Problems solved by technology

Crabs have been generally recognized as a delicacy by Chinese and overseas people. At present, because the source of crabs is still mainly fishing, there is less artificial cultivation work. Naturally grown crabs have far been unable to meet people's food needs. Relying on small-area farming to supplement the needs of the market also cannot alleviate the needs of the market
[0003] At present, there are still many deficiencies in the technology of artificially raising crabs, and people's experience in artificially raising crabs is not yet perfect.
Breeding crabs require different baits at different stages, and require different growth environments. Many technicians ignore the scientific setting of the ecological environment for crab farming when breeding crabs, use industrial compound feed, and use drugs blindly, causing damage to the ecological environment of crabs. Crab survival rate is low, quality declines

Embodiment Construction

[0021] The culture method of crab comprises the following steps:

[0022] (1) Choose a pond; choose a water area with good water quality, no pollution, and a flat bottom, surround it with a fence, and build a pond; the fence should be inserted into the pond at a height of 60 cm, and a reinforcement board should be laid at the bottom of the fence to prevent crabs from escaping;

[0023] (2) Build a crab breeding environment; remove excess silt at the bottom of the pond, it is advisable to leave 12cm deep silt, then thoroughly disinfect, change the water thoroughly after disinfection, and set up multiple air outlets at 5-10cm inside the silt. Hose, the hose is connected to the aerator, and oxygen is added to the pond through the aerator and the hose to avoid suffocation of the crabs; plant aquatic plants in the pond, the aquatic plants are not only the food of the crabs, but also can purify the water quality, the main species of aquatic plants For bitter grass, Elodea and Hydril...

Abstract

The invention belongs to the field of animal cultivation, and particularly relates to an antivirus cultivation method for crabs. The cultivation method for the crabs is high in survival rate of the crabs, growth speed and quality of the crabs. The cultivation method for the crabs comprises the following steps that a water area with good-quality pollution-free water and with a smooth bottom of a pool is chosen, a fence is arranged around the water area, and the pool is constructed; water plants are planted in the pool; juvenile crabs are placed into the pool, and the cultivation density is appropriately 400-500 crabs per mu; in the crab cultivation process, cultivation conditions are frequently observed and regulated; in the crab cultivation process, bait throwing is carried out twice a day in the morning and at evening; merchandise crabs can be caught to appear on the market through crab cages in October.

Description

technical field [0001] The invention belongs to the field of animal breeding, in particular to a method for cultivating crabs. Background technique [0002] Crabs, also known as river crabs, are freshwater crustaceans that grow up in freshwater. The crab meat is delicious and nutritious. Crabs have been generally recognized as a delicacy by Chinese and overseas people. At present, because the source of crabs is still mainly fishing, there is less artificial cultivation work. Naturally grown crabs have far been unable to meet people's food needs. Relying on small-area breeding to supplement the needs of the market will not alleviate the needs of the market either. [0003] At present, the technology of artificially cultivating crabs still has many deficiencies, and people's experience in artificially cultivating crabs is still not perfect. Breeding crabs require different baits at different stages, and require different growth environments. Many technicians ignore the scien...
