In recent years, Jiefang eyebrow crab has been served on the table as a seafood specialty. Because of its thin shell and delicious yolk, the yolk in the body is rich in nutrients in autumn and winter, so the demand has increased year by year, which has led to an increase in its excavation; The discharge of pollutants has destroyed its living environment and seriously affected the reproductive survival rate of the liberated eyebrow crab; so the survival number of the wild population of the liberated eyebrow crab has been in a downward trend

Embodiment Construction
[0025] Further description will be given below in conjunction with specific examples. This embodiment is carried out throughout the year along the coast of Rizhao, Shandong.
[0026] A fish farming workshop with a glass-steel tile roof is used. There are 36 cement pools of 30㎡ in the shed, with a depth of 0.5m. Equipped with an Artemia egg hatching device, that is, a conical incubator, a 2000W electric heating rod, a temperature controller, a micro-oxygenation pump, and a stirring rod. The light intensity of the breeding workshop is 6000lx, and there is no temperature control facility.
[0027] Before releasing the seedlings, sterilize the entire workshop, including the breeding pond, walkways, and all tools with bleach for 24 hours, and then rinse them with clean fresh water or sea water.
[0028] Take medium-fine sea sand with a particle size of 0.2mm-0.5mm, sieve to remove impurities such as gravel, shells, and soil, and then wash it with a concentration of 20×10 -6 Disi...

Abstract
The invention discloses an artificial culturing method for blepharipoda liberata, and relates to the technical field of aquaculture, in particular to an indoor factorial artificial culturing method for blepharipoda liberata. The method is characterized by comprising the steps of preparing culturing facilities, placing seedlings into a pond, throwing baits for feeding, regulating and controlling water quality, preventing and treating diseases, performing overwintering management and others. The survival rate of culturing can be increased, the increasing market demand for the blepharipoda liberata is met, the situation that natural resources are excessively dredged is reduced, the sufficient and stable parent source needed for large-scale artificial breeding is provided, and compared with growth of the blepharipoda liberata in the natural environment, the method has the advantages of being high in survival rate, large in yield of cultured blepharipoda liberata per unit area, good in quality and free of limits of natural conditions.
Description
technical field [0001] The invention relates to the technical field of aquaculture, in particular to an indoor industrial artificial culture method for liberating eyebrow crabs. Background technique [0002] Liberated eyebrow crab is not a real crab, it is a heterotailed creature that lives on the ocean tidal flats between shrimps and crabs. Because its shape is similar to the "Cicada" on the tree, it is also called "Hai Zhile". It is distributed in the Shandong sea area, and the wild resources are very limited. In recent years, Jiefang eyebrow crab has been served on the table as a seafood specialty. Because of its thin shell and delicious yolk, the yolk in the body is rich in nutrients in autumn and winter, so the demand has increased year by year, which has led to an increase in its excavation; The discharge of pollutants has destroyed its living environment and seriously affected the reproductive survival rate of the liberated eyebrow crab; so the survival number of th...
