CATDOLL : CATDOLL: How long does a koi usually live?

What is the average lifespan of a koi?

The lifespan of koi can reach 60-70 years, while the lifespan of koi raised at home is about 25 years. The specific lifespan is related to feeding management and other aspects.

The reason why koi can live so long is that this fish is similar to carp, has strong adaptability, and is larger in size. Generally, large fish have a longer lifespan.

When raising koi artificially, you must pay attention to keeping the water clean and hygienic, which will also help prolong their lifespan. Daily feeding should mainly consist of animal feed, and appropriate light should also be provided.

Things to note when raising koi

1. Water quality: Water is as important to Koi as air is to humans. Good water quality can promote the growth of Koi. Generally, in order to maintain good water quality, you need to change the water about twice a week. If the weather is hot and humid, you need to increase the frequency of water changes, three to four times a week.

2. Feeding: Proper feeding can also promote the growth of koi. Koi have no sense of fullness. If you feed them too much, they will easily die of bloating. During the maintenance period, feeding once a day is sufficient.

3. Lighting: If the light for caring for koi is too dark, the growth of koi will be affected. At this time, artificial light enhancement is needed. You can use incandescent lamps or metal halide lamps to supplement the light. Artificial light enhancement means letting lamps replace sunlight to ensure the light needs of koi. When the light needs of koi are met, the beard will naturally grow well.

Carp can live for more than 40 years under breeding conditions. Like koi, their lifespan is very long, 60 to 70 years (it is said that there are koi who are 200 years old).

Carp is a temperate freshwater fish native to Asia. It likes to live in warm lakes or slow-flowing rivers on plains. It has long been used as an ornamental fish or food fish in China and Japan, and is also cultivated as a food fish in European countries such as Germany.

In winter (especially under the ice), it is basically in a semi-dormant state, and its body fat is consumed in winter. In spring, it craves to eat high-protein food to supplement. In late autumn, winter is approaching. In order to accumulate fat, there will also be a peak period of "catching food", and it is also mainly high-protein bait.

Carp is blue-gray, firm, with regular and neat scales. Its feeding habits are the same as those of ordinary carp. It is a typical omnivorous fish, eating both meat and vegetables, and growing fast.

The scattered mirror carp, also known as the mirror carp or three-scale carp, was first introduced from Germany. The mirror carp has a thick body, flat sides, a high back of the head, a small head and big eyes. The scales on the surface of the fish are large and arranged neatly along the edges. There is a complete scale line from the head to the front of the dorsal fin, and some mirror carp have several scale lines on the lateral line.

How many years do domestic koi usually live?

Koi have a long lifespan, generally living around 60-70 years.

1. The life span of koi is not absolute. It is affected by many factors. The specific time has a lot to do with the owner's feeding method. If the environment is suitable and the maintenance is proper, the life span of koi will be longer. If the maintenance is improper and the growth environment is not suitable, the life span will be short. Generally speaking, the best ornamental value of koi is only about 15 years. After 15 years, the koi may still be alive, but the ornamental value will decrease.

2. Koi, the original species is red carp. Red carp, as an ornamental fish, has been very popular in the Ming Dynasty. It is said that koi originated from Guangxi Longzhou koi, Jiangxi Xingguo red carp, Zhejiang Hangzhou golden carp. The classification of koi varieties is mainly based on the different colors and different carp species produced during its development, and is divided into several large strains. Since the history of koi development is relatively short, the offspring it produces are not as genetically stable as other animals, and can only be divided into large strains.

3. About Koi feed. Animal feed is one of the most favorite and nutritious feeds for Koi. There are many varieties, the most common ones are fish worms (bloodworms, water lice), sword water lice, paramecium, and water earthworms.
