The introduction of exotic species in aquaculture: A solution or part of the problem?

Abstract:

The introduction of alien species in new environments, as a consequence of human activities, contributes to an irreversible and devastating impact to natural ecosystems. As aquaculture is one source of this problem, this paper reviews the role of some governments and international organizations in the development of this activity. We conclude that these organizations should reconsider the use of technical packages that encourage introduction of exotic species. Instead, they should help the development of technologies that propose to cultivate native species with potential for aquaculture. This will require research to determine optimal conditions for culture, and it will improve local research capacities. International technical funding agencies can exert a great influence in encouraging new practices.
