Problems solved by technology

Since the egg loses the protection of the outermost shell, it is more sensitive to changes in the external environment, and the diapause of the eggs that have been shelled has been released, so the existing storage method of Artemia cysts is no longer applicable and urgently needs to be developed A method for maintaining a high hatching percentage after artemia cysts are shelled and preserved

Embodiment 1

[0017] Taking Kazakh eggs as an example, the hatching of Artemia cysts after shelling and preservation is introduced.

[0018] Three groups of shelled Artemia cysts treated with sodium hypochlorite oxidation and dehulling were taken as experimental group 1, experimental group 2 and experimental group 3, respectively.

[0019] Three groups of unshelled Artemia cysts were taken as control group 1, control group 2 and control group 3, respectively. The three groups of control groups were directly stored under corresponding conditions without being placed in the protective medium.

[0020] The experimental group 2 and the experimental group 3 were respectively placed in the protective medium for preservation. The main components of the protective medium were glucose, lactose, and vitamin C. The concentration of glucose in the protective medium was 21 mg / L, the concentration of lactose was 13 mg / L, and vitamin C The concentration is 30mg / L, the salinity of the protection medium is...

Embodiment 2

[0028] Taking Russian eggs as an example, the hatching percentage of artemia cysts after shelling and preservation are introduced.

[0029] Three groups of shelled Artemia cysts treated with sodium hypochlorite oxidation and dehulling were taken as experimental group 1, experimental group 2 and experimental group 3, respectively.

[0030] Three groups of unshelled Artemia cysts were taken as control group 1, control group 2 and control group 3, respectively. The three groups of control groups were directly stored under corresponding conditions without being placed in the protective medium.

[0031] The experimental group 2 and the experimental group 3 were respectively placed in the protective medium for preservation. The main components of the protective medium were glucose, lactose, and vitamin C. The concentration of glucose in the protective medium was 18mg / L, the concentration of lactose was 12mg / L, and vitamin C The concentration is 25mg / L, and the salinity of the prote...

Embodiment 3

[0039] Taking unprocessed raw raw eggs as an example, the hatching percentage of Artemia cysts after shelling and preservation are introduced.

[0040] Three groups of shelled Artemia cysts treated with sodium hypochlorite oxidation and dehulling were taken as experimental group 1, experimental group 2 and experimental group 3, respectively.

[0041] Three groups of unshelled Artemia cysts were taken as control group 1, control group 2 and control group 3, respectively.

[0042] Another two groups of deshelled Artemia cysts treated by the above dehulling method were taken as control group 4 and control group 5 respectively, and were directly preserved without adding a protective medium.

[0043] The experimental group 2 and the experimental group 3 were respectively placed in the protective medium for preservation. The main components of the protective medium were glucose, lactose, and vitamin C. The concentration of glucose in the protective medium was 20 mg / L, the concentrat...

Abstract

The invention provides a method for increasing the hatching rate of artemia cysts after shelling. The method includes, after shelling, placing the artemia cysts in the protection medium for preservation. The protection medium includes water soluble sugars or water soluble vitamins or a mixture of both. By the aid of the method, the problems that the hatching rate of the artemia cysts after shelling is low and the hatching rate of the shelled artemia cysts after preservation is low are solved, the high hatching rate of the shelled artemia cysts is maintained during preservation, and the commodity attribute of the shelled artemia cysts is enhanced accordingly.

Description

technical field [0001] The invention relates to the technical field of Artemia cyst hatching, in particular to a method for improving the hatching rate of Artemia cysts after shelling. Background technique [0002] Artemia (Brine shrimp, Artemia), commonly known as Artemia, is a class of small crustaceans that live in high-salinity waters. The nauplii of Artemia that hatch for 1-2 days have a large amount of yolk, rich in protein, Fat is a good opening bait for larvae such as fish, shrimp and crab, which can greatly improve the survival rate of artificial breeding of fish and shrimp without polluting water quality. [0003] With the continuous development of the aquaculture industry, Artemia larvae and adults are becoming more and more popular. After Artemia cysts hatch, the newly hatched nauplii of Artemia are mixed with egg shells and unhatched eggs, and the newly hatched nauplii need to be separated from them, which not only requires manpower and material resources, but ...
