ClearMicroplastics in Commercially Important Small Pelagic Fish Species From South Africa
Researchers found microplastics in three commercially important small pelagic fish species from South African waters, with South African sardines showing the highest mean concentration at 1.58 items per individual. Microfibres accounted for 80% of ingested microplastics across all three species, with polyethylene-propylene-diene copolymer among the dominant polymers detected.
Occurrence of microplastics in Antarctic fishes: Abundance, size, shape, and polymer composition
Researchers examined four species of Antarctic fish and found microplastics in all of them, with fibers being the most common shape and polypropylene, polyamide, and polyethylene the most common types. Even in one of the most remote regions on Earth, fish are ingesting plastic particles that come from common household materials. This study demonstrates that microplastic contamination has reached every corner of the planet's oceans.

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.

Six commercially important fish species from coastal and oceanic habitats in central Chile were analyzed for microplastics, with red microfibers (70–100% of particles) as the dominant form and polyester, PE, and PET as the main polymers, and coastal species showing higher abundance and larger fibers than oceanic species. The study documents microplastic contamination in Chilean commercial fisheries and a habitat-dependent difference in plastic burden.
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.
Microplastic occurrence in 21 coastal marine fish species from fishing communities on Viti Levu, Fiji
Researchers analyzed microplastic ingestion in 184 fish from 21 species across three coastal communities in Fiji and found microplastics in 74% of fish examined. Fibers were the most common particle type at 66%, with polyethylene and polypropylene the dominant polymers. This dataset, the largest of its kind for Fiji, establishes a critical baseline for monitoring plastic pollution in the region's coastal fishing grounds.
Assessing microplastic abundances in freshwater fishes in a subtropical African reservoir
Scientists examined freshwater fish from a reservoir in South Africa and found microplastics in nearly 87% of the fish across eight species. Fibers were the most common type of microplastic, found in both the gills and digestive tracts of the fish. Since these fish are consumed by local communities, the widespread contamination raises concerns about human exposure to microplastics through freshwater fish, an understudied area compared to marine seafood.
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.
Low abundance of microplastics in commercially caught fish across southern Australia
Researchers examined microplastic contamination in nine commercially important fish species purchased from seafood markets across 4,000 km of southern Australia. They found that about 35.5% of fish had at least one microplastic particle in their gastrointestinal tract, with an average load of 0.94 pieces per fish, and polyolefin was the dominant polymer type. While microplastic ingestion was widespread across species and locations, the levels were lower than those reported in similar global studies.
Quantification, identification, and chemical characterization of microplastics (MPs) in commercial fishes from the Palk Strait, Southeast India
Researchers examined microplastics in the tissues and guts of 75 commercially important fish from the Palk Strait in Southeast India, finding an average of 115 particles per individual. Fibers were the most common form at 51%, with polyethylene and polypropylene as the dominant polymers, and particle sizes ranged from 0.1 to 1.0 millimeters. The presence of microplastics in edible fish tissues suggests a potential route of human exposure through seafood consumption.
