Microplastic and artificial cellulose microfibers ingestion by reef fishes in the Guarapari Islands, southwestern Atlantic
AI summary Read the abstract
Reef fish from the southwestern Atlantic were found to have ingested microplastics and artificial cellulose microfibers, with six species showing particularly high ingestion rates and fiber types dominating over hard plastic fragments.
This study investigated the ingestion of microplastics and artificial cellulose particles by 103 specimens belonging to 21 reef fish species from the southwestern Atlantic. Specimens of six species had ingested microplastics and artificial cellulose particles, while those of another three species had ingested only one type of material. In our samples, man-made cellulose fibers were more common than microplastics. The tomtate grunt, Haemulon aurolineatum, ingested more particles than any of the other species. Overall, transparent particles were predominant, and polyamide was the most common plastic material. Household sewage, fishery activity, and navigation appear to be the principal sources of the artificial particles ingested by the reef fishes. Our results provide an important database on oceanic contamination by microplastics and artificial cellulose particles. Understanding this impact on tropical reef fish will contribute to the development of strategies to mitigate pollution by anthropogenic debris in reef systems.

Widespread microplastic ingestion in Colombian Caribbean marine fish: Trophic influence, spatial-temporal trends, and polymer composition
AI summary Read the abstract
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
AI summary Read the abstract
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.
Microplastic ingestion by pelagic and benthic fish and diet composition: A case study in the NW Iberian shelf
AI summary Read the abstract
Researchers found microplastics in 78% of fish examined across four pelagic and benthic species from the NW Iberian shelf, with ingestion rates varying by feeding ecology and habitat depth, and identified predominantly fibers and fragments in gastrointestinal contents following alkaline tissue digestion.
Anthropogenic particles ingestion in fish species from two areas of the western Mediterranean Sea.
AI summary Read the abstract
Anthropogenic particles including microplastics were found in the digestive tracts of fish from two aquatic environments, with ingestion rates and particle types varying by species and location. The study documents widespread microplastic ingestion across fish species in different habitat types.
