Comparative study of microplastic ingestion in commercial fish species from macaronesia
AI summary Read the abstract
Researchers analyzed the gastrointestinal contents of 634 fish from seven commercial species across all four Macaronesian archipelagos to compare microplastic ingestion rates by species, habitat, and feeding behavior. They found microplastics across all species and locations, with ingestion rates varying by species ecology, contributing baseline contamination data for commercially important fish in this Atlantic island region.
The Gastrointestinal (GI) content of 634 fish belonging to seven species from the four Macaronesian archipelagos were analysed to study the ingestion of microplastics (MP). Fish species were selected based on their habitats, feeding behaviour, and commercial value in each archipelago accounting for a total of 181Katsuwonus pelamis, 121 Scomber colias, 121 Pagrus pagrus, 60 Mullus surmuletus, 60 Aphanopus spp., 70 Cephalopholis taneopsis and 21 Selar crumenophthalmus. Prior to dissection, all specimens were weighed and measured for total length. The GI tract was weighed and digested with a 10 Also see: https://micro2024.sciencesconf.org/558611/document

Considering ecological traits of fishes to understand microplastic ingestion across Pacific coastal fisheries
AI summary Read the abstract
Researchers assessed microplastic contamination in coastal fish across four Pacific Island nations (Fiji, Tonga, Tuvalu, and Vanuatu) using standardized methods. By analyzing 878 fish across multiple species, they found that ecological traits such as feeding behavior and habitat use influenced microplastic ingestion patterns, providing important context for understanding contamination risks in Pacific coastal fisheries.
Effect of biological and environmental factors on microplastic ingestion of commercial fish species
AI summary Read the abstract
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.
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 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.
