    California Non-native Estuarine and Marine Organisms Database (Cal-NEMO) [ds503]

    Metadata Updated: November 23, 2025

    The data provided is from a database known as Can-NEMO (California Non-native Estuarine and marine Organisms) database. The Cal-NEMO databaseincludes 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.The data provided from Cal-NEMO to BIOS includes the introduced species name and location, date observed, and habitats observed.Cal-NEMOincludes species lists and other associated information for both non-native and native coastal aquatic species in California. New records are being added continually, and existing records are frequently updated and modified as new information becomes available. Cal-NEMOis an accumulation of literature review, data collected by other entities, and OSPR field surveys. OSPR began surveying in 2000 and continues to monitor for new introductions. Records before the year 2000 are from literature review and surveys by other entities.
