Microplastics in the digestive tracts of commercial fish from the marine ranching in east China sea, China
AI summary Read the abstract
Researchers examined the digestive tracts of 125 commercial fish from 24 species in a Chinese marine ranching area, finding microplastics in 38% of individuals, predominantly blue and black fibers made of cellophane and cellulose. These findings provide baseline data on microplastic ingestion by seafood species in China's coastal marine environments.
Microplastics are emerging pollutants in aquatic and terrestrial environment. Monitoring the ingestion of microplastics by fish in the environment is crucial to understanding the risks posed by microplastics in the marine ecosystem. In this study, we investigated the ingestion of microplastics in commercial fish from the marine ranching in Ma’an Archipelago. Samples were taken in 13 sites where 125 fishes belonging to 24 species and three feeding habits were captured. Presence of microplastics was verified in the 37.6% of fishes. The fiber represented the 90.74% of microplastics found. Blue (30%) and black (27%) were the most prevalent colors. The average abundance of microplastics in the digestive tracts of sampled fish was 0.43 ± 0.69 items/individual. In addition, cellophane and cellulose were the most abundant types of microplastics identified. Our results provided useful information for evaluating the environmental risks posed by microplastics in China from the marine organisms’ angle.

Occurrence of Microplastics in the Gastrointestinal Tract and Gills of Fish from Guangdong, South China
AI summary Read the abstract
Researchers analyzed microplastic contamination in the gastrointestinal tracts and gills of eight commercial fish species from coastal Guangdong, China. They found an average of 6.6 microplastic particles per fish, with fibers under 1 mm being the most common type, and noted that herbivorous and omnivorous fish accumulated more microplastics in their digestive systems than carnivorous species.
Occurrence and accumulation of microplastics in commercial fish in the coastal waters of the Lvsi fishing ground in China
AI summary Read the abstract
Researchers examined microplastics in the gills and guts of 11 commercial fish species from a Chinese coastal fishing ground, finding that over 85% of fish contained microplastics in these tissues at levels of roughly 2–3 pieces per fish. PET fibers with a blue color were most common, and microplastic abundance did not increase with trophic level, suggesting limited biomagnification in this food web. Because many of these fish species are consumed by humans, understanding their microplastic loads is directly relevant to assessing human dietary exposure.
Microplastic uptake in commercial fishes from the Bohai Sea, China
AI summary Read the abstract
Researchers examined microplastic contamination in 584 commercial fish across 29 species from the Bohai Sea in China and found that approximately 85% had ingested microplastics. The particles were mostly fibers, primarily made of cellophane, PET, and polypropylene, with bottom-feeding fish showing the highest contamination. The findings suggest that microplastic ingestion by commercial fish species represents a potential pathway for human exposure, particularly through small fish consumed whole.
