Amazon Fish Project

-- New -- The Version 2 of the AmazonFish database has been recently released and is freely available

Almost 100 new native freshwater fish species, 200 new sources and 4,000 sites were added to the database

This database, delivered at both georeferenced localities (25,000 localities) and sub-drainages grains (144 units), represents a highly valuable source of information for further studies on freshwater fish biodiversity, biogeography and conservation.

The AmazonFish database


The Amazon Fish database integrates information available in published articles, books, gray literature, online databases, museums and universities. The database is currently updated by including data from more than 100 scientific collections, 31 Partners references, 700 literature references and 5 AmazonFish expeditions . Each record is checked for systematic reliability and consistency, using as nomenclature authority file, the California Academy of Science’s Catalog of Fishes.
A Geographic Information System (GIS), based on the hydrological network and combining the best currently available data sources is linked to the biological database. The GIS includes all major environmental factors meaningful in explaining fish species distribution and related to geographical isolation and habitat fragmentation, habitat diversity, past and contemporary climate, anthropogenic pressures and future climatic projections.
By developing basin wide analyses, the project helps regional conservation programs and contributes to large-scale transnational ecosystem management. The Amazon Fish database is an essential basis for analyzing future trends due to climate change and for helping defining relevant areas of work for the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) at the local, national and regional levels.
