Welcome to aquatic_introductions! This listserv is for interactive information sharing and support in preventing, containing, and managing introductions—authorized or not—of all aquatic species. Any member of the Introduced Fish Section of the American Fisheries Society is welcome to join, as are AFS officers and staff and—by invitation of moderator—interested persons from related fields such as policy development and aquatic-plant research and management. A primary objective of this listserv is to discuss and execute business of the Introduced Fish Section. However, we welcome and encourage the active participation of all our list members.
