The stomach content of 277 Amur sleeper individuals has been analyzed to present its
feeding habits. Fish were sampled using electrofishing from July to November 2017 in
the Danube River drainage channel near Veliko Gradište (Serbia). Fish age was
estimated by otoliths examination. Ingested prey organisms were identified to the
lowest reliable taxonomic level. The biotic indices: vacuity index (VI), frequency of
occurrence (F), abundance (Cn), index of importance (PV), Shannon’s diversity index
(H’), and equitability index (Eh) were calculated. A total of 18 prey categories and 1144
individual prey were identified in the fish diet, dominantly aquatic macroinvertebrates.
There were no significant difference in diet composition between sampling months as
well as 0+, 1+, and 2+ age groups (both 3+ and 4+ had one individual). Only eight
individuals were found with empty intestines, thus VI was low (2.9). In average, each
fish had 4.1 prey items in their intestines. For whole sam...ple, H′ was 1.84 and Eh was
0.64. Trichoptera, Ephemeroptera, and Gastropoda were the most frequent,dominant, and abundant. The greatest diversity of prey items was recorded for fish sampled in October as well as for 2+ individuals, and the lowest for fish from August and 0+ individuals.
