| Comments: | Recorded from the North I, widespread only in the north but range is expanding (Ref. 52336). Designated a noxious fish but sought after by specialist anglers. Presence of localized populations in ponds and farm dams. Although reported to have been introduced in early consignments of fish there is no evidence of long term presence prior to 1960. New Zealand stocks are derived from ornamental Japanese koi variety imported by aquarists in 1960's and released or escaped to the wild. They are widely established in the lower Waikato River and associated lakes as well as ponds around Auckland and Taranaki. Their bottom feeding habits generate turbidity and by uprooting vegetation may alter plant communities. Such damage has not been great in New Zealand where efforts are being made to contain their distribution (they are designated noxious under the Fisheries Regulations) (Ref. 13730).
