Problems solved by technology

Now the scope of crab breeding is constantly expanding, but the breeding density of crabs is relatively low, usually about 800 / mu, and the economic benefits are not high. In addition, because artificial feed is mainly used in the breeding process, the crabs do not move much during the growth process. Poor quality crab meat

Embodiment Construction

[0008] A method for cultivating crabs, comprising the following steps: (1), select a pond, select a pond of 2-4 acres, in the pond, there are deep water areas and shallow water areas, and the deep water areas and shallow water areas are in alternating bands, each The width of the deep water area is 1-1.5m, and the width of each shallow water area is 0.5-0.8m. The depth difference between the deep water area and the shallow water area is 10-20cm. Finally, expose the bottom of the pond to the sun for 2-3 days to sterilize, and then inject water into the pond. The water depth is controlled at 30-50cm, and the oxygenation rod is used to increase oxygen in the water, so that the dissolved oxygen in the pond water is above 8mg / L , plant aquatic plants in the pond, aquatic plants are water peanuts, duckweed, etc., and stock fry with a length of 2-5cm, and the amount of feeding per mu is 2000-3000 to provide food for crabs. When aquatic plants cover 70% of the pond area, Stocking crab...

Abstract

The invention belongs to the field of breeding, and particularly relates to a crab breeding method. In the crab breeding process, fish fries are placed to serve as bait of crabs so that stocking density of the crabs can be large, and meanwhile the fish fries can serve as bait in the crab growing process. Fishes captured by the crabs in a pond are increased while artificial feed is provided for the crabs, moving time of the crabs is prolonged, the health conditions of the crabs are improved, the survival rate in the breeding process is increased, and meat quality of the crabs is also improved.

Description

technical field [0001] The invention belongs to the field of cultivation, and in particular relates to a method for cultivating crabs. Background technique [0002] Crabs are rich in protein and trace elements, which have a good nourishing effect on the body. Crab contains more vitamin A, which is helpful for skin keratinization. Crabs also have anti-tuberculosis effects, and eating crabs is of great benefit to the recovery of tuberculosis. Now the scope of crab breeding is constantly expanding, but the breeding density of crabs is relatively low, usually about 800 / mu, and the economic benefits are not high. In addition, because artificial feed is mainly used in the breeding process, the crabs do not move much during the growth process. The meat quality that causes crab is poor. Contents of the invention [0003] The object of the invention is to provide a method for cultivating crabs, which improves the density and survival rate of crabs and improves the meat quality o...
