Chloroacetanilide herbicides are widely used in the agricultural sector throughout world. Because of their poor biodegradability, high water solubility, and long persistence, chloroacetanilide have a potential to contaminate water, conventional treatment processes do not ensure sufficient removal. Therefore, heterogeneous photocatalysis using TiO2/UV-A was investigated for degradation alachlor,...

In this study, fish species diversity and protection criteria, habitat evaluation, threat elements of the ichthyofauna Devrez Stream were examined monthly between April 2020 March 2021. Eight taxa (7 natives, 1 non-native) belonging to four families (Cyprinidae, Gobionidae, Leuciscidae, Gobiidae) identified.

Abstract The recent expansion of the round goby ( Neogobius melanostomus ) in tributaries lower Danube (Bulgaria) prompted assessing potential negative effects on local fish fauna such as competition for food resources. Diet overlap between and native fishes was analyzed using samples macroinvertebrates collected monthly a one-year period. Significant dietary N. Barbus petenyi , Perca fluviatil...

This study examines the impact of boldness on foraging competition highly invasive round goby Neogobius melanostomus Pallas 1815. Individual risk tolerance, or boldness, was measured as time to resume movement after a simulated predation strike. Fish that resumed faster were categorized bold, fish took more shy and those fell in between these two categories determined have intermediate boldness...
