Identification of microplastic shapes, colors, and sizes
Average of 11.33 ± 3.71 MPs in the gastrointestinal tract and 7.67 ± 2.96 MPs in gills per fish
Dominant microplastic shape was fragment (59.8%) and color was black (58.8%)
Dominant sizes were 200-500 µm in intestinal tissue and 50-200 µm in gill tissues.

Abstract

In the present study, microplastic (MP) ingestion by Barbus cyri fish species found in the Acıçay Stream was investigated. In this context, Microplastics (171 MPs: 59.6 % gastrointestinal tract, and 40.4 % gills) were detected in this fish species’ different tissues. The average abundance of MP was found to be 11.33 ± 3.71 MP items/individual in the gastrointestinal tract tissue and 7.67 ± 2.96 MP items/individual in the gills. The most dominant shape of detected microplastics in fish tissues is fragment (59.8%) and most dominant color is black (58.8 %). Additionally, the dominant sizes of MPs in fish samples were determined as 200-500 µm in intestinal tissue and 50-200 µm in gill tissues. The dominant polymer was ethylene propylene (48.6 %). The results of this study provide supply fundamental data for the management of MPs in fish species in freshwater systems and for taking the necessary precautions.
