Worldwide contamination of fish with microplastics: A brief global overview
A literature review from March 2019 to March 2020 synthesized worldwide data on microplastic contamination in fish, finding that a median of 60% of fish from 198 species across 24 countries contained microplastics in their organs. Carnivorous species ingested more microplastics than herbivores, consistent with trophic transfer and bioaccumulation through food webs.
A global synthesis of microplastic contamination in wild fish species: Challenges for conservation, implications for sustainability of wild fish stocks and future directions
Researchers conducted a global synthesis analyzing 260 field studies covering over 1,000 fish species and found that microplastics have been recorded in 830 wild fish species, including 606 species important to commercial fisheries. Among the affected species, 34 are classified as globally threatened on the IUCN Red List. The study highlights that microplastic contamination is widespread across wild fish populations, with implications for both conservation and food safety.
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.
Microplastics in Fish: A Comprehensive Review
This review synthesizes research on microplastics in fish, covering contamination sources, detection methods, and impacts on wild and farmed populations globally — and examining how plastic particles in fish tissues may transfer to humans through seafood consumption.
What are the global patterns of microplastic ingestion by fish? A scientometric review
This review summarizes global research on microplastic ingestion by fish and finds that contamination is widespread across aquatic ecosystems, with fibers and fragments being the most commonly ingested shapes. The study highlights that fish higher on the food chain tend to accumulate more microplastics, which matters for human health since many of these species are commonly consumed as seafood.
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.
Microplastic contamination in wild freshwater fish: Global trends, challenges and perspectives
This global review analyzed 144 studies on microplastic contamination in wild freshwater fish across 45 countries and found that 450 fish species were contaminated, including 35 species on the conservation Red List. Microplastics were most commonly found in the gastrointestinal tract, with fibers and fragments being the dominant shapes. The evidence indicates that freshwater fish worldwide are widely exposed to microplastic pollution, with potential implications for both aquatic ecosystems and human seafood consumption.
Occurrence of microplastics (MPs) in the gastrointestinal tract of fishes: A global systematic review and meta-analysis and meta-regression
Fish globally averaged 2.76 microplastic particles per gastrointestinal tract, with fish from enclosed water bodies (lakes, estuaries) containing 2-4x more than those from open oceans, and fish from low-income economies harboring 5.5x more microplastics than those from high-income economies.
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.
Global meta‐analysis reveals diverse effects of microplastics on freshwater and marine fishes
This systematic review and meta-analysis examines the effects of microplastics on fish in both freshwater and ocean environments. The findings show that microplastics reduce feeding, impair digestion, slow growth, and weaken immune function in fish, which is concerning because contaminated fish are a major food source for people worldwide.
Plastic ingestion by marine fish is widespread and increasing
Researchers compiled data from studies covering over 171,000 individual fish across 555 species and found that plastic ingestion by marine fish is widespread and increasing over time. A total of 386 species were documented to have ingested plastic debris, including 210 commercially important species. The study suggests that as plastic pollution grows, the proportion of marine fish species affected by plastic ingestion will continue to rise globally.
Comparative study of microplastic ingestion in commercial fish species from macaronesia
Researchers analyzed microplastic ingestion in 634 fish from seven commercially important species across all four Macaronesian archipelagos, comparing abundance and characteristics of ingested particles across species with different habitats, feeding behaviors, and geographic distributions.
Global Review and Analysis of the Presence of Microplastics in Fish
This global review and meta-analysis compiled data on microplastic occurrence in fish from studies across dozens of countries, finding microplastics in fish from virtually all sampled regions with higher concentrations in coastal and urban-influenced waters. The analysis identified fibers and fragments as the most common forms, and raised concerns about human dietary exposure through fish consumption.
Occurrence, distribution and characteristics of microplastics in gastrointestinal tract and gills of commercial marine fish from Malaysia
Researchers examined 158 commercial marine fish from 16 species in Malaysia and found microplastics in the gastrointestinal tracts and gills of all species studied. Fibers were the most common microplastic type, and the contamination levels varied between sampling locations. The findings add to growing evidence that microplastics are widespread in commercially important fish species, raising questions about the potential for human exposure through seafood consumption.
