Invasive carp can outcompete native species for resources, leading to declines in native fish populations and overall biodiversity (Britton, 2022). For example, in mesocosm experiments, the presence of common carp reduced the growth of native fish species, although this effect was mitigated by higher native species richness. Furthermore, common carp invasions can lead to the extirpation of sensitive species, such as the endangered river snail in Australian rivers, due to predation and habitat alteration (Marshall et al., 2019). The introduction of common carp can also cause genetic introgression and the transmission of non-native pathogens, further threatening native biodiversity. These impacts underscore the importance of managing common carp populations to preserve native biodiversity and ecosystem function. 7.3 Climate change and invasive potential Climate change is expected to exacerbate the invasive potential of common carp. As global temperatures rise, the range of suitable habitats for common carp is likely to expand, increasing the risk of invasion in new areas (Závorka et al., 2018). Climate change can also alter hydrological cycles and nutrient dynamics, creating conditions that favor the establishment and spread of invasive species like common carp. For instance, increased water temperatures and nutrient availability can enhance the growth and reproductive success of common carp, further facilitating their invasion. Additionally, the combined effects of climate change and biological invasions can lead to more severe ecological impacts, such as altered food web dynamics and reduced ecosystem resilience (Shackleton et al., 2018). Therefore, understanding the interactive effects of climate change and invasive species is crucial for predicting and managing future invasions. 8 Concluding Remarks The invasion of common carp (Cyprinus carpio) has been shown to significantly impact aquatic ecosystems globally. Key findings from the reviewed literature indicate that common carp invasions lead to increased water
