Embodiment 1

[0015] The culture method of present embodiment river prawn, comprises the following steps:

[0016] (1) The construction of the breeding pond: the breeding pond is a pond with an area of ​​2 mu and a water depth of 1.5 meters. Filters are installed at the inlet and outlet of the pond. The bottom of the pond is sandy or hard mud, and the silt does not exceed 20 cm. A cross-shaped shrimp collection ditch is dug at the bottom of the pond, 70 cm wide and 30 cm deep, so that the shrimp can be collected in the ditch when the river shrimp is harvested in autumn, and it is easy to pick up;

[0017] (2) Cleaning of the breeding pond: apply 100 kilograms of quicklime per mu, dig a pit by the pond, place the quicklime in the pit, wait for it to melt, sprinkle the whole pond evenly, stir the bottom of the pond the next morning to prevent the ash from depositing on the bottom, thoroughly Irrigate the pond 3 days after clearing the pond, and the irrigation water should be strictly filtered...

Embodiment 2

[0022] The culture method of present embodiment river prawn, comprises the following steps:

[0023] (1) The construction of the breeding pond: the breeding pond is a pond with an area of ​​4 mu and a water depth of 1.5 meters. Filters are installed at the inlet and outlet of the pond. The bottom of the pond is sandy or hard mud, and the silt does not exceed 20 cm. A cross-shaped shrimp collection ditch is dug at the bottom of the pond, 75 cm wide and 35 cm deep, so that the shrimp can be collected in the ditch when the river shrimp is harvested in autumn, and it is easy to pick up;

[0024] (2) Cleaning of the breeding pond: Apply 120 kg of quicklime per mu, dig a pit by the pond, place the quicklime in the pit, wait for it to melt, and sprinkle the whole pond evenly, stir the bottom of the pond the next morning to prevent the ash from depositing on the bottom, thoroughly Irrigate the pond 4 days after clearing the pond, and the irrigation water should be strictly filtered to...

Embodiment 3

[0029] The culture method of present embodiment river prawn, comprises the following steps:

[0030] (1) The construction of the breeding pond: the breeding pond is selected from a pond with an area of ​​5 mu and a water depth of 2 meters. Filters are installed at the inlet and outlet of the pond. The bottom of the pond is sandy or hard mud, and the silt does not exceed 20 cm. Dig a cross-shaped shrimp collection ditch at the bottom of the pond, 80 cm wide and 40 cm deep, so that the shrimp can be collected in the ditch when the river shrimp is harvested in autumn, and it is easy to pick up;

[0031] (2) Cleaning of the breeding pond: Apply 150 kg of quicklime per mu, dig a pit by the pond, place the quicklime in the pit, wait for it to melt, and sprinkle the whole pond evenly, stir the bottom of the pond the next morning to prevent the ash from depositing on the bottom, thoroughly Irrigate the pond 5 days after clearing the pond, and the irrigation water should be strictly fi...

Abstract

The invention relates to a shrimp cultivation method and belongs to the technical field of cultivation methods. The shrimp cultivation method comprises the following steps: (1) building a cultivation pool; (2) cleaning the cultivation pool; (3) preparing before young shrimp placement; (3) placing young shrimps; and (5) feeding bait. The shrimp cultivation method can form a stable ecosystem, ensures reasonable bait matching, can enhance the autoimmunity of shrimps, improves the survival rate of shrimps and shortens the growth time of shrimps, thereby enabling in-time marketing of shrimps to achieve balance between supply and demand; meanwhile, as the bait is combined by natural vegetation and Chinese herbal medicines, the bait cost is reduced for fishermen, the shrimp is fresh and tender in texture and is pollution-free, and accordingly, no safety threat can be brought to human bodies. The cultivation method ensures stable yield and rich harvest, and not only increases the income of fishermen but also provides rich nutrient substances for consumers.

Description

[0001] technical field [0002] The invention relates to a cultivation method of river prawns, belonging to the technical field of cultivation methods. Background technique [0003] With the improvement of people's living standards, and because river prawns are tender, delicious and nutritious, they are high-protein and low-fat aquatic foods, which are quite popular among consumers. Therefore, the demand for river prawns is also increasing. Therefore, vigorously It is imperative to develop river shrimp farming. There are many favorable conditions for river prawn farming: the seedlings of river prawns are easy to solve, there is no need to add a lot of equipment, a large number of seedlings can be obtained in the pond, and the growth of river prawns does not have high requirements for bait. However, the farming technology of river prawns is not mature enough, resulting in low yield and high price. Contents of the invention [0004] The purpose of the present invention i...
