Koi have been a foundation for water gardens across the globe for almost two hundred years. The earliest records suggest that rice farmers in Japan noticed that some of the carp growing in the rice fields were more colorful than others. Soon the farmers began capturing distinctively colorful specimens and raised them for breeding purposes. Believe it or not, Koi are actually a hybrid species of the common carp!
Variations
Koi come in a number of varieties, each with different sizes and color patterns. Koi are generally limited to the major colors of orange, black, white, red, yellow, and blue, but can have any combination of these colors in a given fish. It takes a trained breeder to spot the subtle differences that can account for deviations between some species.
Habitat
Koi are extremely resilient fish which no doubt contributes to their enormous popularity in home water gardening. They can withstand a wide array of temperature fluctuations and water qualities. However, in warmer climates, Koi prefer deeper water to get away from summertime heat. Likewise, in severe winter ranges, Koi generally need to be kept in ponds with a depth of at least one meter.
Many Koi ponds are self-sustaining for the fish, meaning they rarely need to be fed as a result of natural vegetative and animal matter that may build up in the pond. Still, many owners choose to feed their Koi formulated Koi feed which supports rapid growth and healthy immune system function in their fish.
Protecting Your Koi
To many Koi collectors, the fish symbolize not only a time investment, but a financial one as well. Specific varieties of Koi may fetch anywhere from several hundred to several thousand dollars on the open market. As a result, special measures should be taken when preparing or improving your existing Koi pond to protect them from opportunistic predators.
A Koi pond should have several deep areas to allow the Koi to retreat in the event that a hungry heron should make a stop in your pond. Likewise, plant material such as Water Lilies can be used to supply a safe hiding place. Pond netting can be implemented in extreme cases where fishing birds remain a persistent problem. Also, any ledges or walls around the pond should be high enough from the surface to prevent a hungry cat or raccoon from making a snack out of your beloved Koi.
Koi Wrap Up
Raising Koi is a unique and rewarding experience at the very least and can add color and life to any water garden. They are forgiving fish, which can bear a degree of neglect, making them the perfect pond pet. Don’t hesitate to contact your local pond supplier for details on starting your own Koi pond today!
