Título.https://repositorio.ifal.edu.br/handle/123456789/3093In 2021, the Maceió sururu extractive community reported the constant appearance of a mollusk similar to the native sururu, but with a whitish color, which soon came to be called “white sururu” (Mytilopsis sallei) by riverside dwellers. Later, in 2022, the disappearance of the native sururu, Mytella falcata, was reported. Considering that the sururu is an Intangible Cultural Heritage of Alagoas, being a source not only of income, but also of food for a significant portion of the population, it is essential to carry out studies aimed at elucidating the incursion of this invasive bivalve into the Estuarine Complex Mundaú-Manguaba Lagoon (CELMM). Thus, this study aimed to understand the process of invasion of the “white sururu” in the lagunar Complex, as well as understanding the relationship between the establishment of the invasive species in the region and the disappearance of the species of sururu native to it, from the perspective of fishermen. Sururu from the Estuarine Complex.This study had a qualitative focus, using exploratory and descriptive field research as its methodological contribution. On-site visits were carried out in the region, as well as at Fishermen's Associations, presenting the theme and objectives of this research. 31 informants were interviewed, 90.30% of whom were male, with an average age of 56 years and an average fishing age of 36 years. Fishermen still associate the emergence of the white sururu with the “disappearance” of the native sururu, which is evidenced by many studies of the harmful effects on the environment and the native species that inhabit it as a result of the introduction of invasive species. However, according to the evidence, the “disappearance” of the native sururu may be more linked to changes in salinity and climate than the presence of the invasive bivalve. The disappearance of the native sururu, in turn, caused profound and severe effects on the riverside community, especially for those who survived from fishing, forcing the “sururuzeiros” to migrate to other regions and/or jobs. Knowledge about the invasive species is still incipient for the fishermen interviewed, especially when compared to knowledge about the native species. Fishermen consider the white sururu to be stronger and more resistant to the conditions established in the environment, representing a real danger to the native sururu, which represents the main source of subsistence for them and their families. Thus, the riverside community shows great concerns about the adverse effects of the incursion of the white sururu into laguna Mundaú. Therefore, the difficulties faced by local communities, exacerbated by the scarcity of native sururu, highlight the urgent need for conservation strategies that integrate traditional knowledge with the sustainable management of natural resources.ptBivalveCELMNMytella falcataEtnobiologiaSururuEthnobiologyDissertaçãoCIENCIAS BIOLOGICAS
