The Common Carp is one of the world’s oldest cultivated fish, bred in China over 2,000 years ago and spread by humans to virtually every continent where it has often become a prolific invasive species. Wild common carp are quite different from the ornamental Koi — which are domesticated color variants — being a more streamlined, brownish fish of turbid lowland rivers. Their extraordinary ability to survive in low-oxygen, warm, and polluted water makes them ecological survivors, but also highly effective competitors that damage aquatic ecosystems where they are introduced.

💡 Fun Facts
01
Carp can survive in water with oxygen levels so low (below 0.3 mg/L) that most fish die, by producing ethanol as a metabolic byproduct instead of toxic lactic acid.
02
A carp's sense of taste is remarkable — it has taste buds distributed not just in the mouth but across its lips and barbels, tasting the substrate before ingesting it.
03
Koi carp have been selectively bred for over 1,000 years in Japan and can live over 200 years; the legendary 'Hanako' koi reportedly lived to 226 years old.
04
Carp do not have a true stomach — food passes directly from the esophagus to the intestine, requiring almost continuous feeding to extract sufficient nutrition.
05
A single large female carp can release over 1 million eggs in a single spawning event, contributing to their explosive population growth when introduced.
