Groenvlei in the Western Cape is one of only a handful of natural freshwater lakes in South Africa. The lake is home to two native and five non-native fish species. Introduced over an extended period some of these non-native fish have arguably added value to the water. However local anglers, subsistence fishers, and environmental managers have become increasingly concerned that illegally introduced common carp Cyprinus carpio have altered water quality and led to a decline in target sport and food fish. Carp control measures using both conventional netting as well as bow-fishing have been employed. This study draws together a wealth of data sources to explore the ecology and impact of carp in this environment and examine the efficacy and acceptability of management options tested.
