The erosion of rural watersheds, especially in the rainy season, deposit sediments in the waterways, and subsequently brings about one of the most important physicochemical changes in our water resources: the rise in their turbidity parameters. For freshwater bivalves, changes in water turbidity have a significant impact because they are filter feeders and depend on stable water conditions to regulate their physiological functions. Our preliminary studies have already demonstrated Corbicula fluminea`s (Müller 1774) intolerance to increases the turbidity of the water. In the current paper, we conducted research in the watersheds of the Pardo and Mogi rivers (State of São Paulo - Brazil). Under laboratory conditions, we did not observe statistical differences in the mortality rate of C. fluminea to turbidity levels of 150, 200 and 250 nephelometric turbidity units (NTU). Mortality rates of approximately 50% were observed when the specimens were exposed to these conditions for 96 to 120 hours. Results indicate that the species is sensitive or even intolerant to changes in turbidity, caused by suspended sediment, which explains the high mortality and the seasonal decline in the population of this species during rainy periods. The methodology used in this research, supported by the results produced, may indicate a new way of studying the decline of molluscan biodiversity that has been observed throughout Brazil.
