Microplastic exposure disrupted reproductive biology in both males and females, raising concerns about how environmental microplastic contamination affects fish reproduction.
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.
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. The study found tissue-specific patterns of microplastic accumulation and assessed both ecological and human health risks, highlighting concerns about dietary exposure through fish consumption in regions where fish is a primary protein source.
Effects Of Microplastics On Fish Physiology
This review examines how microplastic exposure affects fish physiology, covering accumulation patterns in different tissues, effects on organ function including liver and gill damage, antioxidant responses, and potential reproductive health consequences from both solo and combined contaminant exposures.
Toxic effects of microplastic and nanoplastic on the reproduction of teleost fish in aquatic environments
This review summarizes research on how microplastics and nanoplastics harm the reproductive systems of fish, covering effects on fertility, sperm quality, egg development, and offspring abnormalities. The tiny plastic particles enter fish through their digestive tract, gills, and skin, causing oxidative damage that disrupts reproduction at the molecular and cellular level. Since fish are a major protein source for humans, reproductive damage to fish populations could affect both food security and the transfer of microplastics through the food chain.
The Effect of Polyvinyl Chloride (PVC) Microplastic Exposure in Feed on The Growth Performance and Survival of Catin Fish (Pangasius hypophthalmus)
This study tested how PVC microplastics in feed affect the growth and survival of catfish. It found that microplastic exposure reduced fish growth performance, demonstrating how plastic contamination in aquatic environments can impact the food chain and potentially the seafood people eat.
The gonadal health status of Cyprinidae fish species collected from the river impacted by anthropogenic activities
Not relevant to microplastics — this study assesses reproductive health in three freshwater fish species from a Turkish river contaminated by heavy metals from agricultural and industrial wastewater, with no mention of microplastics.
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.
Environmental microplastics accumulate in gonads in a sex-dependent manner and alter reproductive success in zebrafish (Danio rerio)
Zebrafish exposed to environmentally sourced microplastics accumulated particles preferentially in the testes rather than ovaries, and males showed the highest gonadal microplastic loads along with PCB co-contaminant effects including inhibited apoptosis and hepatotoxicity.
Histological and Histochemical Effects of Microplastics Administration in Oreochromis niloticus Fingerlings
