The scientific literature on molluscans taxonomy in Iran goes back to many years ago; however, in some parts of the country like southern areas, it is completely new. In addition, many of the studies have focused on their potential risk as intermediate hosts for parasites, ignoring their specific taxonomic identification or detailed ecology. In this research, molluscan fauna of Jubkhalle River, southern Iran was investigated in five stations during 2015 and 2016 within a span of 13 km. Four species from gastropods including Physa acuta, Planorbis intermixtus, Radix persica and Galba truncatula as well as a bivalve species Pisidium casertanum were identified. Among them, R. persica and P. casertanum were new records for the Fars Province. Our results showed consistencies between the number of species present and their environmental settings including total dissolved solids, electrical conductivity, and the water current velocity. Mean annual current velocity was lowest in station 2, having the highest temporal fluctuation, while total dissolved solids drastically increased in lower reach (stations 4 and 5), with the lowest fluctuations.
