The study found microplastics present in both species, highlighting the riverine pollution burden and potential for human dietary exposure through fish consumption.
Microplastics in silver catfish (Chrysichthys nigrodigitatus) from new Calabar River in Niger Delta, Nigeria
Microplastics were found in about 56% of silver catfish from New Calabar River in Nigeria's Niger Delta, with an average of 3.87 particles per fish, mostly fragments, highlighting freshwater microplastic contamination risks in West African river systems.
Abundance and Seasonal Variation Of Microplastics Detected in Edible Fish Sold in Lagos State, Nigeria
This Nigerian study examined microplastic contamination in three commercially sold fish species (catfish, red snapper, and tilapia) across different seasons in Lagos State, finding microplastics in every single fish sampled. Fiber-shaped particles were most common, with higher abundances detected during the rainy season, and polyethylene was the dominant polymer type identified. The findings raise food safety concerns for consumers of seafood in West Africa, where monitoring data on microplastic contamination in fish are scarce.
Assessment of fishes, sediment and water from some inland rivers across the six geopolitical zones in Nigeria for microplastics
Researchers analyzed fish, sediment, and water samples from inland rivers in Nigeria for microplastic contamination, finding particles across all matrices sampled. The study provides baseline pollution data for a region with limited prior microplastic monitoring.
Analysis of microplastic contamination and associated human health risks in Clarias gariepinus and Oreochromis niloticus from Kubanni Reservoir, Zaria Nigeria
Researchers assessed microplastic contamination in two commercial fish species from Kubanni Reservoir in Nigeria and found fibers to be the most abundant particle type, with concentrations varying by season. The fish showed signs of oxidative stress and cellular damage in gills, liver, and muscle tissue that correlated with microplastic ingestion levels. The study raises concerns about potential human health risks from consuming contaminated fish, particularly for children who may exceed safe exposure thresholds.
Xenobiotic Microplastic Pollutants in the Silver Catfish (chrysichthys Nigrodigitatus, Lacépéde, 1803) Harvested from the Ikpoba River, Benin City, Nigeria
Researchers examined microplastic contamination in the silver catfish (Chrysichthys nigrodigitatus) harvested from the Ikpoba River in Nigeria, quantifying MP levels and characteristics in this commercially important species to assess food web contamination and potential human dietary exposure.
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.
Eco Toxicological Assessment of Micro Plastic Ingestion in Freshwater Fishes: A Case Study on Bioaccumulation and Histopathological Alterations
Researchers assessed microplastic accumulation in three freshwater fish species (tilapia, rohu, catla) from a major river system, finding microplastics in gastrointestinal tracts and associated histopathological damage in gills, liver, and kidneys.
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.
Microplastics Pollution of Water, Sediment, and Selected Fish Species from Bayelsa State, Nigeria
Researchers sampled water, sediment, and multiple fish species from three communities in Sagbama, Bayelsa State, Nigeria, to characterize microplastic contamination across aquatic compartments. Microplastics were detected in all matrices, with fibers dominating, establishing baseline contamination data for this Niger Delta region where residents rely heavily on local fish for food.

Characterization of Microplastics Residue in Water and Biota of Majidun Estuarines, Lagos Nigeria
Researchers characterized microplastics in surface water and commercially harvested aquatic species from the Majidun River estuary in Lagos, Nigeria, providing the first documented assessment of microplastic pollution in this location. Multiple polymer types were identified in both water and biota samples.
Characterisation of Ingested Microplastic Particles and Textile Microfibres in the Gastrointestinal Tract of Demersal Fish from a Peri-Urban Open Access Lagoon in Lagos Nigeria
Researchers characterized microplastic particles and textile microfibres in the gastrointestinal tracts of demersal fish from multiple genera caught in a peri-urban lagoon bordering Lagos, Nigeria. They found evidence of microplastic ingestion across multiple fish species, contributing to the limited but growing body of data on microplastic exposure in West African aquatic food webs.
Survival Rate and Growth Length of Catfish (Clarias gariepinus) Exposed to Microplastics
This study found that catfish exposed to microplastics showed reduced survival rates and slower growth compared to unexposed fish. The results are concerning because catfish is a widely farmed and consumed freshwater species, and microplastic contamination in aquaculture environments could affect both fish welfare and the quality of seafood reaching consumers.
Microplastics in carnivorous fish species, water and sediments of a coastal urban lagoon in Nigeria
Researchers investigated microplastic presence in water, sediment, and carnivorous fish species from the Lagos Lagoon in Nigeria for the first time. The study found microplastics across all environmental compartments and in three fish species, suggesting that microplastic contamination is widespread in this coastal urban lagoon ecosystem and may enter local food chains.
