Ecological Risk Screening Summary - Red Goldflake Shrimp (Caridina spinata) - 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.

Caridina spinata is a freshwater shrimp found only in Lake Towuti in Sulawesi, Indonesia. This species has no documented history of introduction or establishment outside of its native range. Wild-caught individuals are available in the aquarium trade. C. spinata has a low climate match with the contiguous United States, with an area of slightly higher match in Florida, along the Gulf Coast, and along the southern Atlantic coast. Certainty of this assessment is low; further information is needed to adequately assess the risk this species poses. Overall risk assessment category is uncertain.
