Methods and Techniques of Koi Culture

Grasp the breeding season, the spawning time of koi, and the opportunity to play oxytocin.

After about ten minutes of oxytocin (depending on the performance of the fish), prepare for artificial spawning. The fertilization rate of artificial reproduction is higher than that of natural spawning.

Fertilized eggs should be disinfected, and green water should not be used for hatching water. Incubation water and incubator tanks and ponds should also be sterilized. Put the fertilized eggs into the incubator and put methylene blue into the pool to prevent water mildew.

Grasp the opportunity to take out the fish nest, prematurely will cause seedling death, after the party will cause the growth of bacteria in the water.

Fish fry hatch in two days without feeding, will absorb the nutrients in the yolk, you do not eat

Koi is easy to raise. In spring, summer and autumn, pay attention to the occurrence of bacterial disease, and pay attention to the occurrence of fish scab and scale disease in winter. Fish farming focuses on prevention. Don't wait until you get sick before you treat it. Early detection of abnormalities and early treatment.

From the perspective of ornamental and aquaculture, water is regarded as the soul of landscape. Except for hardness, other water quality indexes of landscape water and aquaculture water belong to the range of surface water standards (a total of 24 water quality indicators), which can be used to culture aquatic animals and aquatic plants to regulate humidity and beautify the environment. Without the circulation of the whole and branch water system of nature, it is impossible for the stagnant landscape water to balance the water quality for a long time. As long as there is one water quality index that exceeds the standard, there is a problem with aquatic animals. Harmfulness of aquatic plants and the environment. Practice has proved that the way to control individual water quality indicators is a temporary mitigation method for temporary relief rather than a permanent cure, and does not solve the fundamental problem of water quality. This shows the overall importance of water quality standards and indicators.

Many consumers do not know the professional standard data they need, but they only need to ask for three purposes. 1. The water is clear. two。 Tasteless. 3. Aquatic animals and aquatic plants can grow normally, which is the standard.

At present, there are about several kinds of water treatment technology products that are common in various countries' markets, such as

(1) Chemical products

(2) activated carbon adsorption products

(3) Live oxygen sterilization products

(4) Biological bacteria products

(5) Sonar acoustic interference products

(6) Optical sterilization products

(7) Ecological filtration and sterilization products

The above water treatment technologies only play a role in alleviating the individual water quality indicators of water quality, and most of them are aimed at bacteria and ammonia nitrogen. In the end, it is necessary to change the water to alleviate the water pollution. There is a fundamental difference between water treatment technology and water purification technology. to put it simply, water treatment technology is a physical and chemical treatment for a single index of water, and the purpose is only to delay some of the water quality indicators exceeding the standard. There is a fundamental difference between water treatment technology and water purification technology. to put it simply, water treatment technology is to deal with some water indexes in physical and chemical ways, in order to delay the substandard treatment of some water quality indexes. Sewage purification technology is the comprehensive treatment of water standards to the scope of the standard. Because there are standard requirements for the use of water, it is very strict in terms of environmental protection and standard requirements. The national environmental standard for surface water quality is accurate to PH. Temperature. Outside the bacteria. The other 21 items are required in milligrams per liter of water (gm/L).

Analysis of water purification products:

a. Domestic water purification technology products; this product is for the purpose of further deep filtration and disinfection of tap water for direct drinking. Because tap water belongs to the standard of domestic water use, the technical content of water re-purification based on this standard should be low. But the manufacturing materials and professional requirements are very strict. Tap water can be completely sterilized when it is physically heated to 90-99 degrees. Reduce hardness and other over-standard objects.

b. Sewage purification technology products; different degrees of sewage will be purified according to the demand of what water quality standards, this is a very high-end technical field. Due to the different pollution sources and pollutants of sewage, the purification technology for it is not simple. However, no matter what purification technology, there must be water quality standards and data standards for various indicators.

Koi is easier to raise, and it is a good choice to raise koi when you are just getting started. If there are conditions, of course, you can change to a large fish tank, plus other supporting facilities. But it also depends on the number of animals raised. It is suggested that group farming should also be determined according to the size of their own fish tank, so that the fish tank can have a good viewing effect. If there is no other supporting oxygen, circulation and other facilities, you can choose to replace 1/5 of the water in the fish tank every 2-3 days, so as to ensure oxygen.

Don't take too much food. Every time you take food to finish it within 5 minutes, you will ok. You can eat once or twice a day.

Feel it slowly, it will be a lot of fun!

Points for attention in common carp culture:

First, koi and goldfish do not have strict requirements on water temperature and water quality, and the range of turbidity of life is 2Mel 30 degrees Celsius. Although it has strong adaptability to the environment, it has the weakness that it can not resist the rapid change of water temperature, such as long-term artificial breeding, the rise and fall of water turbidity is 2 degrees Celsius, the fashion can endure, when the temperature drop or rise exceeds 2 Mel 3 degrees Celsius, the fish is easy to get sick, and when the temperature rise and fall increases to 7 Mel 8 degrees Celsius, the fish crawl on the bottom of the water and do not eat. If the sudden change in temperature is medium or large, it may even die immediately. The most suitable water turbidity for life is 20mur25 degrees Celsius. In this temperature of water, koi swim actively, have a strong appetite, have a strong physique and have bright colors. Control the water temperature that is most suitable for the growth of koi, so that the fish can have a comfortable environment and grow rapidly. Golden carp live in the water by their gills absorbing oxygen dissolved in the water, sending oxygen to the fish and combining the absorbed food nutrients to produce energy to maintain life, so whether there is enough oxygen in the water is the key to raising fish well. the amount of oxygen per kilogram of body weight per hour is 35 mg / L when the water temperature is 5 degrees Celsius, which proves that the higher the water temperature, the greater the oxygen consumption.

Second, the new tank or pool should pay attention to change more water every day, if the water is better, change it twice a week.

Third, pay attention to observe the state of the fish every day. If there is a fish that does not eat or lie in a corner, consider whether the fish is sick.

Fourth, when transferring fish, it is best to use amateur koi to catch the net, and generally use the fairy net. This is not easy to cause damage to the fish.

Fifth, when you see the fish scrubbing, generally, the fish have parasites, so you can consider killing insects.

Sixth, if you see that the water has been relatively muddy, you should consider whether there is something wrong with the filtration system.

When fish are sick, don't rush to isolate them. If isolation is required, there should be an isolation cylinder with a complete filtration system.

Do not buy a large number of koi from different fishing grounds at one time to prevent cross-infection.

9. Some commonly used medicines should be prepared at home, such as crude salt, Japanese yellow powder, potassium permanganate, antibiotics, insecticides and so on.

When buying fish, you should consider the size of your own water body and the efficiency of the filtration system, and the density of fish culture should not be too high.

Happy aquaculture!
