Microplastic pollution of commercial fishes from coastal and offshore waters in southwestern Japan

Marine Pollution Bulletin 2022 50 citations

Microplastics were found in the digestive tracts of seven fish species from coastal and offshore waters near Kyushu, Japan, with contamination rates and particle characteristics differing between pelagic and demersal species and between coastal and deeper water habitats.

Body Systems

Microplastic (MP) pollution in the marine environment is a worldwide issue. There is growing concern of consuming MPs through fish, yet the contamination status of fish collected from deeper waters surrounding Japan remains limited. Here, we presented baseline data on MPs in commercially important fishes from the coastal and offshore waters near Kyushu, Japan (East China Sea). We examined the MPs in the digestive tracts of two pelagic (n = 150) and five demersal species (n = 235). The fish were caught by pole and line, and bottom trawl at different geographical positions. The MPs in pelagic fish (39.1%) were more than in demersal fish (10.3%) and were of larger sizes. Moreover, the MPs correlated with habitat depth and type and species variation in the shape and polymer composition of MPs was observed. The results increase our understanding of the heterogeneous uptake of MPs by fishes.

Occurrence of Microplastics in Digestive Tracts of Fish with Different Modes of Ingestion in Japanese Bays and Lake Biwa

AI summary Read the abstract

Researchers examined microplastics in the digestive tracts of seven fish species from five Japanese bays and Lake Biwa, finding particles in 37% of the 197 fish sampled. Filter-feeding fish had significantly higher microplastic ingestion rates than non-filter-feeders, suggesting that feeding mode is a key factor in microplastic exposure.

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.

Abundance and characteristics of microplastics in commercial marine fish from Malaysia

AI summary Read the abstract

Microplastics were found in the digestive tracts of eight commercially important marine fish species caught in Malaysian waters, with prevalence and particle types varying by species and location. The study raises food safety concerns for Malaysian seafood consumers and highlights the widespread occurrence of microplastic ingestion in wild-caught fish from Southeast Asian seas.
