The correct identification and naming of living organisms is the basis of research in the field of diversity of living organisms and their management. Overexploitation and climate change are causing considerable changes in the diversity of organisms. We are assembling, formatting, analysing published marine biological data, including descriptions, status and environmental data which we will disseminate to a larger number of users. Our aim is to develop a taxon-based biogeography database and an online data server. It will store literature based on taxonomic, and geographical data for species reported from Mauritian Waters. The Database will become a fully functional biological information system which can be updated whenever more data are available. Maps or notes on geographical distribution will be provided in cases where such information is available. The electronic database of Marine Organisms in Mauritian Waters will be linked to existing databases of marine organisms such as Marine Species Database for Eastern Africa (MASDEA), Ocean Biogeographic Information System (OBIS), CephBase and FishBase. The Database will use the World Wide Wed for access and networking, thus making it available to a wide range of end-users. It will be new in its geographical coverage, and in the number and range of taxa that are being considered. This Database of marine organisms will be a standard reference research, management and training in the field of marine species diversity in Mauritian waters.
