Margarya monodi is a species of large operculate freshwater snail, an aquatic gastropod mollusc in the family Viviparidae, the river snails.[3]
This species appears to be endemic to Lake Dianchi, in Yunnan Province, China.
These snails are collected commercially and used as medicine and food.
Threats
[edit]This snail is no longer abundant as it was before the 1980s, when fishermen took as much as 20 kg a day per person. Currently during the open fishing season the fishermen can find only 2 kg a day. In 1999 there were still snails in the eastern part of the lake but by 2009 the snail was found only in the 50 km² of the lake that is near the outflow.
Threats to this snail species' survival include organic and inorganic pollution, overharvesting and some introduced species of predatory fish.
