to use salt when the

fish is injured? It is useless to use salt when the fish is injured. Although salt can play the role of sterilization, but there are certain requirements for the concentration, the concentration of salt for fish can not reach the standard of sterilization, up to five thousandths, so the effect is very limited, if you want to treat, you still need to use yellow powder and other drugs to sterilize, at the same time, pay attention to water warming, so that you can recover slowly. In addition, in the process of feeding, fish should be prevented from being injured, and those who fight should be isolated immediately.

Salt

is usually used only when the fish is sick. Adding salt to the water can increase the osmotic pressure of the water body. In this way, it can reduce the infiltration of water. If there is less water entering the fish body, the bacteria will naturally be less, thus hindering the invasion of bacteria.

2. Reduce the burden on the kidneys: As mentioned above, adding salt can reduce osmotic pressure, thereby reducing water ingress. Freshwater fish need to drain water through the kidney because of the continuous infiltration of water. If the infiltration of water is less, the drainage will be less, thus reducing the burden on the kidney.

3. Sterilization and disinfection: Salt can also play a role in sterilization, but the concentration should reach about 1%, and this concentration of salt water can not soak fish for a long time, only a few minutes, a long time the fish will show discomfort, and even endanger its life.
