The growth, morphological changes, organ development, and regeneration of severed limbs are inseparable from the miraculous process of crayfish, a member of the crustacean kingdom of aquatic animals. The carapace of the crayfish is like a strong castle, and the building material of this castle is the indispensable calcium.
Imagine that when the calcium in the lobster's body is sufficient**, just like the architect has enough building materials, the strong castle can rise from the ground faster, and the speed of molting will naturally increase. Not only that, but the fortification of the castle will also be enhanced due to the high quality of the materials, which will increase the success rate of molting. What's even more surprising is that after the completion of the castle, the individual size of the crayfish will also increase, showing a more robust body.
However, if there is not enough calcium in the lobster's body**, like a shortage of materials in the hands of an architect, that strong castle cannot be built smoothly. At this time, the lobster may have a loss of vitality, and even the medium and large prawns will face the threat of death. Therefore, calcium is undoubtedly an indispensable and important element in the life of crayfish.
As can be seen from the above table, in the pond where the calcium hardness is maintained at about 80mg L and the total hardness is about 100mg L, the lobster has excellent vitality, and the phenomenon of weakness to lie on the edge rarely occurs. When the calcium hardness drops to about 40mg L and the total hardness is about 60mg L, the activity of lobster is significantly reduced, the incidence is serious, and the phenomenon of inability to lie on the side is particularly prominent. Exogenous water calcium is generally 11040mg L, and the hardness is about 150mg L. These data fully prove that the consumption of calcium ions during the growth of lobsters is extremely high. Insufficient calcium ions will lead to problems such as soft shell and failed molting of lobsters, and even weakness and lying on the side in severe cases.
