| California: A specimen was caught in Silverwood Lake in 1997. Silverwood Lake in in the Mohave River drainage, east northeast of Los Angeles and north of San Bernardino Mountains. It is believed that the fish got in the lake from the California Aqueduct that runs from the San Joaquin River south of Stockton into Lake Silverwood, one of several reservoirs that serves Los Angeles (Ref. 45309). Florida: Two individuals were also caught in the St. Johns river below Lake Harney, Seminole and Volusia counties in 2000. This species is considered present but not yet established, until reproduction has been confirmed. The species is not involved in the aquarium fish trade but is sold in live food fish markets as a food fish. The most likely pathway is introduction of live food fish (Ref. 53249), perhaps to establish a local market. Maryland: Adults and juveniles were found in a pond in Crofton, Anne Arundel County in late June and early July 2002. New England States: Found in Newton pond, Sudbury, Worcester County, Massachusetts (Ref. 45309). Reported to prey on native fish and amphibians in a number of U.S. states, including Maryland and Virginia (Ref. 51238).
