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.
Caridina cantonensis is a species of small freshwater shrimp native to southern China. This species is popular in the aquarium trade, and many different colored varieties have been selectively bred from the wild type shrimp. Despite its presence in the aquarium trade in the United States and elsewhere, it has never been documented as introduced outside of its native range. Further research is required to determine potential impacts of introduction in the U.S. Climate match to the contiguous U.S. is medium. Certainty of this assessment is low and overall risk assessment category is uncertain.
