Problems solved by technology

[0004] As crabs become more and more popular with people, more and more people choose to breed crabs. In the process of raising crabs, people need to promote the growth of crabs by feeding feed, which also plays a role in improving the meat quality of crabs. However, existing The feed ingredients are single, which cannot achieve this effect, and because the nutrients in the crab feed are unreasonable, there are defects that the growth of crabs is slow and the survival rate of breeding is not high
[0005] Moreover, many crabs are now cultured directly with hormones, which have low nutritional value

Embodiment 1

[0020] The invention discloses a special cultivation method for crabs. The cultivation of crabs is completed through the steps of selecting ponds, cultivating aquatic organisms, selecting juvenile crabs, feeding and water quality control. The specific steps are as follows:

[0021] (1) Selection of ponds: select a pond with an area of ​​1 mu and a depth of 1m, spread a 2:1 ratio of sandy loam and gravel soil with a thickness of 2cm at the bottom of the pond, drain the pond water, and expose the bottom of the pond for 10 days. Build anti-escape facilities around the pool. The water inlet and outlet of the pool are surrounded by barbed wire with a diameter of less than 1cm to prevent crabs from escaping. After filling the pool with water at a height of 30cm, sprinkle quicklime at a rate of 100g per square meter into the pool. for disinfection;

[0022] (2) Cultivation of aquatic organisms: Cultivate aquatic plants that take up two-thirds of the volume of the pool to provide feed...

Embodiment 2

[0028] The invention discloses a special cultivation method for crabs. The cultivation of crabs is completed through the steps of selecting ponds, cultivating aquatic organisms, selecting juvenile crabs, feeding and water quality control. The specific steps are as follows:

[0029] (1) The selection of pond: select the pond that area is 5 acres, depth is 1.4m, spread the sandy loam soil and gravel soil that are 2:1 ratio of 4cm in thickness at the bottom of the pond, drain the pond water, expose to the sun for 14 days at the bottom of the pond, Build anti-escape facilities around the pool. The water inlet and outlet of the pool are surrounded by barbed wire with a diameter of less than 1cm to prevent crabs from escaping. After pouring water into the pool at a height of 30cm, sprinkle 100g per square meter of water into the pool. quicklime for disinfection;

Abstract

The invention discloses a breeding method special for crabs. The crabs are bred through the steps of pond selection, aquatic organism cultivation, juvenile crab selection, feeding and water quality control; by adding compound amino acid, the appetite and absorption function of the crabs are stimulated, the physique of the crabs is improved, and therefore the survival rate of the crabs is ensured;the nutrients are rich, sufficient nutrients are provided for the crabs, the function of improving the meat quality is achieved, the development speed of the crabs is increased, and the growth cycle of the crabs is shortened; meanwhile, the method adopts a granulation mode, feeding is convenient, the nutritional value of the bred crabs can be effectively ensured, fish diseases are effectively prevented, and the method has the advantage that the survival rate of the crabs is high.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a special breeding method for crabs. Background technique [0002] Crabs are crustaceans whose bodies are protected by hard shells and breathe through gills. In taxonomy, it is the same animal as shrimp, lobster, and hermit crab. The vast majority of crabs live in the sea or near the sea, and some live in fresh water or land, and crabs are rich in protein and delicious, so they are very popular. [0003] They rely on the female crab to give birth to small crabs, and each time the female crab will lay a lot of eggs, the number can reach more than millions. Crabs rely on the geomagnetic field to determine direction. China has a long history of eating crabs, which are recorded in "Yi Zhou Shu Wang Hui Jie" and "Zhou Li Tian Guan Bu Ren". [0004] As crabs become more and more popular with people, more and more people choose to breed crabs. In the process of raising crabs, people need ...
