1. Can fish eat salt Fish can eat salt. For fish, the harm of salt is not great, but the dosage should not be too high, otherwise it will have certain influence. Usually, you can't use salt to raise turtles, because turtles can't metabolize salt, so it will cause edema and affect their health after eating. Salt is usually not needed in fish farming, but only when it is sick, and the concentration should be controlled between 0.03% and 0.05%.
2. What's the use of putting salt in fish farming1 to prevent germs from invading: Usually, salt is needed when fish are sick, but the purpose of salt is not for sterilization, because the concentration of salt is relatively low, which makes it difficult to achieve sterilization effect, but it can improve the osmotic pressure of water, so as to reduce water infiltration into fish and germs can not enter.
2. Reduce the burden on kidneys: As mentioned above, salt can change the osmotic pressure, and water will penetrate from places with low osmotic pressure to places with high osmotic pressure, while less water will enter, and less water will need to be discharged by fish, which can reduce the burden on kidneys and help their rehabilitation.
3. Sterilization and disinfection: Although normal salt can't achieve the purpose of sterilization and disinfection, fish can be fished out of the fish tank and soaked in specially prepared salt water. Because of its high concentration, it can play a sterilization effect, but the soaking time should not be too long. If fish are found unwell, they should be put back immediately.
