Microplastic in Gastrointestinal Tracts of European Sea Bass
Summary
This study examined microplastics found in the gastrointestinal tracts of European sea bass caught in the Mediterranean. The detection of microplastics in commercially important food fish raises concerns about human dietary exposure through seafood consumption.
Abstract In this study, it was aimed toinvestigate the presence of microplastics in the gastrointestinal tract of the culturedsea bass (Dicentrarchus labrax). The gastrointestinal tracts of sea bassfish with an average weight of 264 g obtained from net cages in the sea in theAegean region in June were separated and kept in KOH solution for the digestionof organic substances and the separation of microplastics for the purpose ofmicroplastics examination. Suspected microplastic samples were examined andphotographed under a stereo microscope. Suspected microplastics in the gastrointestinaltracts of sea bass are classified as fiber, film, fragment and granules inshape. Suspected microplastics in the form of film (23,8 pieces/fish) was morecommonly, followed by fiber (21,3 pieces/fish) and fragment (14 pieces/fish),with particles in the form of least granules (2,71 pieces/fish). When suspectedmicroplastics were sorted by their colors, a total of %19,5 transparent, 32,4%brown, 2, 6% yellow colors were found in the form of films and a small amountof other colors were found. The colors of the fiber shapes are 17,2%transparent, 14,5% black and 10,9% blue microplastics, followed by 4,7% yellowcolored fibers. In fragment shapes, 21,1% transparent colors, 5,5% yellowcolors were commonly obtained and other colors were found in small amounts. Theleast common granular-shaped suspected microplastics were found to be 2v blueand 2% brown granules. Keywords: Microplastics,Aquaculture, European sea bass, Gastrointestinal tract.

Evidence of microplastic ingestion by cultured European sea bass (Dicentrarchus labrax)
Researchers evaluated, for the first time, microplastic presence in farmed European sea bass cultivated in coastal waters of Tenerife, Canary Islands. They found that 65% of the 83 examined fish contained microplastics in their gastrointestinal tracts, demonstrating that cultured fish are also exposed to microplastic contamination, not just wild-caught species.
Microplastic occurrence in the gastrointestinal tract and gill of bioindicator fish species in the northeastern Mediterranean
Four commercial fish species from the northeastern Mediterranean were examined for microplastic presence in gastrointestinal tracts and gills, with plastics found in all species and fiber being the most common type. The results add to growing evidence that microplastic ingestion is routine for commercially harvested Mediterranean fish.
Microplastics Presence in Cultured and Wild Sea Bream Gasrointestinal Tract
This study detected and characterized microplastics in the gastrointestinal tracts of both wild-caught and farmed sea bream from the Adriatic Sea. Finding microplastics in both farmed and wild fish indicates widespread environmental contamination and raises food safety questions for seafood consumers.
Occurrence of microplastics in the gastrointestinal tracts of some edible fish species along the Turkish coast
Researchers examined the gastrointestinal tracts of 243 individual fish from five edible species along the Turkish coast, documenting the occurrence and characteristics of ingested microplastics. The study found microplastics present in multiple commercially important fish species, raising implications for seafood safety and human dietary exposure.
Microplastics occurrence in the Tyrrhenian waters and in the gastrointestinal tract of two congener species of seabreams
Microplastics were found in both seawater and the gastrointestinal tracts of two commercially important Mediterranean fish species, Pagellus erythrinus and P. bogaraveo, collected from the Tyrrhenian Sea. The study highlights the prevalence of microplastic contamination in edible fish and raises concerns about human dietary exposure through seafood consumption.
