Method for breeding crays

[0020] Example 1:

[0021] see figure 1 , a crayfish culture method, the culture 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 1.2-2.5m deep. The pond is divided into shallow water area and deep water area, and the depth of the shallow water area is 0.9~ The depth of the deep water area is 1.2m, the depth of the deep water area is 1.7~2.2m, and the ratio of the shallow water area and the deep water area to the overall area of ​​the pond is 3:1, and then a mud stalk is built in the middle of the pond for the crayfish to burrow, and slopes are built around the pond. To prevent crayfish from burrowing to escape, and set up isolation nets around the slope of the pond, the height of the isolation nets is 0.6-0.7m, and the isolation nets are inserted into the pond ground 40-47cm, and there are 3 water inlets and 1 water outlet in the pond. , each water inlet is provided with three layers of filter screens, and the first layer of filter screen is a 20 mesh metal mesh cover, the second layer of filter screen is a sponge filter layer, the third layer of filter screen is an activated carbon filter layer, and the third layer of filter screen is The net is close to the pond, and a layer of filter net is installed at each outlet, and the filter net is a 20-mesh metal mesh cover. The water in the pond is drained, the natural enemies of lobsters are removed, and the pond is exposed to the sun for 3 to 5 days to obtain an empty pond;

[0023] B. Pond disinfection treatment: apply 150-200kg of decomposed human urine or poultry manure per mu, then use quicklime with a concentration of 80-100kg/mu to disinfect the whole pond, and lay 2 layers of rotten sandy soil at the bottom of the pond , each layer is exposed to the sun and sterilized and then superimposed on the next layer. The thickness of each layer of humus sand is 0.3-0.6cm, and the number of days of exposure of each layer of humus sand is 1 day. Clams, mussels, earthworms, water earthworms, and the aquatic plants are one or more of the water lily, water hyacinth, marigold, green grass, bitter grass, water peanut, black algae, water hyacinth, and covered by water plants The area is 45-55% of the entire pond area. The total amount of eels, snails, mussels, earthworms and water worms put in is controlled at 3-4% of the total weight of the shrimp group, and decomposed microbial organic fertilizer is thrown into the pond. Here During the process, a shelter needs to be set up, and the shelter is a sunscreen net, which is connected to a support rod, and the support rod is inserted into the pond ground for 40-50cm. At the same time, the sunscreen net is made of high-density polyethylene, and its aperture is 3 needles;

[0024] C. Feeding: Select shrimp species with a length of 0.8-1cm with strong disease resistance and adaptability, soak them in salt water with a concentration of 3% per cubic meter for 20-30 minutes, and then put them into the pond. 40 ~ 70kg, the ratio of male to female shrimp species is 8:3, and lobster feed is fed within 30 to 50 minutes after placement. From the first week to the seventh week, lobster feed is fed twice a day, and the amount of feeding is the body weight of the lobster. After the eighth week, the lobster feed was fed 3 times a day, and the feeding amount was 10-11% of the body weight of the shrimp. At the same time, the lobster feed consisted of pig blood, earthworm meal, selenium-enriched wheat flour, fermented soybean meal, and peanut cake. It consists of 30-70 parts of pig blood, 20-40 parts of earthworm powder, and 40-60 parts of selenium-enriched wheat flour. ; 100-150 servings of fermented soybean meal; 10-30 servings of peanut cake; 15-30 servings of snail meat puree; 10-25 servings of mussel puree; 80-150 servings of fish meal; 3-8 servings of vitamin E; 6 servings;

[0025] D. Water quality monitoring: place the temperature sensor, pH sensor, dissolved oxygen sensor, VOC sensor and consistency sensor in the pond. The number of temperature sensors, pH sensors, dissolved oxygen sensors and consistency sensors are all two, and one is placed in the pond. In the deep water area, one is placed in the shallow water area, the number of VOC sensors is two, one is placed at the inlet of the pond, and the other is placed at the outlet of the pond. At the same time, the temperature sensor, PH sensor, dissolved oxygen sensor, VOC sensor and concentration The consistency sensors are connected to the 4G communication module through wires. The 4G communication module includes a 4G gateway and a remote mobile terminal, and the remote mobile terminal is a smartphone connected to the 4G network. At the same time, the temperature sensor, PH sensor, dissolved oxygen sensor, VOC sensor and concentration The consistency sensor is also connected with the power supply mechanism through the wire, and the power supply mechanism is the mains connected through the wire;

[0026] E. Increase the number of shelling: use electrical stimulation to make the crayfish shell to increase the growth rate, and electrical stimulation is to stimulate the crayfish with an electric current, so that the crayfish can take off the shell during the current vibration process to increase the growth rate;

[0027] F. Fishing: 70 to 100 days after shrimp breeding can be fished with shrimp cages or ground cages, and the aperture of the shrimp cages or ground cages is 5 to 8 cm. Through this method, real-time monitoring of water quality and timely Fishing and strict control of prohibited drugs and inputs make the cultured crayfish pollution-free, and ultimately maximize the economic benefits of crayfish, which not only meets the national demand for energy conservation and emission reduction, but also maximizes the growth rate of crayfish.
