Assessment on Microplastics Contamination in Freshwater Fish: a Case Study of the Ubolratana Reservoir, Thailand
Researchers examined microplastic contamination in freshwater fish from the Ubolratana Reservoir, Thailand, finding that 96.4% of 14 examined species had ingested microplastics, and assessed abundance, size, colour, and shape of particles from stomach and intestinal contents across sampling stations.
First Evidence of Microplastic Ingestion by Riverine Fish From the Freshwater of Northwest Peninsular Malaysia
Researchers found microplastics in the guts of multiple fish species from two rivers in northwest Malaysia, with some species averaging nearly 50 microplastic particles per gram of body weight. The dominant particles were fibers and fragments of polyethylene and polypropylene — findings that signal widespread contamination of freshwater food sources and raise concerns about human exposure through fish consumption.
Abundance and characteristics of microplastics in commercial marine fish from Malaysia
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.
Abundance, characteristics and variation of microplastics in different freshwater fish species from Bangladesh
Researchers examined 48 freshwater fish from 18 species in Bangladesh and found microplastics in the digestive tracts of over 73% of the fish studied. Fibers were the most common shape, and the plastics were primarily polyethylene and polypropylene-based polymers. Bottom-dwelling fish contained more microplastics than those living higher in the water column, suggesting that contaminated sediments are a significant source of exposure for freshwater species.

Researchers examined the digestive tracts of five commercially important fish species caught at a fish landing site in East Kalimantan, Indonesia, and found microplastics in all of them, with fibres and fragments being the most common types. This documents microplastic contamination in seafood from Indonesian waters and raises concerns about human dietary exposure through fish consumption.
Analysis of Microplastic Abundance in the Digestive Tract of Fish Caught by Fishermen in the Pangempang Waters of East Kalimantan Province
Researchers analyzed the abundance and types of microplastics in the digestive tracts of fish caught by fishermen in Pangempang Waters, East Kalimantan, and investigated the relationship between fish body size and microplastic content.
Occurrence, distribution and characteristics of microplastics in gastrointestinal tract and gills of commercial marine fish from Malaysia
Researchers examined 158 commercial marine fish from 16 species in Malaysia and found microplastics in the gastrointestinal tracts and gills of all species studied. Fibers were the most common microplastic type, and the contamination levels varied between sampling locations. The findings add to growing evidence that microplastics are widespread in commercially important fish species, raising questions about the potential for human exposure through seafood consumption.
Microplasticcontaminationincommercial marine fish: A case study in Johor, Malaysia
Researchers examined four species of commercially important marine fish from waters around Johor, Malaysia, and found microplastics present in the flesh of all species sampled. Fibers and fragments were the most common particle types, with polypropylene and polyethylene being the dominant polymers identified. The findings raise concerns about human dietary exposure to microplastics through commonly consumed fish in the region.
Occurrence and characterization of microplastic content in the digestive system of riverine fishes
Researchers found microplastics in 93.8% of riverine fish examined, with polystyrene, polyethylene, and nylon being the most common polymer types concentrated near urban and industrial areas, and small particles (0.025-1 mm) predominating across species.
Microplastic ingestion by commercial marine fish from the seawater of Northwest Peninsular Malaysia
Researchers examined microplastic ingestion by four species of commercially important marine fish caught off the northwest coast of Peninsular Malaysia. The study found microplastics in the gastrointestinal tracts of the fish, with fibers being the most common type, highlighting the prevalence of microplastic contamination in seafood from this region.
Pervasive Microplastic Ingestion by Commercial Fish Species from a Natural Lagoon Environment
Researchers examined microplastic contamination in the gastrointestinal tracts and gills of commercial fish species from a natural lagoon environment. Microplastics were found across all species examined, with fiber morphotypes dominant and contamination levels reflecting the lagoon's proximity to human activity and plastic pollution sources.
Microplastic contamination in freshwater fish: first insights from the Mekong River in Nakhon Phanom Province, Thailand
Researchers found microplastics in 100% of 89 fish gastrointestinal tracts sampled from the Mekong River in Thailand, averaging 23.76 items per individual, with fragments being the dominant shape (83%), particles under 100 µm the most common size, and 17 polymer types identified across species.
Occurrence of microplastics in fish gastrointestinal tracts belongs to different feeding habits from the Bangladesh coast of the Bay of Bengal
Researchers examined the gastrointestinal tracts of six commercial fish species from the Bangladesh coast of the Bay of Bengal and found microplastics in all species studied. A total of 696 microplastic particles were identified, ranging from 0.3 to 5 millimeters in size, with varying contamination levels across different feeding habits. The study highlights that microplastic pollution is widespread in commercially important fish from this region.
Occurrence of Microplastics in the Gastrointestinal Tracts of Edible Fishes from South Indian Rivers
Researchers isolated and characterized microplastics from the gastrointestinal tracts of five edible fish species collected from the Kollidam and Vellar rivers in Tamil Nadu, Southern India. They found 315 microplastic particles across 23 fish, dominated by fibers (85.7%) in Kollidam river fish and fragments (14.3%) in Vellar river fish, with particle sizes ranging from 109 to 284 µm, indicating widespread dietary exposure to microplastics in commercially harvested freshwater fish.
