Can sodium thiosulfate be used in crab ponds in low temperature weather?

Sodium thiosulfate can be used in crab ponds in low temperature weather. Sodium thiosulfate is a commonly used water quality improver in aquaculture, which can lag behind various toxins, heavy metals and residual chlorine in water. There is also a water purification function. However, it should be noted that it cannot be used in high temperature period, which may easily lead to hypoxia and crab death. Sodium thiosulfate is mainly used to remove pesticide residues, heavy metals and chlorine-containing preparations.

Breeding method of crab

In breeding places, crabs are suitable for growing in ponds with convenient drainage, sufficient water and good water quality. The water depth shall not exceed 1.5m, and the soil in the pond must be sandy soil with good air permeability and rich humus, which can provide natural bait for crabs.

Disinfection measures: before stocking crab seedlings, the pond must be disinfected, and after exposure, it can be disinfected with quicklime. Zucchini and Sophora alopecuroides can be planted in the pond, which can not only provide food for crabs, but also purify the water.

Reasonable feeding, crabs eat aquatic plants and microorganisms in the pond, basically relying on artificial feeding, such as potatoes, fish and shrimp, wheat and so on. And it is best to do it at night. In addition, it is necessary to clean up the residue at the bottom of the pond in time to prevent water pollution and make crabs infected with pests and diseases.

Increase oxygen. Crabs belong to amphibians and have a great demand for oxygen. In the process of breeding, aerobic equipment should be put in the pond to prevent the crab seedlings from appearing bad phenomena in the water, making their shells soft and fall off, and in severe cases, they will die.
