Microplastic Content in the Gastrointestinal Tract of Some Fish Species of Lake Kubenskoe (Vologda Oblast)
AI summary Read the abstract
Researchers quantified microplastic content in the gastrointestinal tracts of perch, roach, and bream from Lake Kubenskoe in the Vologda region of Russia, representing the first evidence of microplastic contamination in fish from Vologda Oblast water bodies. MPs were detected in 60% of bream and 43% of perch individuals but not in roach, with average loads of 1.6 particles per bream and 4.2 particles per perch, predominantly in fiber form.
Quantitative assessment of microplastic content in the gastrointestinal tract of perch, roach and bream of Kubenskое Lake in the Vologda region was conducted. Microplastics were detected in 60% of bream specimens and 43% of perch specimens. No plastic microparticles were found in the gastrointestinal tract of the roach. It was found average number of microplastic particles was 1.6 ± 0.4 items per individual of bream, and 4.2 ± 1.4 items of microplastic per individual of perch. Microplastics in the gastrointestinal tract of fish were mainly represented by fibers with a small proportion of fragments and films. No significant differences (р 0.05) in the content of microplastics in the gastrointestinal tract of benthivorous (bream) and euryphage (perch) were found. The data obtained are the first evidence of the presence of microplastics in fish of the Vologda Oblast water bodies.

Microplastic Content in the Gastrointestinal Tract of Some Fish Species of Lake Kubenskoe (Vologda Oblast)
AI summary Read the abstract
Researchers analyzed gastrointestinal contents of fish species from Lake Baikal for microplastic particles, finding plastics in a proportion of sampled fish across multiple species. Fibres dominated the ingested particle types, and microplastic occurrence correlated with proximity to tourist and recreational areas along the lakeshore, linking human activity to plastic ingestion in this globally important freshwater system.
Microplastic in Abiotic and Biotic Parts of the Mesha Bay of the Kuibyshev Reservoir (Republic of Tatarstan)
AI summary Read the abstract
Researchers measured microplastic content in water, bottom sediments, and the gills and gastrointestinal tracts of bream (Abramis brama) at the mouth of the Mesha River in the Kuibyshev Reservoir, Russia, finding concentrations of 20.5 units/m3 in water, 44.7 units/kg in sediments, and 12.3 and 14 units per fish in gills and gut respectively. The study documented microplastic accumulation across abiotic and biotic compartments of a large inland reservoir, confirming trophic transfer of plastic particles into commercially relevant fish.

Microplastic particles (0.15-5.0 mm) were found in 62% of 141 freshwater fish examined from the Ob and Yenisei rivers in Siberia, with prevalence ranging from 18.5% in Yenisei perch to 92.6% in Ob ruffe. Fibers accounted for up to 99.7% of all detected particles across the three fish species studied.

Microplastic pollution in perch (Perca fluviatilis, Linnaeus 1758) from Italian south-alpine lakes
AI summary Read the abstract
Researchers examined microplastic ingestion in European perch (Perca fluviatilis) from four Italian alpine lakes, finding MPs in the gastrointestinal tracts of all sampled fish with fibers as the dominant type and higher ingestion rates in fish from more urbanized lake catchments.
