CATDOLL : CATDOLL: How much oxygen is needed per day for pure oxygen fish farming?

1. What is the daily oxygen consumption for pure oxygen fish farming?

You didn't say how many fish there were, or how big the tank was or how much water there was.

And generally there is no need to use pure oxygen~~ The oxygen from the filter is enough~~

2. What is the oxygenation of the koi fish tank?

Theoretically, it means reaching the maximum value of dissolved oxygen in water. In practice, it means turning on all the oxygen supply and filtration equipment you can use to provide uninterrupted oxygen supply.

3. Do Koi need oxygen?

Adequate oxygen equipment is required.

Like goldfish, koi are not very demanding about water temperature and water quality. The suitable temperature range is 2℃ ~ 30℃, but they cannot resist sudden changes in water temperature. Koi will feel uncomfortable if the temperature difference suddenly exceeds 2℃ ~ 3℃. The optimal water temperature is 20℃ ~ 25℃. They need sufficient oxygen and are suitable for living in a slightly alkaline, low hardness water environment.

Koi is an omnivorous fish that can eat general mollusks, fragments of higher aquatic plants, benthic animals and even tiny algae or artificial synthetic granular bait. You should choose fish that are healthy, without injuries, scales and other diseases, with shiny bodies, diverse colors and clear boundaries.

Check your swimming style:

When koi are healthy, they will swim in all directions. Sick koi will swim alone. When the disease is serious, they will stagger and shake, and may even not have the strength to stop swimming and hit the wall of the pool.

If koi fish form a circle in a corner of the pond or rub their bodies against the pond wall or bottom, it means that the fish have parasites attached to their bodies. In serious cases, the koi fish will rub their bodies, flap their dorsal and pectoral fins, or jump. If koi fish swim with their dorsal fins erect, it is generally a sign of a neurological disease. If koi fish swim in a zigzag manner, it is a sign of abnormal koi fish.

Floating motionless on the water surface is a danger signal, and being unable to stand upright is a condition of loss of balance. There may be a problem with the swim bladder or parasites in the head. When the disease is serious, the koi will swim randomly.

4. How to use sodium percarbonate in koi farming. Can I add it to plastic bags to transport fish?

On rainy or hot days or when water supply is difficult to obtain, dry-spread sodium percarbonate granules to enhance bottom oxygenation.

1. Adjust the temperature and adapt to the water quality

1. Put the Koi fish and the packaging bags into an isolated pool or aquarium. When the Koi fish are packaged, the fish dealer will use 2 or 3 layers of plastic bags and fill them with pure oxygen. After the Koi fish arrive at home, do not rush to unpack the Koi fish and put them into the fish tank. You should remove 1 or 2 layers of plastic bags and only keep the last layer of plastic bags. Let it float in the isolated pool for 40 minutes to 1 hour. During this period, if you find that there is a lack of oxygen in the bag, you should add oxygen again and turn the bag every ten minutes.

2. Open the bag and fill it with 0.3% salinity pond water, which is 1/3 of the original water volume. After adding oxygen or air, tie the bag tightly and soak it for 10 minutes. Before putting the fish in, add coarse salt to the pond water. The increase in salinity needs to be gradual. Generally, 0.3% salt is added first, and then it is increased to 0.5% after 12 hours, and finally increased to 0.7% after 24 hours.

2. Fish disinfection and medication

1. After 10 minutes, when there is no temperature difference between the water inside and outside the packaging bag, take out the fish and put them into 20PPM potassium permanganate water for 2-3 minutes of disinfection. Then put the fish directly into the isolation pool and discard the water and plastic packaging bag in the original bag.

Even koi that look very healthy have some pathogens. The commonly used disinfectant is a 20PPM potassium permanganate solution, which is used to bathe the fish for 2-3 minutes. This disinfection method can effectively kill bacteria on the surface of the fish and on the gills, and prevent pathogens from entering the isolation pool. If obvious injuries are found in some parts during this period, special treatment should be carried out, such as applying medicine, injecting antibiotics, etc.

2. Observe for half an hour. During this process, some koi will jump because they are not used to the existing pond water. Generally, after 30-60 minutes, the jumping will stop and they will swim steadily.

Antibiotics: You can choose water-soluble antibiotics (such as penicillin, erythromycin, etc.) and spray them evenly throughout the pool. Use the dosage according to the instructions.

Sprinkle water-soluble vitamin C evenly throughout the pond for 3 consecutive days, using the dosage as described in the instructions. Vitamin C participates in a variety of physiological processes in koi, and is very important for maintaining the normal growth of koi and enhancing their resistance to stress and pathogens. In particular, its effectiveness in improving koi's resistance to environmental stress and pathogens has been widely recognized, and has achieved good application results in practice. It is an important drug for combating stress reactions.

5. Does it take a long time to oxygenate Koi water?

Generally, fish tanks require oxygenation for 24 hours. The same is true for brocade fish, which need longer oxygenation because they are larger. This is just my opinion.
