Breeding Koi

Koi, or Nishikigoi, are quickly becoming very popular in the United States, and throughout the world. However, there are still a few discussions as to their origins.

Although it is generally accepted that breeding carp for food originated in China in the 17rh century, the Japanese are recognized as the first to take the naturally occurring mutations and develop them further

After years of selective breeding, various colour mutations started showing up. The first colour patterns were recorded as early as 1805.

Today, there are literally thousands of colour variations available. The most popular colours found are white, silver, yellow, orange, red, black, blue and green. Combined with the patterns available, the possibilities are almost endless.

Each noticeable pattern and colour have their own names, which are typically as unique as the colour they are referring too. Favourite types vary by country and location.   

Koi are raised for purchase in countries like Japan, Singapore, Israel, and in the warmer American states such as Nevada and California. Koi can be purchased at most local pet stores.

Koi are omnivorous fish, which means they will eat both meat and plants. This means that their diets are very versatile. Koi will eat pretty much anything that you put in the pond with them, no matter if it is good for them or not.

Another potential problem is over feeding treats. Again, Koi do not have the knowledge to know when to stop eating, and weight issues may come from overfeeding none nutritional foods.

The healthiest treats for Koi are what they would find naturally in their ponds, such as earthworms and tadpoles, but it will not hurt to feed Koi treats such as Lettuce, bread, fruit, and veggies.

Koi are none-aggressive fish. This means that they are suitable to live with other fish such as goldfish or comets.

The only issue you may find is smaller, less able fish may suffer from lack of food, as Koi are quick and greedy eaters.

Koi are so mellow that they have even been known to be trained to eat out of their owner’s hand. Koi do not have teeth, so you will not get bit if you decide to attempt to feed your Koi out of your hand.

Most fish owners understand that most fish will only grow to the size of their enclosure. Koi, unlike other fish, will grow until they are the size of their specific type no matter the environment that they are in. So therefore it’s important to accommodate the amount of fish reletative to the size of pool.

Baby Koi can be found as small as 3 inches. Jumbo Koi have even been known to reach lengths of three feet or more. The most common size found is around two feet in length.

Koi have been known to live up to 30 years under the right conditions, so if you are thinking about buying Koi, you must consider this. A Japanese Koi, who was 233 years old when he died, holds the record for the oldest Koi.
