1. raw materials: sodium chloride 24.72g, potassium chloride 0.67g, calcium chloride 1.36g, magnesium chloride 4.66g, magnesium sulfate 6.29g, sodium bicarbonate 0. 18g, and distilled water is ready. Dissolve various salts in a small amount of distilled water, then add sodium bicarbonate, and finally dilute with distilled water to 1000 ml.

2. Sodium chloride 45.0g, magnesium sulfate 0. 1 g, magnesium chloride 5.0g, ferric chloride 1 g (1% solution). Firstly, magnesium sulfate, potassium monophosphate and ferric chloride were dissolved in a small amount of distilled water, and distilled water was added to 980 ml. Subsequently, calcium nitrate was dissolved in 20 ml distilled water, and the solution was added to the above solution drop by drop, and bottled and stored.

Precautions:

The purpose of sea crystal is to make artificial seawater, which is used for the temporary maintenance of various live seafood products, the propagation of migratory freshwater products and artificial seawater bathing. It is more convenient and economical to use this product than to transport natural seawater.

1, high-purity sea crystals should not be directly added to the existing fresh water solution. It is most suitable to dissolve with clear water first, and then add clear water products after one and a half hours.

2. If the product has caking and deliquescence, its performance will not be affected.

3. The usage ratio is similar to that of natural seawater, calculated as 100 kg of fresh water. For example, crabs and groupers need 3. 1kg, temporary lobsters need 3.4kg, and seafood such as bamboo and shrimp need 2.8kg. The seawater concentration should be appropriately adjusted as needed.

Generally speaking, it takes 24-36 hours to replace the temporary seafood. If the breeding density is high, the water change time can be adjusted appropriately.

5. Artificial seawater used for breeding migratory freshwater products shall be prepared and used in accordance with the technical requirements of aquaculture.
