KOI

Koi are ornamental domesticated fish bred from wild Amur carp (Cyprinus rubrofuscus), originally developed in Japan over 1,000 years ago. Known for their brilliant colors and graceful swimming, they’ve become icons of peace and prosperity in Eastern culture. However, in the wild, koi can be a problem — escaping or being released into natural waterways where they act much like the invasive Common Carp.

When koi make their way into rivers and lakes, they stir up sediment while feeding, uproot vegetation, and compete with native fish for food and space. Though beautiful, wild koi can become surprisingly large and strong, offering a unique fishing experience for those targeting urban waterways or warm ponds.
