Ecological Risk Screening Summary - Corbicula moltkiana (a clam, no common name) - Uncertain Risk

Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments. This additional information will help inform decisions on where, when, and how the species may be used to minimize risks of them becoming invasive.

Corbicula moltkiana is a freshwater bivalve found in lakes and streams in northern Sumatra, Indonesia. C. moltkiana is found in Lake Singkarak, and Lake Manindjau. C. moltkiana has an uncertain history of invasiveness; it has not been reported in the wild as established outside of its native range. This species is found in trade; it is considered a delicacy in Indonesia and is found in the pet trade. Although C. moltkiana is a popular food item, it carries the pathogen Vibrio parahaemolyticus which can be transfered to humans through consumption and serve as a risk to public health. The climate match for the contiguous United States was generally low with all individual states receiving a low climate score. A slightly higher, but still low, area of match was found in states along the Gulf of Mexico and the southern Atlantic Coast. No georeferenced locations were available to use when selecting source locations for climate matching, so collection locations reported in the literature were used. The certainty of assessment is low. The overall risk assessment for Corbicula moltkiana is uncertain.
