Embodiment 1

[0019] The present embodiment provides a crayfish ecdysin, which comprises the following components in parts by weight: 33 parts of calcium carbonate, 1.3 parts of vitamin D3, 1 part of magnesium, 0.7 parts of zinc, 65 parts of oligosaccharides and 35 parts of calcium oligosaccharides.

Embodiment 2

[0021] The present embodiment provides a kind of crayfish ecdytic, and described crayfish ecdytic comprises the following components by weight: 50 parts of calcium carbonate, 2 parts of vitamin D3, 2 parts of magnesium, 1 part of zinc, 70 parts of oligosaccharides and 50 parts of calcium oligosaccharides.

Embodiment 3

[0023] The present embodiment provides a crayfish ecdysin, which comprises the following components in parts by weight: 30 parts of calcium carbonate, 1 part of vitamin D3, 0.5 part of magnesium, 0.5 part of zinc, 60 parts of oligosaccharides and 30 parts of calcium oligosaccharides.

[0024] The crayfish ecdytics provided in the above examples are used for crayfish farming. When culturing crayfish, the crayfish ecdytics can be directly sprinkled or mixed with crayfish feed. When the ecdytin is used directly by splashing, add the ecdytic into the water and mix evenly, wherein the mass ratio of the ecdytic to the water is 1:20-50, more preferably, the mass ratio of the ecdytic to the water is 1 :25. When ecdytin is mixed with crayfish feed, the ecdytin and crayfish feed are mixed uniformly, wherein the mass ratio of ecdytin and crayfish feed is 1:800-1100, more preferably, ecdytin and crayfish feed are mixed with The mass ratio of crayfish feed mixture is 1:1000.

Abstract

The invention provides a crawfish unshelling hormone. The crawfish unshelling hormone comprises calcium carbonate, vitamin D3, magnesium, zinc, oligose and oligose calcium. The crawfish unshelling hormone can effectively supplement and keep vitamins and mineral substances needed for growth of crawfish shells and has a good prevention and treatment effect on the phenomena that the shells cannot normally harden, soft shells are formed or crawfishes are unshelled without smoothness, and growth is slow. In addition, the unshelling hormone can adjust calcium and phosphorus balance and promote absorption so that the crawfish shells can be prevented from being soft and thin, being separated from muscles and forming water accumulation, and other bad symptoms can be prevented. Meanwhile, the unshelling hormone can promote chitin and calcium in bodies to be generated according to growth cycles and promote synchronous unshelling, size unevenness is avoided, and the breeding cycle is shortened. In addition, the unshelling hormone has the functions of preventing and treating diseases and promoting appetite. Due to the functions, the unshelling frequency and weight of the crawfishes can be finally effectively increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a crayfish ecdytin. Background technique [0002] Moulting is a very important physiological phenomenon in the life process of crustaceans such as shrimps and crabs. When the larvae have a thin and soft shell, it is called the skin, and the larvae moult mainly undergo metamorphosis, so they are called developmental molts. After entering the juvenile shrimp or juvenile crab stage, moulting is a sign of growth, which is called growth moulting. For crustaceans such as shrimp and crabs to grow, they must quickly shed their cuticles, get rid of their shackles, absorb water or air to grow, extend a new, soft exoskeleton, and then quickly harden the exoskeleton to protect themselves and achieve movement . Ecdysone has the typical properties of steroid hormones, which can stimulate and regulate the metabolism of proteins, sugars and minerals in shrimp, and at the same time can pro...
