The sterlet is the last regularly documented native sturgeon species in the Slovak-Hungarian stretch of the middle Danube. The current status of the species is generally unknown because there is lack of the data. There is no commercial fishing there and the only reliable data are the catches recorded by Slovak Anglers Club Union. We have used the data on the catches and the weights of all sampled sterlets between the yeas 2003 and 2014. Catches are continuously decreasing and the average height is increasing. Two hypotheses are available, the changes in angling practises to catch larger fishes or the increasing age of the population. The angling practises changed in last two decades with using larger hooks with favourite baits so there is higher probability to sample larger specimens. On the other hand, the number of sampled individuals are decreasing as well. Further research is needed to uncover the population characteristics of the sterlet in the middle Danube as well as to increase of the knowledge of spawning, feeding and wintering habitats.
