Title: Database on Introductions of Aquatic Species (DIAS) from the UN Food and Agriculture Organization (FAO)
The Database on Introduction of Aquatic Species (DIAS) contains
information on introductions of freshwater and marine fish, molluscs
and crustaceans. It is produced by the Fisheries Department of the
Food and Agriculture Organization (FAO) of the United Nations.
The database includes records of species introduced or transferred
from one country to another and does not consider movements of species
inside the same country. Coverage of accidental introductions of
organisms (e.g., through ship ballast waters) is not complete and
records on this topic have been generally entered only when important
impacts on fisheries or on the environment have been caused.
In light of the international interest in introduced species by groups
such as the Convention on Biological Diversity, NGO's and the private
aquaculture sector, this database represents an important source of
information on both the benefits and risks of species introductions.
The following information is potentially available in the database for
each introduction event:
Genus and species name
Country introduced to
Country introduced from
Year of introduction
Reasons for introduction
Establishment of introduced species in the wild
Method of establishment of species
Use as aquaculture species
Type of ecological effects
Type of socio-economic effects
Users aware of other introductions of aquatic species not already
included in the database or that have additional information on the
records in the database are requested to fill in the Input Form.
