Filopaludina maekoki has been assessed as Least Concern. This was one of the most dominant species found in a recent survey of Ubolratana reservoir, northeastern Thailand, and it appears to be a habitat generalist. Further research however is recommended into the threats facing this species as a result of the ongoing dam construction projects for the Mekong.

Threats [top]

Major Threat(s):

Until the 1980s the Mekong River flowed freely for ca. 5000 km from its source in Tibet to the coast of Viet Nam. The Mekong River passes through or by China, Myanmar, Lao PDR, Thailand and Cambodia. But since the 1980s the character of the river has been steadily transformed by dam-building programs in Yunnan province in China. Three hydroelectric dams are already in operation and two more are under construction due for completion in 2012 and 2017. Until 2030 there could be plans for at least two more dams. There are also eleven proposed dams on the mainstream of the Mekong below China. Even if no dams are built on the mainstream below China the dams in China will ultimately have serious effects on the functioning of the Mekong. It will alter the hydrology of the river and so the current "flood pulse", the regular rise and fall of the river on an annual basis. The dams will block the flow of sediment down the river which plays a vital part in depositing nutrients on the agricultural regions flooded by the Mekong River. The dams will also lead to the erosion of river banks (Osborne 2009). Although the ecological effects of these dams on freshwater snails are poorly known Temcharoen (1992) mentioned a negative effect on the snails caused by irregular fluctuation of the water level.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for this species. Further research is recommended into the impacts of dam construction on this species.
