Detailed breeding techniques for koi

Things to note when raising carp:

1. Koi, like goldfish, are not very demanding on water temperature and water quality. The water temperature range for Koi is 2-30 degrees Celsius. Although Koi are highly adaptable to the environment, they cannot resist sudden changes in water temperature. For example, they can tolerate a 2-3 degree Celsius rise or fall in water temperature in long-term artificial breeding. When the temperature drops or rises by more than 2-3 degrees Celsius, the fish are prone to illness. When the temperature rises or falls by 7-8 degrees Celsius, the fish crawls on the bottom of the water without food or support. If the temperature suddenly changes by a large amount, they may even die immediately. The most suitable water temperature for Koi is 20-25 degrees Celsius. In water of this temperature, Koi swim actively, have a strong appetite, are strong, and have bright colors. It is more ideal to control the water temperature to the most suitable for Koi growth so that the fish can have a comfortable environment and grow rapidly. Golden carp live in water and rely on gills to absorb oxygen dissolved in water, send oxygen to the fish body and combine it with the absorbed food nutrients to generate energy to sustain life. So whether there is enough oxygen in the water is the key to raising good fish. The amount of oxygen required per kilogram of body weight per hour when the water temperature is 5-6 degrees Celsius is 35 mg/L. This proves that the higher the water temperature, the greater the oxygen consumption.

2. For a new tank or pond, make sure to change the water more often every day. If the water is in good condition, changing it twice a week will suffice.

3. Pay attention to the condition of the fish every day. If a fish does not eat or lies in a corner, you should consider whether the fish is sick.

4. When transferring fish, it is best to use an amateur koi scoop net, usually a fairy net, which is less likely to cause damage to the fish.

5. If you see a fish rubbing against its body, it usually means it has parasites and you can consider disinfecting it.

6. If you see that the water is always turbid, you should consider whether there is a problem with the filtration system.

7. When fish are sick, do not rush to isolate them. If isolation is necessary, you should have an isolation tank with a complete filtration system.

8. Do not purchase large quantities of koi from different fisheries at one time to prevent cross infection.

9. Some commonly used medicines should be prepared at home, such as coarse salt, Japanese yellow powder, potassium permanganate, antibiotics, insecticides, etc.

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

Happy breeding!

What are the important methods and techniques for breeding koi?

In fact, koi are not difficult to raise. As the old saying goes, people who don't know how to raise fish can also keep koi alive for one to two years. But it doesn't mean that they can be raised in a rough manner. It should be emphasized that koi consume a lot of oxygen. If they are raised in an aquarium or other small containers, the stocking density is high, and an inflator is a necessary equipment. Koi have a lot of excrement, so they should be raised in a bare tank, and a water filter device is also necessary. Koi swim fast and like to jump. Decorations that may cause harm to koi and the fish tank should not be placed in the fish tank, and the container should be covered. The minimum requirement for choosing a fish tank is also 80 cm long (this tank can only hold 2-4 koi of 20-25 cm in size). It would be best if you can use a larger container, of course, because you have to consider the issue of whether the koi should stay after they grow up. But if you don't even have an 80 cm tank now, it doesn't matter. First, successfully raise the fish, and then make plans. To raise koi well, choosing fish is the key. Buying small fish of 10-20 cm in size will have the highest success rate of keeping them alive. When choosing fish, you should check whether the water is too muddy and whether there are a few rotten fish in the fish school. If this is the case, you don't need to look at the fish in this pond. If you pass this test, you can quietly watch the fish you want. Do not buy fish with short and big heads, flat and blunt mouths, skinny or bloated bodies. Choose fish with well-proportioned bodies, active swimming postures, and bright eyes. Cheap fish usually don't have good colors, as the saying goes; you get what you pay for, but their physical condition is still good. After choosing the fish, remember to ask the store to add oxygen to your fish. After bringing the fish home, don't rush to open the bag. Put the entire bag of fish on the surface of the water for 45 minutes to 1 hour to let the fish slowly adapt to the temperature of the water. Then open the bag and let the water in the bag gradually mix with the water in the bag before releasing the fish. In the next few days, the water is most likely to become turbid. It is best to change 1/2-2/3 of the water every day. If your fish tank is too large and it is difficult to change such a large amount of water, you can use a suitable small container to temporarily keep the fish for two weeks. When you see that the fish's condition begins to improve, then scoop the fish into the fixed container. Remember to balance the water temperature of the two containers before scooping the fish. Whether it is temporary or fixed, it is best to put enough activated carbon in the water filter, which is to minimize the amount of harmful substances. After the fish are stable, if you are raising koi in a small container such as an aquarium, depending on the water quality, it is best to change 1/8-1/3 of the water every 4 or 5 days. This is very beneficial to the healthy growth of koi and keeping the water clean. In the whole process of raising koi, it is generally not necessary to add preventive drugs. Blindly applying drugs will only kill the fish. When individual sick fish are found, they should be isolated in time, observed for a few days, and then given the right medicine. When giving medicine, the activated carbon should be removed. The medicine should be light rather than strong. Pay attention to observation. Once the fish have any discomfort, change the water in time. Commonly used medicines include: Royal Fish Treasure Universal Medicine (the main ingredient is methyl blue), yellow powder, potassium permanganate (adjust the bath water to pink). Koi should be fed two to three times a day, and the amount of feeding should be based on the feed being eaten within ten minutes each time. It is recommended that you buy bulk spices (a mixed granular feed, brown with a fishy smell).
