Koi vs. Carp

Carp Evolution and Mutation: Where Koi and Carp Began

Both koi and carp originate from the Cyprinus carpio species, giving them shared genetic traits. Carp were domesticated over 2,000 years ago for their adaptability, thriving in various environments. Yet, in Japan, genetic mutations were selectively bred for vibrant colors and patterns, leading to koi, or Nishikigoi. These aesthetic and symbolic evolutions distinguish koi from their hardy carp cousins, making koi a cultural icon in Japan and worldwide as ornamental fish prized for their beauty and meaning.
