Correlation of Water Quality with Microplastic Exposure Prevalence in Tilapia (Oreochromis niloticus)
Summary
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.
The highly use of polyethylene plastics in Indonesia has negative impact toward freshwater aquaculture systems. Omnivorous fish is one of the freshwater biota that exposed by microplastics. This study aims to determine the effect of microplastics to water quality and the prevalence of microplastic exposure in tilapia. The experimental design is conducted using a microplastic exposure (polyethylene scrub) with concentration of 0.01 g/L (P1), 0.1 g/L (P2), and 1 g/L (P3). Each treatment is repeated 3 times. The organ groups observed are the gastrointestinal, liver, gills, and gonads. The stages of the research including fish raising, microplastic extraction, water quality measuring parameter, and counting the amount of microplastics. The result obtained for water quality parameter is temperature, pH, and dissolved oxygen still within safe fish farming limit. Microplastics at high concentration in water can cause a decrease in the total value of ammonia and do not affect the value of water temperature, pH, and dissolved oxygen. Microplastics are found in the digestive organs, liver, gills, and gonads. The digestive tract of tilapia is the organ with the most microplastics after 14 days of exposure. It is concluded that microplastic is harmful for the life of tilapia because it can absorb to the liver and gonads.

Microplastic 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.
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.
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.
Deleterious 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.
