depths down to 1,000 meters in one of the most isolated ocean regions confirms that microplastic contamination has reached even the deep ocean.
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.
Microplastic intake in epi- and mesopelagic fish and squid species from an oceanic environment (NE Atlantic)
Researchers investigated microplastic ingestion in epi- and mesopelagic fish and squid species from the open NE Atlantic Ocean, documenting contamination in oceanic species that may confuse microplastics with similarly sized and colored planktonic prey.
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.
Occurrence of microplastics in epipelagic and mesopelagic fishes from Tuticorin, Southeast coast of India
Researchers investigated microplastic contamination in seawater and six fish species from different ocean depth habitats near Tuticorin, India. The study found microplastics in the gastrointestinal tracts of both epipelagic and mesopelagic fish, with contamination levels varying by species and habitat, suggesting that microplastic exposure extends across different marine depth zones and could affect human exposure through seafood consumption.
Microplastics Contamination of Large Pelagic Fish in the Open Atlantic Ocean
Researchers analyzed microplastic contamination in large pelagic fish including tunas, mackerels, and amberjacks collected from the open Atlantic Ocean to assess plastic exposure in top predators. They found microplastics present in fish from even remote open-ocean habitats, demonstrating the ubiquity of microplastic contamination and the utility of large migratory fish as indicators of ocean health.
Microplastic contamination in large migratory fishes collected in the open Atlantic Ocean
Researchers found microplastic contamination in large migratory fish collected during a circumnavigation of the Atlantic Ocean, with all seven commercially important species containing microplastics predominantly as fibers in their gastrointestinal tracts.
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 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 contamination in the gastrointestinal tract of some species of caught fish from Oman Sea
Researchers found microplastics in the gastrointestinal tracts of fish species sampled from marine environments, documenting plastic ingestion across multiple species. The study contributes to the growing evidence base on microplastic contamination in commercially important fish.
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.
Occurrence of microplastics in the gastrointestinal tract of benthic by–catches from an eastern Mediterranean deep–sea environment
Microplastics were found in the gastrointestinal tracts of eight deep-sea fish species collected as bycatch from the eastern Mediterranean near Sardinia, including all three shark species sampled, demonstrating microplastic contamination in deep-sea ecosystems at depths down to several hundred meters.
Microplastic ingestion by deep‐pelagic crustaceans and fishes
Among 557 individual deep-pelagic crustaceans and fishes from the Gulf of Mexico, 29% of crustaceans and 26% of fishes had ingested microplastics, with ingestion rates in non-migratory fishes increasing with depth and reaching 40% at 1200-1500 m, suggesting plastic accumulates at greater ocean depths.
Microplastic interactions with North Atlantic mesopelagic fish
Researchers examined mesopelagic fish from the North Atlantic and found microplastics in a significant proportion of individuals, with plastic loads reflecting the fish's diel vertical migration behavior. Because mesopelagic fish migrate daily between deep and surface waters, they may serve as a biological pump transporting microplastics from surface accumulation zones to depth.
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.
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.
Microplastic occurrence in deep-sea fish species Alepocephalus bairdii and Coryphaenoides rupestris from the Porcupine Bank (North Atlantic)
Microplastics were found in two deep-sea fish species collected from the Porcupine Bank in the North Atlantic, with occurrence in Alepocephalus bairdii and Coryphaenoides rupestris confirming that plastic ingestion extends to deep-water environments far from human activity. The study highlights the need for broader assessment of microplastic exposure in commercially unexploited deep-sea fauna.
Exploring microplastic ingestion by three deep-water elasmobranch species: A case study from the Tyrrhenian Sea
Researchers found microplastics in the digestive tracts of three deep-water elasmobranch species (Galeus melastomus, Scyliorhinus canicula, and Etmopterus spinax) from the Tyrrhenian Sea, with no significant differences in microplastic abundance between stomach and intestine contents across species.
