Aquatic farmers know that the hardness of the water body is very important, not only for the conversion of organic matter, but also for reducing the toxicity of toxic substances (heavy metals, hydrogen sulfide), but also for the growth and development of algae and prawns. The hardness of water refers to the content of divalent and multivalent metal ions in the water, including calcium, magnesium, iron and so on. Therefore, to maintain the hardness of the water body, it is also a good choice to use feed grade calcium formate to supplement calcium ions.

First of all, if the water body's hardness is insufficient, the prawn's shelling and solidification physiological activities will be hindered. Therefore, it is difficult to shell and soft shells, which are one of the main reasons for the morbidity of prawns. Shrimp need calcium supplementation to resist stress.

The role of feed grade calcium formate:

1. Calcium supplement: organic calcium with high calcium content can absorb quickly by shrimps, crabs and mussels, promote molting and hard shells. After use, shrimp and crab shells are smooth and shiny, which enhances physical fitness.

2. High-energy supplementary nutrition: It is rich in high-energy nutrition necessary for shrimps and crabs to quickly restore the physical fitness of aquatic animals, restore physical fitness, and promote molting. 

3. Enhance the anti-stress ability: small molecule organic calcium, shrimp, crab, mussels, etc. absorb quickly, promote molting and hard shells, after using calcium formate, shrimp and crabs are smooth and shiny, and strengthen physical fitness.

Shrimp shelling needs to consume several times more dissolved oxygen and energy than usual, and needs to absorb highly soluble calcium, magnesium and phosphorus from the water body in time to promote the hard shell. Otherwise, there will be sequelae of shelling, and it is easy to be stressed and even die.

To improve the quality of prawns and other aquatic products requires calcium supplementation. Feed grade calcium formate has a good effect on animal bones, crustaceans, scales, etc. It has a good effect on protein synthesis and metabolism, carbohydrate conversion, cell permeability, and chromosome structure. And functions have important influences. Regular calcium supplementation can make the crustaceans of the prawns bright and clean, with good body color, and improve the quality and appearance of the prawns.
