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.
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.
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.
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.
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.
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.
Foraging preferences influence microplastic ingestion by six marine fish species from the Texas Gulf Coast
Researchers analyzed 1,381 fish from six Gulf Coast species and found microplastics — predominantly fibers — in 42% of individuals, with ingestion patterns reflecting the foraging ecology of each species. The results show that diet and habitat use strongly shape a fish's exposure to microplastic pollution.
Microplastic ingestion in marine mesozooplankton species associated with functional feeding traits
This study examined microplastic ingestion in marine mesozooplankton species with different functional traits, finding that feeding mode, body size, and habitat use are key predictors of plastic uptake across zooplankton communities.
Ecological traits do not predict the uptake of microplastics by fishes in a Neotropical River
Researchers found that ecological traits such as feeding guild, habitat use, and body size do not reliably predict microplastic uptake in fish species from a Neotropical river, suggesting contamination patterns are driven more by local environmental conditions than by species-specific biology.
Is the feeding type related with the content of microplastics in intertidal fish gut?
Researchers compared microplastic ingestion across intertidal fish with different feeding strategies and found that feeding type influenced the amount of plastic found in stomachs. The study suggests that filter feeders and detritivores may ingest more microplastics than active predators, linking ecological role to plastic exposure risk.
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.
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.
Microplastic loads within riverine fishes and macroinvertebrates are not predictable from ecological or morphological characteristics
Researchers measured microplastic loads in riverine fish and macroinvertebrates and found that particle counts were not reliably predicted by species ecology or morphology, suggesting that individual variation and local environmental factors play a larger role in microplastic ingestion than feeding guild or habitat alone.
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.
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.
Influence of trophic overlaps and trophic niche amplitude on microplastic intake of fish species in shallow areas of a neotropical coastal lagoon
Researchers analyzed microplastic ingestion in six fish species from a coastal lagoon in Brazil and found that species sharing the same food sources tended to ingest similar amounts of microplastic fibers. Blue polyester fibers smaller than 0.05 mm were the most common type found, likely from textile pollution. Since fish dietary habits determine their microplastic intake, this affects which fish species accumulate more plastic particles and what ultimately ends up on people's plates.
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.
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.
Variability in the drivers of microplastic consumption by fish across four lake ecosystems
Researchers examined microplastic consumption by three fish species across four lakes in Minnesota and found that ingestion rates varied by species and feeding strategy. Filter-feeding fish consumed microplastics at rates that matched local water contamination levels, while visual feeders did not show the same pattern. The findings indicate that a fish's feeding behavior plays a major role in determining its microplastic exposure.
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.
Effect of biological and environmental factors on microplastic ingestion of commercial fish species
Researchers analyzed microplastic ingestion in commercially important fish species, evaluating how biological and environmental factors influence ingestion rates across 2,222 individual fish. The study assessed gastrointestinal tract contents to determine the extent and patterns of microplastic contamination. The findings suggest that both species-specific biology and environmental conditions play important roles in determining microplastic ingestion levels in commercial fish.
