Hyriopsis Schlegeli Cumingi
----Common Name: FRESH WATER PEARLS
Although the Japanese freshwater pearl industry has nearly ceased to exist, it holds special historic value as the first country to cultivate whole freshwater pearls in Lake Biwa, using the Biwa pearly mussel (Hyriopsis schlegeli). The industry attempted a comeback with a mussel hybrid (Hyriopsis schlegeli/Hyriopsis cumingi) in Lake Kasumigaura in the last decade, but this venture also met with failure, with production ceasing in 2006. The pearl farm in Tennessee also holds special historic value as it is the only freshwater pearl outside of Asia, founded by the late John Latendresse, it continues as a tourist attraction. Today China is the only commercial producer of freshwater pearls, producing 1500 tons (2005) [1] using the triangle shell mussel (Hyriopsis cumingii) and several hybrids that have shown heterosis from several mussel species.
