[0002] Crayfish is fresh and tender, delicious and nutritious. It is a high-protein and low-fat aquatic food, so it is widely liked by people. At the same time, with the improvement of living standards, people's pursuit of delicious food is becoming more and more intense. The demand for lobsters is increasing, so the artificial culture of crayfish has become an imperative trend, but the taste of the lobsters produced by the existing lobster farming methods is not very good, and at the same time it cannot improve the quality of the lobsters. The growth rate is not conducive to the interests of the farmers themselves. Therefore, we propose a crayfish farming method

Embodiment 1

[0021] see figure 1 , a crayfish cultivation method, its cultivation method comprises the following steps:

[0022] A. Pond selection and construction: Choose a pond with sufficient water source and no silt, or manually dig a pond with an excavator, and make the pond deep 1.2-2.5m. The pond is divided into shallow water area and deep water area. The depth of the shallow water area is 0.9- 1.2m, the depth of the deep water area is 1.7 ~ 2.2m, and the ratio of the shallow water area to the deep water area of ​​the overall pond area is 3:1. Then build mud stems in the middle of the pond for crayfish to dig holes, and build slopes around the pond To prevent the crayfish from burrowing and escaping, and set up isolation nets around the slope of the pond. The isolation nets are 0.6-0.7m high, and the isolation nets are inserted into the pond ground by 40-47cm. There are 3 water inlets and 1 water outlet in the pond. , each water inlet is equipped with three layers of filter screen,...

Embodiment 2

[0029] A kind of crayfish culture method, its culture method comprises the following steps:

[0030]A. Pond selection and construction: Choose a pond with sufficient water source and no silt, or manually dig a pond with an excavator, and make the pond deep 1.2-2.5m. The pond is divided into shallow water area and deep water area. 1.2m, the depth of the deep water area is 1.8 ~ 2m, and the ratio of the shallow water area and the deep water area to the overall area of ​​the pond is 3:1, then build mud stems in the middle of the pond for crayfish to dig holes, and build ramps around the pond Prevent crayfish from burrowing and escaping, and set up isolation nets around the slope of the pond. The isolation nets are 0.6-0.65m high, and the isolation nets are inserted into the pond ground by 40-45cm. There are 4 water inlets and 3 water outlets in the pond. Each water inlet is equipped with four layers of filters, and the first layer of filters is a 20-mesh metal mesh cover, the sec...

Abstract

The invention discloses a method for breeding crays. The breeding method comprises the following steps that A, a pond is selected and constructed, wherein the pond with sufficient water and no sludgeis selected, or an excavator is utilized for digging the pond manually to make the depth of the pond be 1.2-2.5 m, and then a mud ridge is constructed in the middle of the pond for the crays to burrow; a ramp is constructed on the periphery of the pond to prevent the crays from escaping through burrowing, an isolation screen is arranged on the periphery of the ramp, and three-four water inlets areformed in the pond; 1-3 water outlets are formed in the pond, three or four filtering screen layers are arranged at the water inlets, and one or two filtering screen layers are arranged at the wateroutlets. By adopting the method, water quality can be monitored in real time, the crays can be caught suitably, forbidden drug and put objects are strictly controlled to make the bred crays contamination-free, and finally the economic benefit of the crays is maximum; not only are the requirements for national energy conservation and emission reduction met, but also the growing speed of the crays is increased to a largest extent.
