Most of the water used for fish farming is tap water, which usually needs to be dried before it can be used. Untreated tap water contains residual chlorine, which is harmful to fish and may even cause their death. In addition to drying, some chlorine removal drugs can also be used to purify water, but the dosage must be controlled to avoid excessive harm to fish.
Usually fish need to be fed, but not too much, otherwise it will break its stomach, causing the fish to suffer from enteritis, if not treated in time, it will die. Usually you can feed 1-2 times a day, each time to feed seven or eight full, so that the fish have a certain appetite, so that they are not easy to get sick.
Whether the fish are well raised mainly depends on the water quality. If the water quality is too bad, it will also lead to the death of the fish. Usually, change the water every once in a while to improve the water quality, and pay attention to cleaning up the residual bait and dirt at the bottom of the water when changing the water, so as to avoid rapid deterioration of the water quality.
Lack of oxygen in the water is also an important cause of fish death. This is mainly related to the water treatment method, if the water is heated in order to speed up the dechlorination, although the chlorine will volatilize, but the dissolved oxygen will also be reduced, which will lead to fish hypoxia. Of course, in addition to the correct drying water, but also through the oxygen pump to oxygen.
