Megjegyzések:	In the last decades numerous riverbed settlement and regulation activities were implemented on the River Öreg-Túr to improve the riverine conditions and water retention features of the river. As a result, the flow conditions of the river have changed significantly influencing the composition of organism community of the water including the fish fauna. The aim of this work was to examine the effect of these anthropogenic interventions on the fish fauna. A total of 1301 individuals of 22 species were identified monitoring the fish fauna in the whole length of the River Öreg-Túr (from Sonkád to Tisza mouth) and in the three main tributaries in autumn 2015 and in spring 2016. The majority of the individuals were found in the upper region of the river. Conservation and ecological assessment based on fish communities indicated a deterioration in conservation value from the source toward the mouth of the river. Three sections with good and three sections with bad ecological value were identified on the main river while all three tributaries could be classified as poor or bad in this qualification system. Our results show that certain barrages have an obvious negative impact on the fish fauna by damming the water, though dredging carried out in an ecologically appropriate way may have positive impact on the fish communities.
