Embodiment Construction

[0037] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0038] A method for crab ecological cultivation is characterized in that it comprises the following steps:

[0039]S1. Build a culture pond: The culture pond is set as a slope structure, and the bottom slope extends to the water surface on one side of the culture pond, and a fence is built to form a pond; it is advisable to insert the fence at the bottom of the pond by 60 cm, and lay reinforcement plates at the bottom of the fence to prevent crabs flight;

[0040] S2. Treatment of breeding ponds: remove excessive silt at the bottom of the breeding pond, it is advisable to leave 12cm deep silt, then thoroughly disinfect, change the water thoroughly after disinfection, and install a soft water tank with multiple air outlets ...

Abstract

The invention provides an ecological crab breeding method, and belongs to the technical field of ecological breeding. The ecological crab breeding method is characterized by comprising the following steps: S1, construction of a culture pond: arranging the culture pond into a slope type structure, enabling the slope at the bottom to extend to the water surface on one side of the culture pond, and enclosing with fences to build a pond; inserting the fences into the bottom of the pond by a distance of 60 cm, and laying reinforcing plates at the bottoms of the fences to prevent crabs from escaping; S2, treatment of the culture pond: removing excessive sludge at the bottom of the culture pond, reserving sludge with the depth of 12 cm, then thoroughly sterilizing, thoroughly changing primary water after sterilizing, arranging a hose with a plurality of air outlets at the position of 5-10 cm in the sludge, connecting the hose with an aerator, and filling oxygen into the pond through the aerator and the hose so as to avoid crab suffocation. Water grass is planted in the pond, and the water grass is not only the food of crabs, but also can improve the water quality.

Description

technical field [0001] The invention belongs to the technical field of ecological cultivation, in particular to a method for ecological cultivation of 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. Farming crabs require different bait at different stages, and require different growth environments. Many...
