OBJECTIVE: the study carried out in Yaguajay, Sancti Spíritus province was aimed at identifying the mollusk species present in the freshwater ecocystems as well as their distribution and abundance in each reservoir.
METHODS: two years--2005 and 2006--were analyzed through 2 samplings per years covering the rainy and the dry season; 20 reservoirs were sampled to determine the present freshwater mollusks. Data were processed by Excelxp and the statistical analysis used SPSS version 8 processor and 4 x 4 contingency tables.
RESULTS: ten species were detected in 2005, being Tarebia granifera the most distributed and abundant followed by Marisa cornuarietis. It was observed that the highest amount of mosquitoes was collected in the rainy season during the two years under study in addition to proving that there was significant correlation between the occurrence of mollusk species and fish in the 20 researched reservoirs.
CONCLUSIONS: Yaguajay municipality exhibits wide freshwater mollusk fauna if one takes into account the 14 identified species of which 4 turned out to be intermediate hosts for fascioliasis, schistosomiasis and angiostrongyliasis. There is close relation between freshwater malacofauna and vegetation.
