Production of exotic fish and Brazilian hybrids in similar conditions: Are there considerable differences of environmental performance?

In developing countries and tropical regions, earthen ponds have become an alternative for farming fish inland. Farmers usually restrict diet to compound feed, which is a relevant source of environmental impact. In the conditions described above, the motivation of this study was to evaluate the environmental impact of fish farming developed with different species. We evaluated systems producing the exotic Nile Tilapia (Oreochromis niloticus),...
