Device and use method for wild Monopterus albus domestication

A method for wild Monopterus albus domestication, wherein the method adopts a device for wild Monopterus albus domestication, and the device comprises:

• a circular water tank, wherein the circular water tank is placed on a bracket, a groove is arranged in the circular water tank, a drainpipe is arranged in the groove, a plug is detachably connected to the drainpipe, the plug extends out of the circular water tank, the plug passes through the bracket, a water inlet pipe is fixedly connected to the circular water tank, a valve is installed on the water inlet pipe, a water grass fixing frame is placed in the circular water tank, a material table is arranged in the circular water tank, a water quality monitoring instrument is placed in the circular water tank, a plurality of bubble stones and a heating rod are placed in the circular water tank, a hose is communicated with the bubble stones, an aerator is communicated with one end of the hose far away from the bubble stones, and an imitating ecological Monopterus albus nest and a plurality of volcanic rocks are placed in the circular water tank;
• and
• the imitating ecological Monopterus albus nest is a PVC material wave-shaped horizontal stripe square piece;
• the method comprises following steps:
• S1, device preparation:
• firstly, all parts of the domestication device are assembled, the domestication device is disinfected by potassium permanganate solution, then a Pistia stratiotes L. is transplanted into the water grass fixing frame, and the Pistia stratiotes L. covers half of the water surface;
• S2, stocking method:
• introducing running water into the circular water tank, and keeping a water level at 0.7-0.9 m and pH at 7.0-7.5;
• adding anti-stress nutrients;
• according to 50-100 eels/m2 water body, Monopterus albus offspring seeds with specifications of 8-15 g/eels should be stocked, and the Monopterus albus offspring seeds should be disease-free, injury-free, with complete mucus and neat specifications, and come from a local area;
• the Monopterus albus offspring seeds should be caught in professional Monopterus albus cages within 48 hours and tested for epidemic diseases, without long-term storage, transportation, electric shock, or drug anesthesia;
• when the offspring seeds are released, the Monopterus albus offspring seeds are placed in a special frame beside the circular water tank and let stand for 5 minutes, then the offspring seeds are soaked in the circular water tank for 3 times, lasting for 15 seconds, 20 seconds and 60 seconds respectively, and finally the offspring seeds are poured into water;
• S3, disposal method:
• after pouring the Monopterus albus offspring seeds into the water in the circular water tank for 3 days, observing the death of the Monopterus albus offspring seeds, picking out the dead offspring seeds, turning on the heating rod, raising the temperature slowly, and the temperature is stopped for 1 hour every 2° C. rise until the temperature is raised to 32° C. for 7 days;
• on the fourth day after the offspring seeds are released, earthworm is fed according to 1.5-3% of the weight of the Monopterus albus offspring seeds, once a day and at night every time, and the earthworm is placed on the material table when feeding;
• feeding fresh earthworm on the fourth to sixth day after offspring seeds are released, and feeding chopped fresh earthworm on the seventh to tenth day;
• insect repellent and bactericidal drugs are put on the twelfth day after offspring seeds are released for three days;
• S4, feed-switching domestication:
• feed-switching domestication is started on the thirteenth day after the offspring seeds are released, and chopped mixed commercial feed of earthworm is used to form a domestication material for domestication, and the domestication lasts for 10 days;
• and
• S5, micro-ecological construction:
• after domestication, 1.5 kg of clean and fresh snails and 1.5 kg of shellfish are put into the circular water tank, and 0.2 g/L of Bacillus is used regularly;
• the circular water tank is made of glass fiber reinforced plastic or food-grade PVC, with a diameter of 2 m and a depth of 1 m, a smooth inner wall and a black color;
• wherein the mass fraction of the potassium permanganate solution in the S1 is 15-25%, and the volume of the circular water tank is 3.14 m3;
• in the S1, 5-8 stems and leaves of the Pistia stratiotes L. are tender green, the root system is intact, there is no insect, and there is no withering and yellow;
• the formula of the anti-stress nutrients in the S2 is:
• 3-5 g of sucrose, 1-5 g of vitamin C, 2-3 g of houttuynia cordata and 3-5 g of licorice per liter of water;
• a detection of epidemic diseases in the S2 comprises the detection of pathogenic microorganisms, and the detection method adopts randomly selecting the microorganisms on the surface of the Monopterus albus offspring seeds, the environment and transportation equipment, and carrying out microbial culture and sequencing judgment;
• dosage of the insect repellent and bactericidal drugs in the S3 is 0.05-1 g of neem leaves and 0.01-0.02 g of dried pomegranate peel per liter of water;
• and
• a preparation method of the domestication material described in the S4 comprises the following steps:
• mixing and pulverizing the chopped earthworm into powder commercial material, adding water, stirring into dough coagulated but not dispersed, and adding taurine according to 0.2-0.8% of the weight of the domestication material;
• and the weight ratio of the earthworm to the commercial material is 4:1, 2:1, 1:1, 1:2, 1:4 and 0:5 in sequence, and is adjusted every two days.
