ClearMicroplastic contamination in the aquaculture icon Oreochromis mossambicus: Prevalence, characteristics, and comprehensive overview
Researchers investigated microplastic contamination in the Mozambique tilapia, a widely farmed fish species in India, and found microplastics present in the digestive tracts of sampled fish. The most common types were fibers and fragments made of polyethylene and polypropylene. The study raises concerns about microplastic transfer through aquaculture to human consumers, given the growing importance of tilapia farming and the rising levels of plastic pollution in Indian freshwater systems.
Correlation of Water Quality with Microplastic Exposure Prevalence in Tilapia (Oreochromis niloticus)
Researchers exposed tilapia to polyethylene microplastics at three concentrations and assessed effects on water quality and microplastic accumulation in gastrointestinal, liver, gill, and gonad tissues, finding that higher concentrations were associated with elevated microplastic prevalence and tissue-specific accumulation patterns.
Do microplastics pose health hazard?: A laboratory study by Oreochromis niloticus
Researchers used Nile tilapia (Oreochromis niloticus) in a tank-based experiment to quantify microplastic accumulation and assess health risk using a total polymer risk index. The study found elevated health risk levels in fish exposed to environmental concentrations of MPs, suggesting risks extending to human consumers.
Challenges to Aquatic Food Source Sustainability: Investigating the Bioaccumulation of Microplastics of Tilapia and Mussels
This study investigated microplastic bioaccumulation in aquatic food sources including fish, shellfish, and crustaceans, examining contamination levels across commercially important species and assessing the human dietary exposure implications of consuming aquatic foods from contaminated environments.
Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
Researchers analyzed microplastic pollution in commercially important seafood species, characterizing particle morphology and polymer composition across species. The study found microplastics in all species sampled, with differences in contamination levels linked to feeding ecology and habitat.
Occurrence and Impacts of Microplastics in Freshwater Fish
This review summarizes research on microplastic occurrence in freshwater fish across multiple regions, examining ingestion rates, polymer types, and potential health effects. The authors highlight that freshwater fish are widely exposed to microplastics and call for more standardized monitoring to assess risks to fish and to people who eat them.
Evaluation of Toxicological Risks and Effects of Microplastics on Nile Tilapia (Oreochromisniloticus) under in Vitro Laboratory Conditions
This laboratory study evaluated the toxicological effects of microplastics on Nile tilapia (Oreochromis niloticus) under controlled conditions, finding measurable harm at the concentrations tested. The results have implications for managing fish health in aquaculture operations with microplastic-contaminated water.
Integrated Biomarker, Histopathological and Genotoxicity‐Based Toxicological Evaluation of Polystyrene and Polyethylene Microplastics in Oreochromis mossambicus
Researchers exposed Mozambique tilapia to polystyrene and polyethylene microplastics and found dose-dependent accumulation in gill, gut, and liver tissues. Polyethylene proved significantly more toxic, causing greater oxidative stress, metabolic disruption, and chromosomal damage as measured by micronucleus assays. The study provides evidence that different polymer types can have markedly different toxicological impacts on freshwater fish.
Microplastics Contamination in the Edible Fish Mozambique Tilapia (Oreochromis mossambicus) from the Selvampathy Wetland of Coimbatore, Tamil Nadu, India
Microplastics were found in the guts, gills, and muscle tissue of tilapia caught from a wetland in Tamil Nadu, India, with fibres making up 95% of particles and polyethylene the dominant polymer. Because tilapia is a widely eaten fish, these findings raise direct food-safety concerns about microplastic transfer to human consumers, and the study points to urban discharge and agricultural runoff as the likely pollution sources.
Occurrence of Microplastics in the Tissues of Nile Tilapia (Orechromis niloticus) from Zobe Dam, Katsina State, Nigeria
This study found microplastics in the tissues of Nile tilapia cultured in freshwater, with particles identified in gills, intestines, and muscle tissue. The results highlight the potential for microplastic transfer from farmed fish to human consumers.
Microplastic Analysis in Catfish Mystus gulio (Hamilton 1822) and Tilapia Oreochromis niloticus (Linnaeus 1758) from Tirunelveli District, Tamil Nadu, India
Researchers examined microplastic contamination in the gastrointestinal tracts of two commercially important fish species, catfish (Mystus gulio) and tilapia (Oreochromis niloticus), collected from the Thamirabarani River in Tamil Nadu, India, characterizing MP morphology, color, and size using microscopy.
Worldwide contamination of fish with microplastics: A brief global overview
A literature review from March 2019 to March 2020 synthesized worldwide data on microplastic contamination in fish, finding that a median of 60% of fish from 198 species across 24 countries contained microplastics in their organs. Carnivorous species ingested more microplastics than herbivores, consistent with trophic transfer and bioaccumulation through food webs.
Microplastics in Fish: A Comprehensive Review
This review synthesizes research on microplastics in fish, covering contamination sources, detection methods, and impacts on wild and farmed populations globally — and examining how plastic particles in fish tissues may transfer to humans through seafood consumption.
Abundance, characteristics, and risk assessment of microplastics in indigenous freshwater fishes of India
Researchers examined microplastic contamination in five widely consumed freshwater fish species from India and found plastic particles in all specimens, with fibers being the most dominant type. Evidence of microplastics in edible fish tissue indicates translocation from the gut, suggesting a pathway for human exposure through consumption. Risk assessment showed that while microplastic abundance posed a low quantitative risk, the polymer types identified indicated a high hazard potential for the fish species studied.
Histological and Histochemical Effects of Microplastics Administration in Oreochromis niloticus Fingerlings
Researchers exposed Nile tilapia to two types of microplastics and examined histological and histochemical changes in gills, liver, and kidneys, finding tissue-level damage that demonstrates the harmful effects of microplastic ingestion on vital fish organs.
Bioavailability and toxicity of microplastics to fish species: A review
This review summarizes current knowledge about microplastic ingestion and its toxic effects in fish species worldwide. Researchers found that microplastics have been detected in fish from nearly all types of aquatic habitats, and both field and laboratory studies confirm fish are highly susceptible to ingesting these particles. The study notes that microplastics alone or combined with other pollutants can cause various health problems in fish, raising concerns about implications for human seafood consumption.
