ClearLow level of microplastic contamination in wild fish from an urban estuary
Researchers found low levels of microplastic contamination in 26 wild fish species from the Pearl River Estuary, South China, with abundance and polymer composition varying by species feeding strategy and habitat depth, suggesting that estuarine fish exposure depends substantially on ecological niche.
Microplastics Environmental Effect and Risk Assessment on the Aquaculture Systems from South China
Researchers surveyed microplastic contamination across aquaculture ponds in the Pearl River Estuary region of South China, examining water, sediment, and cultured organisms. They found microplastics present in all environmental media sampled, with higher abundances near areas of intensive human activity. The study provides a risk assessment indicating that microplastic pollution in aquaculture systems may affect both the farmed organisms and the safety of aquaculture products for human consumption.
The accumulation of microplastics in fish from an important fish farm and mariculture area, Haizhou Bay, China
Researchers investigated microplastic accumulation in six wild fish species from Haizhou Bay, a major fish farm and mariculture area in China, examining both digestive and non-digestive tissues. They found microplastics present in all fish species, with variation in abundance depending on species and tissue type. The findings raise concerns about microplastic transfer through aquaculture supply chains and potential implications for seafood safety.

Researchers assessed microplastic pollution across water, sediment, and marine organisms in Xiangshan Bay, a major mariculture area in China, finding that intensive aquaculture in the enclosed inner bay concentrated microplastics and that fish ingested more particles than other organisms.
Occurrence and distribution of microplastics in commercial fishes from estuarine areas of Guangdong, South China
Researchers analyzed the abundance, characteristics, and spatial distribution of microplastics in six commercial fish species from estuarine areas of Guangdong, South China, providing quantitative data on microplastic ingestion in fish from one of China's most plastic-polluted coastal regions.
Evidence for non-selective ingestion of microplastic in demersal fish
Researchers found that 54% of demersal fish stomachs in Hong Kong contained microplastics across five species, with no significant difference between species, wild versus farmed fish, or locations, suggesting non-selective ingestion, though fish near the Pearl River showed higher contamination frequency.
Microplastics in oysters Saccostrea cucullata along the Pearl River Estuary, China
Microplastics were found in oysters from multiple sites along the Pearl River Estuary in China, with concentrations varying by site and correlating with local microplastic levels in surrounding water. The results indicate that farmed and wild oysters in this heavily polluted estuary accumulate microplastics that could reach consumers.
Occurrence of microplastics in commercial fish from a natural estuarine environment
Researchers examined the gastrointestinal tracts of commercial fish caught from a natural estuarine environment and found microplastics in a significant proportion of individuals, documenting both occurrence rates and particle characteristics.
Characterization and spatial distribution of microplastics in two wild captured economic freshwater fish from north and west rivers of Guangdong province
Microplastics were found in two economically important freshwater fish species sampled across Guangdong Province, China, with fibers being the most common type and polypropylene and polyester the dominant polymers. The widespread contamination of commercial freshwater fish in China indicates a significant pathway for human exposure through fish consumption.
Microplastics in wild freshwater fish of different feeding habits from Beijiang and Pearl River Delta regions, south China
Microplastics were found in both surface water and the digestive tracts of wild freshwater fish from the Beijiang River and Pearl River Delta in southern China, with omnivorous fish containing roughly twice as many particles as carnivores. Fibers and fragments were the most common forms, and smaller particles under 1 mm predominated.
Microplastic pollution in the Maowei Sea, a typical mariculture bay of China
Researchers surveyed microplastic pollution in the Maowei Sea, a major mariculture bay in China, analyzing both water samples and fish from 12 species. They found microplastics in all fish gastrointestinal tracts and in the gills of many individuals, with demersal species showing significantly higher contamination than pelagic ones. The highest water concentrations were found near oyster nurseries and harbour areas, suggesting that farmed seafood from this region is regularly exposed to microplastic contamination.
Microplastics in different tissues of caught fish in the artificial reef area and adjacent waters of Haizhou Bay
Microplastics were ubiquitously detected in both gills and gut tissues of fish from the artificial reef area of Haizhou Bay and adjacent waters, with tissue-specific accumulation patterns and polymer types indicating that fish in artificial reef habitats are exposed to similar microplastic contamination as fish in natural habitats.
Microplastic contamination in highly consumed wild and cultured Asian seabass from a subtropical coastal region: Exposure and consumer risk assessment
Researchers compared microplastic contamination in wild and farmed Asian seabass from a subtropical coastal region and found plastic particles in the muscle tissue of both groups. Wild fish had slightly higher contamination levels than farmed fish, with polyethylene being the most common plastic type and most particles smaller than half a millimeter. The study includes a consumer risk assessment suggesting that regular consumption of this popular seafood species results in meaningful microplastic exposure for humans.
Microplastic prevalence in marine fish from onshore Beibu Gulf, South China Sea
Researchers examined 271 fish across 32 species from the Beibu Gulf and found microplastics in the majority of samples, with fibers being the most common type and abundance varying by species, feeding habits, and habitat.
Accumulation of microplastics in typical commercial aquatic species: A case study at a productive aquaculture site in China
Researchers assessed microplastic accumulation in commercial fish, bivalves, and shrimp at an intensive aquaculture site in Xiangshan Bay, China. They found microplastics in all species sampled, mostly cellulose and polypropylene fibers, with aquaculture activities contributing to sediment contamination. However, the overall accumulation levels in the seafood were relatively low, suggesting that microplastics may not substantially increase health risks from consuming these species at this site.
