Microplastic (MP) pollution has attracted wide attention since the production and use of plastic materials has increased worldwide. However, there is a lack of information about MPs in freshwater ecosystems, given that they are less studied compared to marine ones. Fish species are of special interest since they are utilized in the human diet. Among various sources, synthetic textiles play a dominant role in microplastic emissions, especially in the form of short fibers. The aim of this study was to determine the occurrence of MPs in the gastrointestinal tract (GIT) of the freshwater fish species common bream (Abramis brama Linnaeus, 1758) from the Danube River (1169 river km) in the area of the city of Belgrade, Serbia (44° 49′ 54.48″ N, 20° 27′ 23.68″ E). A total of nine specimens were collected, and the whole GIT was removed. Digestion of organic content was performed with a combined alkaline-oxidative treatment (10% KOH and Triton X-100; 30% H2O2). Filtered samples were visually observed under a binocular microscope. A total number of 136 plastic particles were detected, all belonging to a class of fibers. The size of the particles varied from 0.5 mm to 50 mm. The obtained results are in accordance with previous studies that reported fibers as the dominant shape of MPs in fish. The given results represent a contribution to the research of the MPs' occurrence in freshwater species. However, there is a need for further studies involving other fish species.
