| Abstract: | Hydropeaking and invasive non-native fish species are among the most significant pressures to riverine ecosystems and freshwater biodiversity, yet, fish responses to hydropeaking and the effectiveness of mitigation measures remain largely uncharted. This study addressed this gap through an indoor flume experiment assessing how two flow events influenced the use of artificial habitats (flow refuges) by the invasive non-native common carp (Cyprinus carpio). Fish behaviour was evaluated for a base flow (continuous 7 L/s) and a peak flow (increase from 7 L/s to continuous 60 L/s). Refuge use was quantified within three regions of two flow refuges alongside physiological responses (glucose and lactate) to stress and fatigue. Results were compared with previous findings for the native Iberian barbel (Luciobarbus bocagei) tested under the same conditions. No significant differences in lactate or glucose levels were observed between flow events for either species. In contrast, both species showed significantly higher frequency and duration of refuge use during peak flow. The native Iberian barbel displayed more frequent and prolonged refuge use than common carp, suggesting a stronger dependence on these structures for hydrodynamic sheltering. These findings raise concerns that intensified competition for flow refuge use may impede native species' access to these structures. [ABSTRACT FROM AUTHOR] |
