AB  - 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 sample, 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.

AB  - Veliki kormoran se u potpunosti hrani ribom. Dnevna količina hrane koju veliki
kormoran pojede kreće se između 425-700 grama, odnosno u proseku od 15 do 17 % svoje
telesne težine. Opsežnija istraživanja ishrane velikih kormorana u Srbiji nisu vršena. Jedini
podaci o ishrani kormorana i drugih ihtiofagnih vrsta ptica kod nas odnose se na štete koje
one nanose proizvodnji ribe na ribnjacima. Podaci o ishrani kormorana van ribnjaka odnose
se na ishranu tokom sezone gnežđenja u koloniji u Kopačkom ritu i zimsku ishranu na
akumulaciji Gruža. Analiza ishrane velikog kormorana i značaj šarana u njegovoj ishrani
rađena je na području Specijalnog rezervata prirode „Carska bara”. U periodu od 2007
do 2010 godine prikupljane su gvalice za analizu ishrane velikog kormorana. Gvalice su
prikupljane u dve sezone: sezona gnežđenja (mart-jun) i jesenje-zimskom periodu (oktobarfebruar).
Prikupljane su na mestima gde se ptice odmaraju i u samom mestu gnežđenja.
Analiza gvalica je najčešće korišćen metod analize ishrane kod kormorana. U periodu oktobar–
februar, 2007 – 2010. godine prikupljeno je 507 gvalica iz kojih su identifikovani
ostaci 2433 jedinke od 16 različitih vrsta riba, od kojih je 9 vrsta bilo iz familije Cyprinidae,
zatim tri vrste iz familije Percidae i po jedna vrsta iz familija Gadidae, Esocidae, Ictaluridae
i Gobiidae. Ostaci šarana identifikovani su u 184 gvalice (36,29%). Šaran je u ovom
periodu bio zastupljen sa 18,10%, u pogledu brojnosti. Po masenom udelu u plenu najznačajnija
je vrsta, sa učešćem od 36,24%. Tokom sezona gnežđenja od 2007. do 2010. godine prikupljeno je 80 gvalica. U plenu,
identifikovanom iz gvalica, po brojnosti su dominirale dve vrste, babuška i šaran, a
registrovano je prisustvo 11 vrsta riba iz 5 familija (6 Ciprinidae, 1 Ictaluridae, 1 Esocidae,
2 Percidae,1 Gobiidae). Ostaci šarana su registrovani u 44 (55%) gvalica. Šaranske vrste
riba su još značajnije zastupljene u ishrani kormorana tokom sezone gnežđenja nego u
jesenjem i zimskom periodu. Tako, one čine 85% ukupnog broja ulovljenih jedinki, a udeo
u biomasi plena je oko 90%. Rezultati istraživanja ishrane velikih kormorana na području
Carske bare u skladu su sa mnogim studijama sprovedenim širom Evrope.
