ClearCan the Fulton and hepatosomatic indexes be good indicators of charity of the baltic fish according to microplastics pollution?
Researchers assessed microplastic contamination and health condition indices in herring and five bycatch species from the Baltic Sea, finding MPs in all species with the highest occurrence in lumpfish (78.9%). The Fulton condition factor and hepatosomatic index showed limited correlation with MP burden, suggesting these standard health metrics may not reliably indicate MP-related physiological stress.
Microplastic Intake, Its Biotic Drivers, and Hydrophobic Organic Contaminant Levels in the Baltic Herring

The study contributed to baseline knowledge of microplastic ingestion rates in commercially important fish species in European seas.
The first report on the occurrence of microplastics in commercial fish species and surrounding water from the Baltic Sea (Poland)
Researchers conducted the first comprehensive study of microplastic occurrence in commercial fish species and surrounding water from the Polish Baltic Sea, characterizing particle abundance and properties while examining the poorly understood relationship between microplastic concentrations in organisms and their surrounding habitat.
Plastic in digestive tracts and gills of cod and herring from the Baltic Sea
Researchers found plastic particles in the digestive tracts and gills of Baltic Sea cod and herring, with ingestion rates and particle types differing between the two species, indicating widespread exposure of commercially important fish to plastic pollution.
Comparative study on microplastic abundance in fish organs from marine and freshwater ecosystems of the southern Baltic Sea region: influence of habitat zone and feeding preferences
Researchers found microplastics in 58% of 500 fish specimens examined across Baltic Sea and northern Polish freshwater ecosystems, with carnivorous and benthic species showing the highest contamination levels and blue fibers being the most common particle type across all habitats.
Microlitter in Fish and Benthic Invertebrates of the NE Baltic Sea: Abundance, Composition and Bioindicators
Researchers characterized microlitter abundance, composition, and bioindicator potential in fish and benthic invertebrates from multiple sites in the NE Baltic Sea, including the Gulf of Finland, Gulf of Riga, and western Estonia, following HELCOM methodology. Examining 11 fish species and 6 benthic invertebrate species collected during 2019-2020, the study evaluated resident marine fauna as monitors of microplastic contamination.
Microplastic ingestion by fish: Body size, condition factor and gut fullness are not related to the amount of plastics consumed
Researchers examined microplastic ingestion in commercial cod and saithe collected in Iceland, finding particles in about 20% of cod and 17% of saithe stomachs. No significant relationship was found between microplastic ingestion and fish body size, weight, gut fullness, or condition index.
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.
Comprehensive systematic review and meta-analysis of microplastic prevalence and abundance in freshwater fish species: the effect of fish species habitat, feeding behavior, and Fulton’s condition factor
A meta-analysis of freshwater fish across 42 studies found an average of 2.35 microplastic items per individual, with 80% of research focused on the gastrointestinal tract and 58% on river environments. Contrary to expectations, microplastic ingestion correlated with fish body physiology (size and weight) rather than feeding behavior or habitat, suggesting physical characteristics determine uptake more than ecological niche.
Testing the health status of marine and fresh waters by investigating microplastics in the stomach contents of different fish species
This PhD project investigated microplastic presence in stomach contents of fish from four sites ranging from a commercial port to a lake, characterizing microplastic types and abundances to assess environmental health status across marine, brackish, and freshwater ecosystems.
Plastic ingestion by pelagic and demersal fish from the North Sea and Baltic Sea
Researchers examined gastrointestinal tracts of 290 North and Baltic Sea fish and detected plastic in 5.5% of individuals, with pelagic species like herring and mackerel ingesting plastic at three times the rate of bottom-dwelling cod and flounder, and polyethylene making up nearly 40% of identified polymer types.
Microplastics in Commercial Fishes and By-Catch from Selected FAO Major Fishing Areas of the Southern Baltic Sea
Researchers found microplastics in both edible and non-edible organs of five fish species from the southern Baltic Sea, with 1-12 particles per fish dominated by fibers, and polymers including cellophane, polyamide, polyethylene, and polypropylene identified by FTIR spectroscopy.
High microplastics concentration in liver is negatively associated with condition factor in the Benguela hake Merluccius polli
Researchers quantified microplastics in gills, liver, and muscle of 94 Benguela hake caught commercially off northwest Africa, finding that high liver microplastic concentrations were negatively correlated with fish body condition, suggesting physiological costs of microplastic accumulation.
Fish species, habitat, and capture location outweigh fish mass as drivers of microplastic pollution in Canadian Arctic fishes
Researchers investigated microplastic contamination in 435 stomachs and gastrointestinal tracts of seven freshwater fish species from the Canadian Arctic. The study found that fish species, habitat type, and capture location were more important drivers of microplastic levels than fish size, with demersal species and those near larger human populations containing significantly more microplastics.
Microplastics abundance in four different species of commercial fishes in Bali Strait
Four commercially important fish species in the Bali Strait, Indonesia all contained microplastics in their gastrointestinal tracts, with fragments and fibers being most common. As these fish are widely consumed, this raises concerns about microplastic transfer to humans through the seafood supply chain.
Effective and easy to use extraction method shows low numbers of microplastics in offshore planktivorous fish from the northern Baltic Sea
Microplastics were found at low levels in planktivorous fish from the northern Baltic Sea using a validated alkaline digestion extraction method. The study demonstrates an efficient, validated protocol for detecting microplastics in fish and provides baseline contamination data for Baltic marine food webs.
Occurrence, distribution and characteristics of microplastics in gastrointestinal tract and gills of commercial marine fish from Malaysia
Researchers examined 158 commercial marine fish from 16 species in Malaysia and found microplastics in the gastrointestinal tracts and gills of all species studied. Fibers were the most common microplastic type, and the contamination levels varied between sampling locations. The findings add to growing evidence that microplastics are widespread in commercially important fish species, raising questions about the potential for human exposure through seafood consumption.
Microplastic contamination and biological alterations in Atlantic wild fish populations, and human health risks associated to fillet consumption
Researchers found microplastics in the gastrointestinal tracts, gills, liver, brain, and muscle tissue of wild Atlantic pouting and hake fish, and the contamination was linked to measurable biological changes in the fish. The study also estimated human health risks from eating these fish fillets, developing a new index that combines microplastic intake levels with the hazard level of the specific plastic types found. This work provides a direct link between microplastic pollution in wild fish and potential risks to people who eat seafood regularly.
