Age determination of brocade carp

1. If you want to get the right age, you can see from the rings on the fish scales that the rings are similar to trees in shape, but you have to look at them with a magnifying glass or microscope, and the new scales are not accurate. All fish in this part are the same.

2. if you only roughly estimate whether the fish is old or young, you should look at its eyes. Generally speaking, the fish of the same size have larger eyes, lighter and older eyes, and the black part of the fish eyes is older.

3. Koi has more body color performance, generally mature fish, the stability of body color texture is higher and more solid.

Koi has a wide range of food habits, is omnivorous fish, reproduction is also very easy, the method is the same as ordinary carp. However, to cultivate a very high-quality "Ming carp" is a goal that many ordinary farmers dream of achieving. In the past, as producers of koi, they all paid attention to how to produce more fish fry and commercial fish, but felt at a loss about how to improve the quality of products and the rate of high quality, although some also carried out so-called selection, but because they failed to master the real selection technology, they left those who should be eliminated and eliminated those that should be left behind, so they got very little results. As a result, a lot of inferior products were produced. It not only wastes time, water and feed, but also doesn't get the benefits it deserves.

At present, in the domestic market, a koi of about 20 centimeters in that year can be sold for thousands of yuan if it is a high-quality product, and the price of a grade A product is more than 100 yuan, while the overall price is 3-5 yuan per tail, and the lower product is 6-20 yuan per kilogram. In the international market, the price of fine goods can reach more than 20,000 yuan. It can be seen that in the same farming area, using almost the same feed, the results of careful selection and non-selection are very different.

The method of selecting and purchasing koi

1. Health: no matter what kind of fish you buy, you should choose those that are flexible in swimming, active in eating, well-proportioned and strong, with wide shoulders, thick mouth and strong tail handle. Among other things, as long as you are in good health, the process of raising will be able to reduce the troubles of disease.

2. Body color: whether the koi has excellent genes, body color is the most direct embodiment, while the body color of koi requires only strong and bright color, white should be pure and warm, crimson should be as bright as blood, and ink should be thick and not scattered.

3. Pattern: different varieties of koi have been clearly emphasized, for example, the color of the nose is not lower than that of the eyes, the ink of Dazheng is not on the head, and Showa must have noodles cut and so on.

4. Somatotype: koi should have a smooth figure and have a good figure in order to have a good swimming posture. Generally, they first look at the head, then look at the performance of the tail of the koi, and finally look at the overall performance of the body of the koi.

Feeding methods of koi

1. Water quality management: koi is not strict on water temperature and water quality, so it is suitable to live in a slightly alkaline and low hardness water quality environment. However, as the saying goes, "raise water first", so do not underestimate the water quality. You should know that most diseases of koi are caused by poor water quality.

2. Water temperature management: the range of water temperature for koi is 2: 30 ℃, and the most suitable water temperature for life is 20: 25 ℃. In this temperature, koi swim actively, have a strong appetite, have a strong physique and have bright colors.

3. Breeding density: koi should pay attention to the density when raising koi. Generally, 6 koi with a length of 15 cm, 8 carps with a length of 90 × 30 × 50 and 10 carps with a length of 110 × 30 × 50 cm can be raised in an aquarium with a length of 60 × 30 × 15 cm.

4. Feed feeding: koi is similar to goldfish in feeding, and can be fed twice a day. Depending on the increase or decrease of temperature in different seasons of each year, fish and insects, pellet feed, small earthworms and other bait can generally be fed, but should they be fed too much? generally, 80% can be full.

5. Prevention and treatment of fish diseases: common diseases of koi include water mildew, Gill rot, enteritis, vertical scale disease and so on. Attention should be paid to the administration of corresponding drugs to improve the disease. Although brocade carp disease is inevitable, it is still recommended to do a good job in the prevention of brocade carp disease.

6. Management of the four seasons

① spring: the weather is warm and cold again, koi begins to recover from hibernation, should be transferred from indoor to outdoor, but should pay attention to sudden cooling, timely cover film, keep the water temperature stable. The bait was mainly plant bait, and the amount of bait increased gradually.

② summer: the weather is hot and hot, so it is most suitable to cover with plastic shading net to prevent direct sunlight, so that the sunshine intensity can be reduced from 8000 lux to 5500mm 5800 lux.

③ autumn: the weather is less rainy and more sunny, and the water temperature decreases obviously, which is the most suitable for the growth of brocade carp, which can increase the proportion of animal protein, such as silkworm pupa. Increase the amount of investment to promote fast growth.

④ winter: the weather is relatively cold, when the temperature drops to 0 ℃, the koi should be transferred to the indoor fish pond in time to overwinter, and the indoor water temperature should be kept at 2: 10 ℃. Proper bait should be used to keep fat and prevent disease.
