(a) the reasons for koi fish's cylinder jump:
1. When the dissolved oxygen in the water is high, koi fish will be highly active and jump into the tank. Otherwise, how can there be a saying that "carp hits the dragon gate"?
2. Eating habits will change. Some koi fish have formed a fixed feeding habit, and they will jump before feeding time.
3. Inadaptation to the new environment. Mainly in the new koi fish.
4. Be frightened. Koi fish is very timid. Generally, when fishing for water, he is easily frightened and jumps up.
5. There are parasites on fish. If the fish has parasites, it will upset the fish and jump out of the tank.
6. The oxygen content in the water is not high. Koi fish likes to jump out of the water in an anoxic environment.
7. The density of fish farming is too high and the space is too small. If the density is too high, koi fish won't have enough room to move and jump.
8. There is too little water in the fish tank. If there is too little water in the fish tank, koi fish will jump because of the lack of water.
9. The fish tank is too full. If the water in the fish tank is too full for koi fish, koi fish will jump out of the tank easily because of his jumping nature.
(2) koi fish fish tank jump prevention.
1. Cleaning and disinfection in koi fish. Generally, before koi fish enters Hong Kong, it is necessary to wash the fish first, and then disinfect koi fish.
2. Add disinfectant or medicated bath. For koi fish who has been infected with parasites in the tank, sterilization water can be added to the fish tank, or koi fish can be given a medicinal bath alone to prevent koi fish from being infected by bacteria.
3. Maintain sufficient nutrient solution. Keep enough dissolved oxygen in the water. If it is cloudy, there is a great possibility of hypoxia and jumping. If necessary, you can buy an aerator and fill it with oxygen frequently.
4. Adjust the breeding density so that the density is not too large.
5. Water supply should not be too little or too full. Usually, the water supply should be placed at a certain water level, neither too low nor too high. The lowest water level is twice as high as the fish, and the highest water level is 5- 10 from the tank mouth.
6. Pull or paste the net.
For koi fish, who is like a fish tank, the most fundamental way for koi fish to jump out of the fish tank is to pull the net or cover it first. As long as the net is pulled or covered, koi fish can get dangerous things after jumping out of the port, but it doesn't mean that as long as the net is pulled and covered, we must find out the reasons for jumping out of the tank and achieve real prevention. However, it is necessary to pull the net and cover it. Don't forget that pulling the net will cause koi fish to jump out of the tank.
(3) koi fish after cylinder tripping is processed.
1. If the fish has just jumped out and is still struggling on the ground, it should be immediately picked up and spun into the original pool water to detect the dissolved oxygen in the water. If the dissolved oxygen is insufficient, it should be oxygenated.
2. If the fish is no longer struggling strongly and its mouth is still open and closed, quickly pour the original feed water into a shallow basin, half of the new water, and use an air pump to make oxygen. At this point, the fish can still breathe spontaneously, and most of them can recover on their own.
