Fish out of water will die, the difference is that some fish out of the water to live a little longer, and some will not live so long. Fish live in the water, because their special respiratory organs, gills, can get oxygen in the water, but they lose their function in the air, so they will die out of the water. Generally, carp and crucian carp die within 10-30 minutes after leaving the water, while snakehead can live for about 5-15 hours.
1. Changes in water temperature: We must pay attention to controlling the water temperature in fish farming, especially in tropical fish farming. Once the water temperature changes too much, it will stimulate the fish body, reduce its appetite, and even cause its death. Usually, the water temperature should be maintained at about 20-30 C. When changing water, the temperature difference between new water and old water should not be too large.
2. Too high density: The number of fish to be raised generally depends on the size of the fish tank. If the density is too high, the fish will not only affect each other, but also compete with each other for oxygen. In this way, all the fish will lack oxygen, which can easily lead to the death of the fish. Therefore, it is necessary to control the number of aquaculture according to the size of the fish tank and the size of the fish body.
3. Too much feeding: It is necessary to feed the fish at ordinary times. According to the different feeding habits of the fish, the feed chosen is also different. No matter what kind of feed, do not feed too much, too much feeding can easily lead to fish suffering from gastroenteritis, residual bait will pollute the water quality, which will cause fish death.
4. Disease factors: In addition to the above conditions, fish may also get sick during the growth process, and if they are not treated in time after getting sick, they will also die. Once the fish have signs of illness, need to change the water in time, but also to heat up the salt, if the situation is serious, then take a medicinal bath.
