Carassius auratus (Wild Goldfish )

Animal Fish
Family: Cyprinidae
Classification: Regulated


Goldfish are 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.
