During the years 2019-2020, research was carried out on the assessment of the health status of fish in the upper Danube sector of Romania. Fish species belonging to the families Ciprinidae, Siluridae, Esocidae, Percidae, Clupeidae and Acipenseridae were analyzed. Fish were sampled from two stations: Station 1- km 1048, near Moldova Nouă and Station 2- km 493, near Giurgiu. The parasitological analyzes were performed in the laboratory of the Institute of Research and Development for Aquatic Ecology, Fishing, and Aquaculture (ICDEAPA), Galati, Romania. Analyzes were performed on fresh fish using well-known methods. In station 1, 14 species of parasites belonging to eight systematic groups were identified: Nematode, Monogenea, Trematode, Ciliata, Acanthocephala, Protozoa, Cestoda, Crustacea, while in station 2, 11 species of parasites belonging to six systematic groups were identified: Monogenea, Ciliata, Trematoda, Nematoda, Acanthocephala, Cestoda. The species Sander lucioperca and Abramis brama presented most often polyparasitoses but with a low degree of infestation. The most present group of parasites in station 1 was represented by nematodes and in station 2 by monogenic worms.
