The gills and mouth of the fish allow microplastics to enter the body. Microplastic contamination of the fish body can have a variety of consequences, including increasing toxicity and growth suppression. This research was conducted to study microplastics in fish collected from Tobruk Bay basin. A total of 61 fish samples were caught and collected. An icebox was used to keep and transport the samples to the laboratory. The form and size of microplastics were discovered and examined in each gill and gastrointestinal tract of the collected fish samples. Samples' gills and gastrointestinal tracts are separated from their bodies. Microplastics were observed under the light microscope. The results showed that the investigation of the gills and digestive gut revealed that all studied fishes (100.0%) were contaminated by microplastics. The chi-square test revealed the insignificant association between the size of microplastics found in fish gill and digestive tract with fish species. Also, the results showed an insignificant association between the size of microplastics in fish gill and gut with fish size. This study recommends further research on microplastic contamination in marine organisms and fish
