Artificial seawater and a preparation method thereof

The invention discloses artificial seawater and a preparation method thereof. The artificial seawater comprises the following components in parts by mass: 50-70 parts of crude salt from Yuncheng saltponds, 10-25 parts of magnesium sulfate heptahydrate, 10-20 parts of magnesium chloride hexahydrate, 1-5 parts of calcium chloride, 0.1-3 parts of potassium chloride, 0.01-1 part of sodium bicarbonate, 0.01-1 part of sodium carbonate, 0.01-1 part of microalgae and 0.01-1 part of probiotics. The raw materials of the artificial seawater, i.e., the crude salt from Yuncheng salt ponds and the magnesium sulfate are derived from Yuncheng salt lakes, and other raw materials are wide in source, low in price, simple and convenient in preparation method. The artificial seawater is widely suitable for mariculture, especially for seawater ornamental fishes. Through multiple feeding tests of ornamental fishes such as blue snapper, clownfish and the like, the survival rate can reach 96.6%. 本发明公开了一种人工海水晶及其制备方法，按照质量份数包括：运城盐池大盐50～
