Problems solved by technology

Crab is currently a delicacy generally recognized 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 can no longer 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
Similarly, the current technology for crab breeding is still relatively chaotic, and most of them are small workshops, with low efficiency, unstable quality, and high crab mortality.

Embodiment 1

[0017] A breeding method for high-quality crabs, comprising the following steps:

[0018] (1) Pond selection: The pond area is 1.5 mu, the water depth is 1.6 meters, and the soil depth at the bottom of the pond is 0.3 meters. The pond requires a quiet environment, sufficient sunlight, abundant water sources, fresh water quality, and convenient drainage and irrigation. It is equipped with deep water areas and shallow water areas;

[0019] (2) Supporting water system: water inlets and outlets are set at both ends of the pond. A tube bag made of sieve silk;

[0020] (3) Construction of the anti-escape wall: Use cement boards as hoardings, supported by bamboo and wood piles, and tie the seams with fine iron wires, leaving 0.5 meters above the soil and 0.2 meters below the soil, and the four corners are built into arcs;

[0021] (4) Pond cleaning: Disinfect the pond with bleaching powder before the crabs are stocked. The bleaching powder is mixed with 5g / ton of water, and 150kg of...

[0029] A breeding method for high-quality crabs, comprising the following steps:

[0030] (1) Pond selection: The pond area is 1.8 mu, the water depth is 1.9 meters, and the soil depth at the bottom of the pond is 0.4 meters. The pond requires a quiet environment, sufficient sunlight, abundant water sources, fresh water quality, and convenient irrigation and drainage. It is equipped with deep water areas and shallow water areas;

[0031] (2) Supporting water system: water inlets and outlets are set at both ends of the pond. A tube bag made of sieve silk;

[0032] (3) Construction of the anti-escape wall: Asbestos tiles are used as hoardings, supported by bamboo and wood piles, and thin iron wires are used to tie the seams, leaving 0.6 meters above the soil and 0.3 meters below the soil, and the four corners are built into arcs;

[0033] (4) Pond cleaning: Disinfect the pond with bleaching powder before the crabs are stocked. The bleaching powder is mixed with 5g / ton of water,...

Embodiment 3

[0041] A breeding method for high-quality crabs, comprising the following steps:

[0042] (1) Pond selection: The pond area is 2.1 mu, the water depth is 2.2 meters, and the soil at the bottom of the pond is 0.5 meters deep. The pond requires a quiet environment, sufficient sunlight, abundant water sources, fresh water quality, and convenient irrigation and drainage. It is equipped with deep water areas and shallow water areas;

[0043] (2) Supporting water system: water inlets and outlets are set at both ends of the pond. A tube bag made of sieve silk;

[0044] (3) The construction of the anti-escape wall: use ore tiles as hoardings, supported by bamboo and wood piles, and thin iron wires to tie the seams, leaving 0.7 meters above the soil and 0.4 meters below the soil, and the four corners are built into arcs;

[0045] (4) Pond cleaning: Disinfect the pond with bleaching powder before the crabs are stocked. The bleaching powder is mixed with 5g / ton of water, and 150kg of or...

The method comprises the following steps: pond selection, drainage facilities, blocking wall construction, pond cleaning, crab fry treatment and stocking, bait preparation and feeding, daily temperature and illumination management, etc. The breeding method for the high-quality crab disclosed by the invention can improve crab breeding environment, increase the yield of the crab, reduce the mortality of the crab, and improve the quality of the crab.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating high-quality 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 are rich in protein and trace elements, which have a good nourishing effect on the body. Under the premise that people's living standards have been significantly improved, the demand for aquatic products in the diet continues to increase, coupled with the continuous advancement of modern aquatic product breeding technology, a large number of artificially farmed seafood products are gradually increasing, and there are also improvements in farming technology. Innovation and perfection. Crab is currently a delicacy generally recognized by Chinese and overseas people. At present, because the source of crabs is still mainly fishing, there is less artificial cultivation work. Natu...
