Koi carp

Did you know?

Almost two thirds of households near our waterways are disadvantaged. Support our community projects along canals and rivers.

Koi carp (Cyprinus carpio) are genetically the same fish as the common carp.

Typical weight: 2-10lb

Lateral Line scale count: 33-40 (this is the dark row of scales along the central length of the fishes body).

Lifespan: up to 45 years

Koi carp were originally introduced to Japan as a food source. Fish farmers identified fry exhibiting slightly different colourations and markings. These fish were then selectively bred over generations to produce the beautifully coloured and marked fish you see today in pond keepers and specialist Kio dealers. They are not generally thought of as a fish anglers would catch. Fish caught in ponds, rivers and canals are likely to have been illegally introduced.
