Toxicological assessment of dietary exposure of polyethylene microplastics on growth, nutrient digestibility, carcass and gut histology of Nile Tilapia (Oreochromis niloticus) fingerlings
Researchers fed Nile tilapia fish diets containing different amounts of polyethylene microplastics and found that higher levels significantly reduced growth, nutrient absorption, and body composition. 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.
Growth performance, hematological and oxidative stress responses in Nile tilapia (Oreochromis niloticus) exposed to polypropylene microplastics
Nile tilapia fish fed polypropylene microplastics for 7 weeks showed significantly reduced growth, blood abnormalities indicating anemia, and oxidative stress damage in both liver and brain tissue. The effects were dose-dependent, with higher microplastic concentrations causing more severe harm. Since tilapia is one of the most widely farmed and consumed fish globally, these findings raise concerns about the health of both farmed fish and the people who eat them.

Yeast supplementation showed protective effects against microplastic-related stress in the fish.
Spirulina platensis supplementation remediates microplastics-induced growth inhibition and stress in Nile tilapia, Oreochromis niloticus
Nile tilapia fish exposed to microplastics showed reduced growth, intestinal damage, and signs of immune stress, but adding the dietary supplement Spirulina to their feed significantly reversed these harmful effects. Spirulina reduced oxidative stress and helped repair gut damage caused by microplastic exposure. While this is a fish study, it suggests that certain natural supplements might help protect against some of the biological damage caused by microplastic ingestion.
Assessing the recovery of steroid levels and gonadal histopathology of tilapia exposed to polystyrene particle pollution by supplementary feed
Researchers investigated whether supplementary feed containing probiotics and vitamin C could mitigate the reproductive harm caused by polystyrene particle exposure in tilapia, assessing steroid levels and gonadal histopathology after exposure. Results indicated that plastic particle pollution negatively affected tilapia reproduction and that probiotic and vitamin C supplementation offers a potential dietary strategy to counter these effects.
Effects of Microplastics on Gene Expression, Muscular Performance, and Immunological Responses in Nile Tilapia (Oreochromis niloticus): Seasonal and Habitat Variations
Researchers found microplastics in both the gut and muscle tissue of Nile tilapia fish from two sites along the Nile River in Egypt, with contamination levels varying by season and location. The microplastics activated genes linked to muscle wasting, cell death, and inflammation while suppressing growth-related genes, with the worst effects seen during summer months. Since tilapia is a widely consumed fish, these findings raise concerns about microplastic-related damage being passed to humans through the food supply.

Chlorella alleviates the intestinal damage of tilapia caused by microplastics
Researchers investigated how polyethylene microplastics of different sizes affect the intestinal health of tilapia and whether Chlorella algae supplementation could alleviate the damage. They found that microplastics caused intestinal histological changes and disrupted enzyme activities, gene expression, and gut microbiota in the fish. The addition of Chlorella showed potential to mitigate some of the intestinal damage caused by nanoscale microplastic exposure.
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.
