| Abstract | ||||
| Plastic pollution is an international problem to the limit that World Environment Day, made its theme on the 5th of June 2023: Beat plastic pollution. The Nile is suspected to be a source of such pollution that pour into the Mediterranean Sea. In this respect, the present work was carried out on 127 O. niloticus, as a surface feeder, and 32 C. gariepinus from Bahr Shebeen Nilotic Canal. The occurrence of microplastics varied with species and seasons. This did not exceed 10 particles per fish. The percentage occurrence was 33.9 for O. niloticus and 59.4 for C. gariepinus. Food and feeding and seasonal variations were examined and discussed, in the light of the shape and color of MPs with the length of fish. Colors of pink, red, and blue showed the highest occurrence in either species, while Fragments and fibers were found to be the highest. Identified polymers were shown to be polyamide, alkyd resins, polyethylene, polyethylene terephthalates and rayon. The highly occurring of those are polyamides and rayon in both species. | ||||
