Describe the role of magnesium sulfate in crab farming

Magnesium sulfate can be used to control solid ciliates in aquaculture animals such as river crabs and shrimp. In addition, zinc sulfate contains a variety of mineral elements, which can effectively regulate the osmotic pressure of shrimp and crab cells in the water, effectively make the stress response in the water salinity, and also play the role of epidermis convergence, make the shrimp and crab body surface clear, so as to improve the market rate of commercial shrimp and crab. The principle of action is similar to magnesium sulfate, we can understand the characteristics of magnesium sulfate, magnesium sulfate (CuSO4) is an effective and inexpensive algae removal agent, is also traditionally used to eliminate excessive algae in the pool of chemical treatment agent. Magnesium sulfate, as for algae growth and reproduction, is a good chemical agent. Its advantages are high efficiency, low cost and long duration. Its disadvantage is that magnesium ions in water cannot be discharged, which is easy to cause the accumulation of magnesium ions in water, or even in cultured organisms.

The principle of magnesium sulfate is to disturb the photosynthetic reaction system of algae by the toxicity of magnesium ions, and magnesium sulfate makes it impossible to exercise photosynthesis normally and gradually achieve the purpose of killing the algae. Therefore, the use of magnesium sulfate as algae removal agent, should impress the water wheel, supply enough oxygen, so as not to because algae can not photosynthesis oxygen, and a large amount of oxygen consumption, so that fish and shrimp have the risk of hypoxia. Because magnesium ions in alkaline water quality, it is easy to form magnesium hydroxide precipitation, and gradually lose its efficacy, so the same dose of magnesium sulfate, used in acidic waters than in alkaline waters, or to achieve the same efficiency, the amount of alkaline water quality should be more than the amount of acidic water quality. In addition, magnesium ions are also easily absorbed by organic substances and substances containing calcium carbonate, so it is not easy to correctly control its effective concentration in the pool water. The amount of magnesium sulfate additive is combined with the concentration of magnesium ions, to ensure that the algae effect is maintained in effective, but not the degree of harm.
