The feeding habits and intestinal parasites of Pontic shad (Alosa immaculata Bennet, 1835) from the Danube river were investigated in 2016 and 2017. A total of 180 individuals were collected and examined. The ranges of total and mean length of examined migrants were: 20.3±30.6 to 30.5±36.3 cm for Prahovo locality, and 17.9±26.7 to 27.5±36.7 cm for the Danube Delta, respectively. Parasitic species were identified in 16 fish specimens (18.6%) from Prahovo and 94 fish specimens (100.0%) in the Danube Delta. Representatives of the phylum Nematoda, namely specimens from the Anisakidae family, Contracaecum sp., Contracaecum siniperca Dogiel & Achmerov, 1946 and Contracaecum bidentatum (Linstow, 1899) Skrjabin, 1917 were determined. Identified parasitic fauna shows low diversity, but the intensity and prevalence of infestation are relatively high. With regard to feeding habits, representatives of macrozoobenthos were identified in the intestinal contents, mostly the insect component (Diptera, Ephemeroptera, Plecoptera, Odonata and Planaria). Macrozoobenthos were more present in the intestinal content of Pontic shad captured in Prahovo than in the Danube delta. Also, the intestines of fish specimens from Prahovo contained other structures, such as algae, detritus, sand, and a few terrestrial insects.
Even though the Pontic shad represents a commercially important fish species in the lower section of the Danube, research on it in this area has been performed only sporadically.
