The Food and Agriculture Organization (FAO) has compiled this searchable database from data collected in a mid-1990s survey of regional aquatic professionals from around the world. Users can view an input form, add a record to the database, and view the summary statistics. The Statistics link provides summary tables of species introductions; categories include: species, groups of species, continent, year, reason (for introduction), introducer, established in the wild, as aquaculture species, ecological effects, and socio-economic effects. Searches can be based on genus, species, location, reason for introduction, year of introduction and other characteristics. A glossary of terms and links to related sites is available.
