ClearDeleterious Effects of Polypropylene Microplastic Ingestion in Nile Tilapia (Oreochromis niloticus)
Researchers fed Nile tilapia daily doses of polypropylene microplastics for 30 days and observed significant health effects including changes in blood cell counts, altered gut bacteria, and tissue damage to the intestines and liver. The higher dose group showed more pronounced effects, including elevated inflammatory markers and signs of oxidative stress. The study provides evidence that chronic ingestion of microplastics commonly found in aquatic environments can cause meaningful harm to a widely consumed fish species.
Microplastics in aquaculture - Potential impacts on inflammatory processes in Nile tilapia
Researchers fed Nile tilapia a diet containing a mixture of four common microplastics and found that the particles triggered inflammatory responses in both adult and juvenile fish. The microplastics activated immune pathways and caused tissue changes in the gut and other organs, with juveniles being more sensitive. Since tilapia is one of the most widely farmed fish in the world, these findings raise concerns about the safety of farm-raised fish exposed to microplastic-contaminated water.
Effects of Microplastics on the Oxygen Consumption and Histological Changes of the Cultured Nile Tilapia Oreochromis niloticus
This study found that microplastic exposure caused tissue damage in the gills and intestines of tilapia fish, with higher concentrations leading to more severe changes. Since tilapia is widely consumed worldwide, these findings raise questions about whether microplastics in farmed fish could affect the quality and safety of the seafood on our plates.
Toxicological assessment of dietary exposure of polyethylene microplastics on growth, nutrient digestibility, carcass and gut histology of Nile Tilapia (Oreochromis niloticus) fingerlings

Fish exposed to the highest microplastic concentration (10%) showed severe gut damage visible under a microscope. Since tilapia is widely farmed for human consumption, these findings raise concerns about microplastic contamination affecting both fish health and the safety of farmed seafood.
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.
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.
‘The Plastic Nile’: First Evidence of Microplastic Contamination in Fish from the Nile River (Cairo, Egypt)
Researchers provided the first evidence of microplastic contamination in fish from the Nile River in Cairo, Egypt, finding that over 75% of sampled Nile tilapia and catfish contained microplastics in their digestive tracts, with fibers and fragments being the dominant particle types.
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.
Antioxidants and molecular damage in Nile Tilapia (Oreochromis niloticus) after exposure to microplastics
Researchers exposed juvenile Nile Tilapia to different concentrations of microplastics for 15 days followed by a recovery period. The study found dose-dependent increases in oxidative stress markers, DNA fragmentation, and altered protein patterns in fish exposed to microplastics. Evidence indicates that while fish exposed to the lowest concentration recovered after the treatment ended, higher doses caused more persistent damage.
Assessment the effect of exposure to microplastics in Nile Tilapia (Oreochromis niloticus) early juvenile: I. blood biomarkers
Researchers exposed juvenile Nile tilapia to different concentrations of microplastics for 15 days followed by a 15-day recovery period and measured blood biomarkers. They found dose-dependent changes in biochemical and hematological parameters, including elevated liver enzymes, altered blood cell counts, and increased glucose levels. Many of these effects persisted even after the recovery period, suggesting that microplastic exposure can cause lasting physiological stress in young freshwater fish.
Plastic pollution in fish (O. niloticus and C. gariepinus) in a Nile Canal, Delta of Egypt.
Researchers examined microplastic contamination in the gastrointestinal tracts of 127 Nile tilapia and 32 African catfish from a Nilotic canal in Egypt's Delta, finding microplastic occurrence rates of 33.9% and 59.4% respectively with fibers as the dominant morphology. The study analyzed the relationship between microplastic ingestion and fish biological parameters, feeding habits, and seasonal variation.
Assessment of microplastic-contaminated liver through gene expression profiling of four commercial fish species in the Lagos Lagoon, Nigeria
Researchers analyzed the livers of four commercial fish species from the Lagos Lagoon in Nigeria and found microplastic contamination in all of them. Gene expression analysis revealed that the microplastic accumulation triggered changes in genes related to stress response and immune function. The study raises concerns about potential health risks for people who regularly consume fish from polluted urban waterways.
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.
Comprehensive understanding the impacts of dietary exposure to polyethylene microplastics on genetically improved farmed tilapia (Oreochromis niloticus): tracking from growth, microbiota, metabolism to gene expressions
Researchers investigated the impacts of dietary polyethylene microplastics on genetically improved farmed tilapia over nine weeks, tracking effects on growth, gut microbiota, liver metabolism, and gene expression. The study found that microplastic exposure altered gut microbial communities, disrupted liver metabolic processes, and affected gene expression in brain and liver tissues. The findings suggest that microplastic contamination in fish feed and aquatic environments poses risks to farmed fish health.
Assessment of dietary polyvinylchloride, polypropylene and polyethylene terephthalate exposure in Nile tilapia, Oreochromis niloticus: Bioaccumulation, and effects on behaviour, growth, hematology and histology
Nile tilapia fish fed three common types of microplastics (PVC, polypropylene, and PET) showed reduced growth, abnormal behavior, blood cell damage, and tissue damage in their gills, liver, and intestines. The harmful effects increased with higher doses of microplastics and varied by plastic type. Since tilapia is one of the most widely consumed fish globally, these findings raise concerns about the health of fish that may carry microplastic contamination to human diets.
Biochemical, Genotoxic and Histological Implications of Polypropylene Microplastics on Freshwater Fish Oreochromis mossambicus: An Aquatic Eco-Toxicological Assessment
Researchers fed polypropylene microplastics to freshwater tilapia and found they caused oxidative stress, DNA damage, and liver tissue deterioration, with more severe effects after 14 days compared to acute 96-hour exposure. The microplastics disrupted antioxidant enzyme systems and neurotransmitter activity in the fish. The study demonstrates that prolonged microplastic ingestion poses a significant ecological threat to freshwater fish species.
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.
How do fish consume microplastics? An experimental study on accumulation pattern using Nile tilapia (Oreochromis niloticus)
Researchers fed Nile tilapia in controlled lab conditions to study how microplastics accumulate in fish organs. They found that most microplastics came from the fish feed rather than from particles floating in the water, and that the digestive tract accumulated the most particles while muscles, the part humans typically eat, contained the smallest sizes. Twelve different polymer types were identified across the fish tissues.
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.
