Animal Fish Family: Cyprinidae Classification: Regulated
a common cold water aquarium fish that have been widely introduced throughout
the U.S. via aquarium dumping. After a few generations revert to something
very closely resembling the crucian carp. The primary threat is probably
competition for food and other resources. Other threats may include the introduction
and persistence of parasites, such as Lernea sp., that commonly occur on
goldfish. As with carp, we do not want any new introductions, and would like
those that are caught by fishermen to be destroyed.
