Introduced species, also known as alien species, are a proven
means to increase production and value from aquatic systems. However,
they are also recognized as a serious threat to aquatic biodiversity,
and may disrupt social and economic structures. This CD-ROM provides
information that will assist with the responsible use and control
of alien species in fisheries and aquaculture.

and guidelines are contained in full-text versions.
