Interesting, Educational & Fun Facts About Koi Fish & Carp 2021
Carp domestication began as early as the 4th century in China, with modern koi breeding originating in Japan and China several thousand years ago. They descend from the common carp (Cyprinus carpio), and are commonly called “Goi” in Japan, which translates to “carp.” It can also mean “love” or “affection,” with koi traditionally being seen as a symbol of friendship, love, and kindness. The age of koi, as with any fish, can be determined by looking at their scales. Each scale possesses rings called annuli, which resemble the growth rings in trees. Generally, summer annuli are wider and correlate with higher temperatures and greater nutrition, while winter annuli are thinner due to cooler temperatures, decreased activity, and decreased feeding.
