Problems solved by technology

[0006] At present, with people's love for crabs and suitable management methods, the aquatic product industry of crabs has developed rapidly, and the breeding methods of crabs are also relatively complicated, which has caused many problems, such as unknown crab species and the introduction of foreign diseases; environmental deterioration cannot satisfy crabs. Substances needed for normal growth; free use of antibiotics, hormones and other drugs, use of industrial feed, damage the body circulation of crabs, reduce the output and quality of crabs
These unscientific breeding methods have seriously damaged the ecological environment of crabs, resulting in damage to the quality of crabs and the economic benefits they produce, which is not conducive to the circular development of the crab aquatic product industry. Therefore, a pollution-free, scientific and sustainable development method is required. Crab farming technology

Embodiment 1

[0025] Choose a pond with sufficient water source, no pollution, flat bottom, and no water leakage. The pond is rectangular, with an aspect ratio of 3:4, a depth of 1.1m, and a circular groove at the bottom with a depth of 0.3m. The area of ​​the circular groove is Accounting for 60% of the pond area, the pond is lined with an impermeable membrane around the pond, and four water inlets and outlets are set, and a 60-mesh filter mesh is put on the water inlets and outlets, exposed to the sun for 5 days, and a standby pond is obtained.

[0026] Add water to the pond to be used, adjust the water depth to 0.15m, sterilize the water in the pond, plant bitter grass and aquatic plants, and put loach and diatoms, wherein the covered area of ​​aquatic plants accounts for 40% of the pond area, and the amount of loach released It is 18 tails / mu, and the application rate of diatoms is 10kg / acre, then add water to the water depth of 0.7m, spread EM bacteria biological preparations and fermen...

Embodiment 2

[0030] Choose a pond with sufficient water source, no pollution, flat bottom, and no water leakage. The pond is rectangular, with an aspect ratio of 3:4, a depth of 1.4m, and a circular groove at the bottom with a depth of 0.4m. The area of ​​the circular groove is It accounts for 80% of the area of ​​the pond. The surroundings of the pond are lined with impermeable membranes, and 6 water inlets and outlets are set, and an 80-mesh filter mesh is put on the water inlets and outlets, exposed to the sun for 5 days, and a standby pond is obtained.

[0031] Add water to the pond to be used, adjust the water depth to 0.3m, sterilize the water in the pond, plant Elodea aquatic plants, and put loach and diatoms, wherein the covered area of ​​aquatic plants accounts for 60% of the pond area, and the release of loach The amount is 25 tails / mu, the amount of diatoms is 30kg / mu, and then water is added to the water depth of 0.8m, and the Bacillus biological agent and fermented chicken manu...

Embodiment 3

[0035] Choose a pond with sufficient water source, no pollution, flat bottom, and no water leakage. The pond is rectangular, with an aspect ratio of 3:4, a depth of 1.3m, and a circular groove at the bottom with a depth of 0.35m. The area of ​​the circular groove is Accounting for 70% of the pond area, the pond is lined with an impermeable membrane around the pond, and five water inlets and outlets are set, and a 70-mesh filter mesh is put on the water inlets and outlets, exposed to the sun for 5 days, and a standby pond is obtained.

[0036] Add water to the pond to be used, adjust the water depth to 0.2m, plant water peanuts and aquatic plants after sterilizing the water in the pond, and put loach and diatoms, wherein the coverage area of ​​aquatic plants accounts for 50% of the pond area, and the amount of loach released It is 20 tails / mu, and the application rate of diatoms is 20kg / acre, then add water to the water depth of 0.75m, spread the chicken manure of bacillus biolo...

Abstract

The invention discloses an ecological breeding method of Eriocheir sinensis. The method comprises the steps that a pond is prepared firstly, an annular groove, an anti-permeable membrane and an inlet and outlet water pipe with a filtering mesh are arranged, water is poured after exposure, water plants are planted and loaches and diatom are placed in the pond after disinfection,, a biological agent and chicken manure are scattered and fertilized after water adding, the temperature, the dissolved oxygen and the PH value of the water are adjusted, the breeding pond is obtained, young Eriocheir sinensis is thrown into the breeding pond after being sterilized, feeding is carried out according to different growth periods of the Eriocheir sinensis, plant ash, the biological agent and inorganic salt type nutrient substances are scattered and fertilized regularly, and periodic water cleaning and disinfecting are carried out. According to the ecological breeding method, the environment and nutrient substances needed in the growth period of the Eriocheir sinensis can be provided, fast growth of the Eriocheir sinensis can be promoted, the specification and yield of the Eriocheir sinensis can be improved, and the method is ecological, environmentally friendly and economical.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of aquaculture, and in particular relates to an ecological breeding method for Chinese mitten crabs. [0003] Background technique: [0004] Chinese mitten crab is also commonly known as river crab, hairy crab, clear water crab and hairy crab. It is an omnivorous animal and likes to eat fish, shrimp, snails, mussels, worms, earthworms, insects and their larvae. Eriocheir sinensis has a delicious taste and is deeply loved by people. Moreover, the crab contains more vitamin A, and proper use is also beneficial to people's health. [0005] Crabs grow in fresh water and reproduce in sea water, and like to live in burrows in river bends and lakes with rich bait, so artificial breeding crabs need to choose places with sufficient water sources, convenient drainage and water intake, and good water quality. Increase the number of habitats, increase the output of crabs, and use plastic films or cement boards a...
