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.

Sterlet Acipenser Ruthenus

The Danube River was originally inhabited by six native sturgeon species, but currently, the sterlet (Acipenser ruthenus L.) is the only native sturgeon species still occupying the Slovak–Hungarian stretch of the Middle Danube. All sturgeon species are facing extinction, suffering from overfishing, water pollution, illegal fishing, poaching or other negative impacts. Urgent and proper actions are needed to prevent their extinction, and evaluating its genetic diversity is one of the essential tools of conservation programs. Since the management actions are primarily local in nature, we first focused on comparing and analysing local sources of fish for population recovery and natural (wild) population in the adjacent stretch of the Danube River. We used 2 fragments of mitochondrial DNA and 12 microsatellites to analyse the genotype of the three groups of sterlets, i.e. wild, broodstock and stocked individuals from Slovak part of the Danube. Mitochondrial markers of all groups were diversified similarly to populations from other parts of the Danube. This confirmed that broodstock and stocked fish belong to the original Danube population. Microsatellites revealed very similar patterns among groups compared, but we detected possible negative trends reflected in losing polymorphism in a few loci in broodstock and stocked individuals.
