THE FAUNA OF ENDOPARASITES IN ACIPENSER RUTHENUS LINNAEUS, 1758 FROM THE SERBIAN PART OF THE DANUBE RIVER

Abstract

Abstract — Helminths of sterlet (Acipenser ruthenus L.) from the Danube River were studied as a part of ichthyoparasitological research in Serbia. The fish were collected during the period of 2002 – 2003 along the Danube's course through the Belgrade region. A total of 517 specimens of sterlet of different ages (0+ to 1+) were examined. Helminths were found in 342 or 66.15 % of the collected specimens. The examined fish yielded a total of 13 helminth species: four species of Trematoda, one species of Cestoda, four species of Nematoda, and four species of Acanthocephala
