SUMMARY:

The Penaeidae shrimp represent one of the most economically profitable fisheries resources in the world. Therefore, in several regions of the world there is a large investment in shrimp farms for the production of cultivated shrimp. Currently, the species P. vannamei, originally from the American Pacific Ocean, is among the most productive marine shrimp species in the world industry, however, the intense use of this species for farm has led to increasingly frequent records of its presence in ecosystems marine habitats, far from their native geographic distribution. Although these occurrences have already been registered in different places on the West Atlantic coast, all the reports point out that the lack of information and research does not allow to indicate the establishment of natural populations of this exotic species in the region, much less to determine its invasive potential. Based on this background, this thesis aims to investigate the possibility of establishment and the potential for invasiveness of this exotic species on the West Atlantic coast of America. In chapter 1 a ensemble model approach of niche in geographic space is used in conjunction with an ecological niche approach in environmental space to investigate the potential of establishment. Additionally, we evaluated the potential of P. vannamei niche overlap with other native species to determine its invasive potential. Chapter 2 proposes to assess the influence of climate change on the environmental suitability levels of P. vannamei on the west Atlantic coast, using the ensemble of habitat suitability models technique to represent the current status of the species distribution and compare with future, considering different scenarios predicted in global warming models. Chapter 3 aims to address the establishment of populations of the species from an in situ study, through the spatiotemporal investigation of the incidence of whiteleg shrimp in a natural area, close to large farm complexes of the species.
