ABSTRACT :
The trophic spectrum study examines the relationship between fish and macroinvertebrates, which are their prey. The study involved investigating the stomach contents of Barbus meridionalis petenyi and interpreting the data using
synthetic and analytical ecological indices. Macroinvertebrates were identified using a stereomicroscope and determination keys to reach the smallest taxon possible. The synecological analysis revealed that almost all the macroinvertebrates found in
the fish’s stomach contents belonged to the Insecta Class. The Diptera Order had the highest abundance values, while the Coleoptera Order had the lowest ones. The study demonstrated that Mediterranean barbel has a generalist feeding mode and a broad food spectrum, which are their most relevant characteristics.
