The Cal-NEMO database includes comprehensive and user-friendly information on established non-native invertebrates and algae in the marine and estuarine waters of California. A collaboration between Office of Spill Prevention and Response (OSPR) and the Smithsonian Environmental Research Center (SERC), Cal-NEMO is a portal of the National Estuarine and Marine Exotic Species Information System (NEMESIS).
Cal-NEMO replaces CANOD, OSPR’s inventory of non-native species in California. Improvements include images and descriptions for identification, maps of global distributions, and information about species ecology and impacts. It is a long-term, dynamic database that we will continue to update as new species are discovered and new research becomes available.
