Biological invasions are among the main causes of biodiversity loss on planet. Losses are accentuated in streams, which are sensitive to human impacts, since they have specialized fauna and higher degree of endemism. Despite this, studies on invasions by non-native fish in streams are incipient in Brazil. In this review, we present an introduction on the process (i.e., stages) of biological invasion, the environmental factors that influence the establishment and the impacts of non-native species in streams. A methodological step-by-step is also presented as a way to guide the conduct of studies on non-native species in Brazilian streams. In addition, management actions measures are presented to prevent new cases of introductions and suggestions for studies on invasions in streams. Avoiding propagule pressure and environmental education, as well as legal aspects of Brazilian legislation, are management actions that can prevent new introductions. Finally, gaps in knowledge and perspectives are raised as an incentive for interested parties to enter the subject and develop new studies on non-native fishes in Brazilian streams.
