Non-native fish species are common in fish farming and fishing industries. However, when these species grow too many, they can harm the environment and threaten local species diversity. To tackle this issue, it is essential to manage and limit the growth of these non-native species. This management includes removing them from certain areas and stopping their spread to new places. Many developed countries are managing non-native species through methods such as direct eradication or the designation of banned species through laws, but they are not observing significant effects. In South Korea, an alternative strategy by the local governments is to purchase certain non-native species to control them. Therefore, our goal is to explore methods and research on controlling non-native fish species and suggest effective management approaches for these species.
