Ecological Impacts of Common Carp Invasions: A Global Perspective

As an invasive species that is widely spread globally, common carp ( Cyprinus carpio ) has caused significant ecological impacts on aquatic ecosystems. The invasion of carp has not only disrupted the ecological balance in many areas, but has also had an economic impact on commercial and recreational fishing, increasing the cost of management and control. This study examines the global status of carp invasion and explores its ecological consequences on the destruction of native species, changes in food web dynamics, and impacts on water quality and sediments. This paper analyzes several cases to show the diversity impacts of carp invasions and the current management strategies, including physical removal, biological control and policy supervision, in order to provide an important theoretical basis for the integrated management of carp invasions and put forward the direction of future research.
