Microplastics Ingestion by Skipjack tuna (Katsuwonus pelamis) in Ternate, North Maluku - Indonesia
Summary
Researchers found microplastics in the digestive tracts of skipjack tuna collected from Indonesian waters, with plastic particles present in most fish examined. Since tuna is widely consumed, the findings raise concerns about human exposure to microplastics through seafood.
Abstract Microplastic (MPs) is a contaminant of concern worldwide. Rivers are implicated as significant pathways of micro-plastic transport to marine and lake ecosystems, and microplastic ingestion by freshwater biota is a risk associated with microplastic contamination, but there is little research on microplastic ecology within freshwater ecosystems. Microplastic uptake by fish is likely affected by environmental microplastic abundance and aspects of fish ecology, but these relationships have rarely been addressed. We measure the distribution and abundance of micro-plastic in skipjack tuna from 3 markets in Ternate. In total 948 MPs pieces were obtained in 16 fish samples. The identified MPs characteristics show that the micro-plastic character is categorized from the type of fiber, film, and fragment, while the colour of microplastic is black, red, blue, green, brown, grey, and white.

Analysis the Abundance and Composition of Microplastics in Skipjack Fish (Katsuwonus pelamis) at Muara Angke Fish Auction
Researchers analyzed the abundance and composition of microplastics in the digestive tracts of skipjack tuna (Katsuwonus pelamis) collected from Muara Angke Fish Auction in Indonesia, using 10% KOH digestion to extract microplastics and assess contamination levels in a commercially important marine species.
Microplastic contamination in the Skipjack Tuna (Euthynnus affinis) collected from Southern Coast of Java, Indonesia
Researchers examined the digestive tracts of skipjack tuna collected from the southern coast of Java, Indonesia, and found microplastics present in all sampled fish. The most common microplastics were fibers and fragments, primarily made of polyethylene and polypropylene. The findings raise concerns about microplastic contamination in commercially important fish species consumed by humans in the region.
Toxic tuna tales: Tracing microplastic pathways in mackerel tuna (Euthynnus affinis), longtail tuna (Thunnus tonggol), and bullet tuna (Auxis rochei)
Researchers examined 125 tuna from three species in Malaysian waters and found microplastics in their digestive tracts, gills, and edible muscle tissue. Fibers were the most common type, and male fish accumulated more microplastics than females. Since tuna is one of the most widely consumed fish globally, the presence of microplastics in edible muscle tissue raises direct concerns about human exposure through seafood.
A Systematic Review of Microplastic Contamination in Tuna Species: General Pathways into the Food Chain with Ecotoxicological and Human Health Perspectives
This systematic review found that tuna species worldwide contain significant levels of microplastics, especially polyethylene and polypropylene, concentrated in their gills and digestive tracts. Since tuna is one of the most widely consumed fish globally, these findings mean that eating tuna is a direct route for microplastic exposure in the human diet.
Environmental and ecological risk of microplastics in the surface waters and gastrointestinal tract of skipjack tuna (Katsuwonus pelamis) around the Lakshadweep Islands, India
This study assessed microplastic contamination in surface waters and the gastrointestinal tracts of skipjack tuna around the Lakshadweep Islands, India. Researchers found widespread microplastic presence in both environmental and biological samples, indicating that even remote oceanic island ecosystems are affected by plastic pollution.
