The correct method for raising fish in sea salt
1. Kill pathogenic bacteria or parasites.
Salt is a bactericidal disinfectant and insecticide, and its aqueous solution can be used as an osmotic agent to change the Osmotic pressure of pathogens or their attached organisms through immersion, so that they lose balance and die of salt or fall off, mainly to prevent bacterial, fungal or parasitic diseases. In terms of feeding and management of koi, salt can be used to expel white spot worms and treat rotting tail disease, rotting fins and other rotting diseases or Hypersomnia.
2. Reduce and adjust the Osmotic pressure of koi.
Due to the influence of Osmotic pressure, the water of the koi often seeps into the body, so it must be discharged from the body. The function of keeping fish water in equilibrium is called "Osmotic pressure adjustment function". Koi carp continuously urinate, which means they are excreting water, indicating good kidney function. If the koi gets sick, its urination function will decrease, and the burden on organs such as the kidneys will be greater. Therefore, if the salt content in the fish pond is close to that in the carp's body, the water in the pond will not penetrate into the carp's body, and the carp will not urinate, thus reducing the burden on the kidneys. Therefore, fish friends should strictly follow a 0.5% salt ratio when the koi is sick.
In a word, adjusting the Osmotic pressure of water by adding salt can reduce the penetration of water into fish, prevent the spread of viruses in water, reduce the burden on kidneys, reduce the pressure on the osmotic system and improve immunity.
So how do you use salt?
1. Salt is only necessary when the koi is sick and needs treatment. If salt is added every time the water is changed, it will reduce the osmotic regulation ability of koi carp, and the effect of adding salt will be greatly reduced when they get sick.
2. It is best to use crude salt or aquarium specific salt when using salt, and seasoning salt containing additives, such as iodized salt, cannot be used. The salt should be dissolved in advance and filtered roughly before use. The salt concentration should be gradually increased within 1-2 days to avoid the Osmotic pressure shock of koi.
3. When the salt concentration reaches 0.3% -0.5%, it can play a role in regulating Osmotic pressure. This concentration is safe for the vast majority of fish. In addition, excessive salt use will cause excessive Osmotic pressure, which will further lead to physiological changes in the body cells of koi, and will lead to a decline in the resistance of koi to disease. When the salt concentration exceeds 1%, even short-term soaking can cause adverse reactions to the fish, so it is important to be cautious in determining the amount of salt added.
4. Adding salt can reduce the negative effects of temperature rise. Although temperature rise can accelerate bacterial reproduction, the Osmotic pressure of water after adding salt decreases, which can prevent bacteria from entering the fish body to the maximum extent. Therefore, temperature rise and salt fall are complementary.
