Investigations of hemato-biochemical and histopathological parameters, and growth performance of walking catfish (Clarias batrachus) exposed to PET and LDPE microplastics
Researchers exposed walking catfish to PET and LDPE microplastics for 60 days and observed significant changes in blood parameters, including decreased red blood cells and increased white blood cells. Tissue damage was found in the liver and gills, and fish growth was reduced compared to unexposed groups. The study suggests that bottom-dwelling fish species may be particularly vulnerable to microplastic contamination in their habitat.
Toxicity of co-exposure of microplastics and lead in African catfish (Clarias gariepinus)
Researchers exposed African catfish to lead, microplastics, and a combination of both for 15 days and found that the combined exposure was more harmful than either pollutant alone. The mixture caused the greatest damage to blood cells, triggered stronger inflammatory responses, and disrupted the fish's antioxidant defenses. Since microplastics can carry heavy metals like lead on their surfaces, this study shows how microplastics may amplify the toxic effects of other pollutants in freshwater fish that people eat.
Virgin microplastics cause toxicity and modulate the impacts of phenanthrene on biomarker responses in African catfish ( Clarias gariepinus )
Researchers investigated the impacts of virgin and phenanthrene-loaded polyethylene microplastic fragments on juvenile African catfish. The study found that even virgin microplastics caused toxicity and altered biomarker responses, and that microplastics modulated the toxic effects of phenanthrene, suggesting microplastics can act as both independent stressors and carriers of chemical contaminants.
Human health and ecological risks associated with microplastic contamination in widely consumed catfish from a large-scale estuary
Researchers quantified microplastic contamination in two commercially important catfish species from the Meghna Estuary in Bangladesh, analyzing gills, digestive tracts, and muscle tissue.

Ecotoxicological effects of low-density polyethylene microplastic on Heteropneustes fossilis: behavioral, hematological, biochemical, and histopathological impacts
Scientists exposed freshwater fish to tiny plastic particles (microplastics) from everyday items like plastic bags and found they caused serious health problems including blood disorders, organ damage, and weakened immune systems. The higher the amount of plastic particles, the worse the damage became to vital organs like gills, intestines, and liver. This matters because these same microplastics are found throughout our food chain and water supply, raising concerns about potential health risks for humans who consume contaminated fish and water.
Comparative toxicity of virgin and biodegraded LLDPE microplastics on growth, behavior, antioxidant, and hematological health of Catla catla fish
Researchers compared the toxicity of virgin versus bacterially degraded polyethylene microplastics on freshwater fish, finding that both types caused abnormal behaviors and disrupted blood parameters in a dose-dependent manner. However, biodegraded microplastics produced less severe effects on growth, survival, and antioxidant enzyme activity, suggesting that microbial degradation may reduce the ecological risk posed by microplastic pollution.

The Effect of Polystyrene Microplastic Exposure in the Rearing Water on Muscle Morphology of Mutiara Catfish (Clarias gariepinus Burchell, 1822)
Catfish (Clarias gariepinus) were exposed to polystyrene microplastics at 0, 1, 10, and 100 mg/L for 28 days and muscle tissue was examined histologically. Microplastics accumulated in muscle tissue in a dose-dependent manner, and myofiber diameter and area decreased significantly at higher concentrations, indicating microplastic-induced muscle damage.
Increased transfer of trace metals and Vibrio sp. from biodegradable microplastics to catfish Clarias gariepinus
Researchers compared the transfer of trace metals and Vibrio bacteria from conventional and biodegradable microplastics to catfish. They found that biodegradable microplastics actually transferred more metals and pathogens to the fish than conventional plastics. The study suggests that biodegradable alternatives may not be safer for aquatic organisms and could potentially increase contaminant exposure through ingestion.
Polystyrene microplastics exposure in freshwater fish, Labeo rohita: evaluation of physiology and histopathology
Researchers fed freshwater fish varying levels of polystyrene microplastics for 90 days and found dose-dependent damage to blood health, growth, and organ tissues. Higher microplastic concentrations caused more severe harm to the liver, kidneys, gills, and intestines. The study highlights that microplastics in freshwater systems can accumulate in fish and cause significant health problems, raising concerns about food safety for communities that rely on freshwater fish.
Toxic effects of microplastic (polyethylene) exposure: Bioaccumulation, hematological parameters and antioxidant responses in crucian carp, Carassius carassius
Researchers exposed crucian carp to polyethylene microplastics at various concentrations and found that the particles accumulated in tissues including gills, gut, and liver. The microplastics altered blood cell counts and disrupted the fish's antioxidant defense system in a dose-dependent manner. The study suggests that even common polyethylene microplastics can cause measurable biological harm in freshwater fish.

The study showed that microplastic exposure increased respiratory rates and significantly reduced swimming speed, travel distance, and movement in the fish compared to controls.
RETRACTED ARTICLE: An assessment of physiological and health responses in Catla catla fingerlings after polystyrene microplastic exposure
Note: This article has been retracted. The study reported that feeding polystyrene microplastics to Catla catla fish reduced growth, impaired blood health, decreased nutritional quality, and caused intestinal damage. Higher concentrations of microplastics led to worse outcomes across all measures. While the retraction means these specific results should be viewed with caution, the general concern about microplastic effects on farmed fish remains supported by other research.
Accumulation, tissue distribution, health hazard of microplastics in a commercially important cat fish, Silonia silondia from a tropical large-scale estuary
Researchers found microplastics in the digestive tract, gills, and edible muscle tissue of a commercially important catfish species from a major tropical estuary. The most common types were PET, polyethylene, and polypropylene fibers likely originating from fishing nets and sewage. Since these microplastics were found in the muscle tissue that people eat, the study raises direct concerns about human microplastic exposure through seafood consumption.
