Cronologia da invasão e status de distribuição do gastrópode invasor Melanoides tuberculata (Müller, 1774) (mollusca, thiaridae) no Brasil

Abstract

Brazil is internationally recognized for its flora and fauna, but like other countries, it has been losing its biological biodiversity due to the presence of exotic species in the national territory, caused by the pursuit of economic growth. Even so, there are few studies and research focused on exotic species in the national territory, even with the increase in their occurrences in recent years in the country and the great biodiversity that Brazil has. The introduction of most exotic species that are present in Brazil today occurred accidentally, as is the case of the exotic species studied in this work, Melanoides tuberculata, which entered the country along with ornamental fish, through fish farming and navigation. Its first record in Brazil was in the municipality of Santos, state of São Paulo, and today it is found in almost all states of the country, due to its high population density, low mortality, high birth rates, the difficulty of its elimination or reduction and the high financial value demand for the operation. Thus, the present study aims to carry out a scientific literature review about the bioinvasion of Melanoides tuberculata in Brazilian continental waters. Analyze its distribution in the states of Brazil and the Amazon region, analyze the chronology and possible routes of introduction in the Amazon states, its origin, morphological characteristics and its reproductive process. The study also presents information on the negative impacts on the environment, health and economy caused by the presence of these species in the country. The bibliographic survey also presents some actions that have already been taken by researchers and other actions that can be carried out by scholars, researchers, authorities and competent bodies to prevent the expansion, reproduction, dominance and population stabilization of invasive species in aquatic ecosystems in Braz.
