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 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.
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.
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 Habits and the Occurrence of Anthropogenic Debris in the Stomach Content of Marine Fish from Pattani Bay, Gulf of Thailand
Researchers found anthropogenic debris in the stomachs of 12 of 34 marine fish species from the Gulf of Thailand, with planktivorous fish ingesting the most debris and blue-colored items predominating, with ingestion rates peaking during the northeast monsoon season.
Study of feeding biology and diet-associated microplastic contamination in selected creek fishes of northeastern Arabian Sea: A multi-species approach
Researchers studied the feeding biology and diet-associated microplastic contamination of selected fish species, finding that feeding habits directly influence the quantity and type of microplastics ingested. The results demonstrate that trophic position and prey preferences are key predictors of microplastic exposure in wild fish.
Use of estuarine resources by top predator fishes. How do ecological patterns affect rates of contamination by microplastics?
Researchers found that over 50% of snooks (Centropomus undecimalis and C. mexicanus) across all life stages in a tropical estuary had ingested microplastics, with contamination rates linked to seasonal shifts in habitat use and feeding ecology between estuarine and marine environments.
Changes in the food selectivity of zooplanktivorous fishes related to the effects of nutrient enrichment in an urban tropical estuary
Researchers studied juvenile fish diets in an urban tropical estuary and found that nutrient enrichment from eutrophication shifted prey availability and fish feeding strategies, while all fish species examined contained microplastic particles and showed selective ingestion of them alongside their natural zooplankton prey.
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.
Dinámica temporal de los hábitos tróficos e incidencia de microplásticos en bagres (Ariidae) en la bahía de Buenaventura, Pacífico colombiano
Four species of catfish in Colombia's Buenaventura Bay were found to have ingested microplastics, with rates of 9–13% across species and higher ingestion in adults during the rainy season. The finding that commercially harvested fish in a bay heavily used for artisanal fishing contain microplastics raises direct food safety concerns for the coastal communities that depend on these species as a primary protein source.
Microplastics in fishes in amazon riverine beaches: Influence of feeding mode and distance to urban settlements
Researchers found microplastics in the digestive tracts of 29 fish species from Amazon riverine beaches, with contamination levels influenced by fish feeding mode and distance to urban settlements within a protected area.
Plastic density as a key factor in the presence of microplastic in the gastrointestinal tract of commercial fishes from Campeche Bay, Mexico
Researchers found microplastics in 316 particles across 240 gastrointestinal tracts from six commercially consumed fish species in Campeche Bay, Mexico, with average ingestion of 1.31 MPs per fish, and found that fish feeding in mid-water column tended to ingest denser polymer types reflecting their depth distribution.
Relationship of Microplastics to Body Size for Two Estuarine Fishes
Researchers found that microplastic ingestion in hardhead catfish from the northern Gulf of Mexico increased significantly with body size, while southern flounder showed no such relationship, suggesting that feeding ecology and habitat use drive species-specific exposure patterns.
Ecología trófica y consumo incidental de microplásticos en peces (Sciaenidae) y su relación con la dinámica ambiental en la bahía de Tumaco, Pacífico colombiano
Researchers investigated the trophic ecology and incidental microplastic consumption of Sciaenidae fish from Tumaco Bay in the Colombian Pacific, conducting four sampling campaigns between 2020 and 2021 using artisanal fishing gear and examining 467 individuals. The study examined the relationship between fish feeding behavior and environmental dynamics in the bay, finding microplastics present alongside prey organisms in fish digestive systems.
Effects of microplastic ingestion on feeding activity in a widespread fish on the southwestern Atlantic coast: Ramnogaster arcuata (Clupeidae)
Researchers investigated microplastic ingestion in the widespread South Atlantic fish Ramnogaster arcuata, finding evidence that microplastic presence in the gastrointestinal tract may affect feeding activity in natural environments with varying levels of anthropogenic pressure.
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.
Intake of microplastics by fishes in a floodplain lake of the Curiaú River (Macapá, Amapá, Brazil)
Researchers examined microplastic ingestion in fish from a floodplain lake of the Curiaú River in the Brazilian Amazon, finding microplastics in stomach, intestine, and gill samples with ingestion patterns reflecting both passive and active uptake during normal feeding behavior.
Dynamics of Marine Debris Ingestion by Profitable Fishes Along The Estuarine Ecocline
Researchers found that snook fish in Brazilian estuaries accumulate microfilaments (tiny plastic threads under 5 mm) throughout their lives, with adults ingesting the most — especially during rainy season when fishing activity peaks. The color and size of ingested microfilaments matched local pollution sources, suggesting both direct consumption and trophic transfer (eating contaminated prey) are key pathways.

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.
In situ microplastic ingestion by neritic zooplankton of the central Mexican Pacific
Researchers documented in situ microplastic ingestion by zooplankton in two bays of the central Mexican Pacific, finding that copepods, decapod larvae, and chaetognaths ingested microplastics, predominantly fibers, with higher rates during the rainy season.
First evidence of microplastic ingestion by fishes from the Amazon River estuary
Researchers documented the first evidence of microplastic ingestion by fish in the Amazon River estuary, finding plastic particles — predominantly polyamide and polyethylene pellets — in 30% of 189 specimens across 14 species, with larger fish containing more particles, indicating widespread contamination extending into one of the world's most biodiverse river systems.
High intake rates of microplastics in a Western Atlantic predatory fish, and insights of a direct fishery effect
Researchers found microplastics in over half of the weakfish (Cynoscion acoupa) sampled from a tropical Brazilian estuary, with ingestion dominated by short filaments in the lower estuary and longer, less-weathered filaments in the upper estuary near river inputs. Adult fish accumulated the most plastic, particularly blue filaments consistent with fishing gear, with ingestion increasing during the late rainy season when fishing activity was highest.
