Widespread microplastic ingestion by fish assemblages in tropical estuaries subjected to anthropogenic pressures
A survey of 2,233 fish from 69 species across two tropical Brazilian estuaries found microplastics in 9% of individuals, with ingestion rates linked to feeding guild, habitat use, and proximity to urban areas. The study demonstrates that microplastic ingestion is widespread even in tropical systems and is shaped by ecology rather than occurring at random.
Plastic intake does not depend on fish eating habits: Identification of microplastics in the stomach contents of fish on an urban beach in Brazil
Researchers analyzed microplastic content in the stomachs of seven fish species from an urban beach in Brazil and found that trophic guild (carnivore, omnivore, herbivore) did not predict microplastic ingestion rates, suggesting that incidental ingestion during feeding is widespread regardless of diet type.

Microplastic contamination in demersal and pelagic fish from two differently anthropized bays on the south coast of Rio de Janeiro, Brazil
Researchers investigated microplastic contamination in demersal and pelagic fish from two bays with differing levels of human impact on the south coast of Rio de Janeiro, Brazil. The study compared microplastic occurrence across fish species and sampling sites to assess how anthropisation influences microplastic exposure in coastal fish populations.
Does the trophic guild influence microplastic ingestion in nursery areas? A case study on a southwestern Atlantic mangrove-dominated estuary
Researchers analyzed microplastic ingestion in ten fish species from a mangrove-dominated estuary in Brazil's Tropical Atlantic, finding plastics in 61% of 145 specimens. Zooplanktivorous species ingested the most (averaging 2.33 MPs per individual), with polystyrene and polypropylene dominating.
Occurrence of microplastics in the gastrointestinal tract of Amazonian fish species with different feeding habits
Microplastics were found in the gastrointestinal tracts of multiple Amazonian fish species with different feeding habits from Lake Janauacá and the Anavilhanas Archipelago, with feeding strategy influencing ingestion rates—underscoring widespread microplastic contamination even in remote Amazon basin aquatic ecosystems.
Impact of contamination due to ingestion of microplastics on commercial fish in relation to their trophic habits
Researchers evaluated the ingestion of microplastics by 28 Sciaenidae and 12 Ariidae fish species from estuaries in Tumaco and Buenaventura Bay, Colombia, examining stomach contents of 1,652 specimens across high and low precipitation seasons in 2020-2021 and analyzing how trophic level and other biological characteristics influence microplastic uptake.
Feeding Ecology and Microplastic Contamination of Planktophagous Fishes in a tropical Southwestern Atlantic Estuarine Ecosystem
Feeding ecology and microplastic contamination of two planktophagous fish species (A. clupeoides and C. edentulus) were studied in a tropical Brazilian estuary, finding both species ingested microplastics—with contamination rates varying by season, body size, and estuarine position, reflecting their copepod-dominated diets.
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.
Occurrence of microplastics in commercial fish from a natural estuarine environment
Researchers examined the gastrointestinal tracts of commercial fish caught from a natural estuarine environment and found microplastics in a significant proportion of individuals, documenting both occurrence rates and particle characteristics.
Microplastics contamination in fish, water, and sediment surrounding Ubatuba beaches, Southeastern Brazil
Simultaneous analysis of microplastic contamination in fish (Atherinella brasiliensis), water, and sediment at three Ubatuba beaches in Brazil captured spatial and seasonal variations across exposed, calm, and sheltered estuary environments. The integrated approach confirmed fish ingestion of microplastics and revealed correlations between environmental presence and biotic uptake across seasons.
Occurrence and amount of microplastic ingested by fishes in watersheds of the Gulf of Mexico
Researchers quantified microplastic ingestion by fishes across several freshwater and estuarine watersheds of the Gulf of Mexico. The study documented widespread microplastic occurrence in fish from these environments, contributing important data about freshwater contamination at a time when most research had focused on marine ecosystems.
Use of resources and microplastic contamination throughout the life cycle of grunts (Haemulidae) in a tropical estuary
Juvenile grunt fish (Haemulidae) in a Brazilian tropical estuary were found to contain microplastics during their early life stages in the estuary, with contamination patterns linked to their feeding habits and habitat use. Estuaries serve as critical nursery habitats for many commercial fish species, making early-life microplastic exposure especially concerning.
