[0029] The following will be combined with the embodiments of the present invention Figure 1-Figure 3 , the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0030] A method for acclimating larvae of the thrush, comprising the following steps:

[0031] Step 1: Prepare bait. Use povidone iodine 1-2 mg / L or ozone short-time aeration disinfection. Mix the cultivated Artemia with water at a ratio of 1:300 and pour it into the bait tank 1 for initial feeding. The fry density is ≤ 50,000 / m 3 .

[0032] Step 2: Install the pipeline, add an aeration device 2 to the bait tank 1, and let air into the bait tank so that the Artemia bait can be evenly dispersed in the water body to ensure the effect of siphon feeding.

[0033] Step 3: Place one end of the burette 4 into the bait tank and the other end into the seedling cultivation tank 6, open the flow valve 5 for adjustment, so that the Artemia can be siphoned from the bait tank 1 into the seedling cultivation tank 6 by the burette 4.

[0034] Step 4: Before releasing the newly hatched fry, disinfect the seedling cultivation tank with quicklime6.

[0035] Step 5: Transfer 30,000 fry to a seedling cultivation tank 6 with a diameter of 3 meters, open the water inlet and outlet system, control the water flow rate at 4m / min, and after 2 days, observe that there is no abnormality in the activity and start feeding.

[0036] Step 6: Open the flow valve 5 at a fixed time every day, control the titration rate at 100 drops / min, and the fry actively eat the Artemia bait dripped into the seedling cultivation tank 6.

[0037] Step 7: Feed once in the morning and once in the afternoon every day. The total amount of Artemia should be controlled at 200g throughout the day.

[0038] Step 8: Continue feeding the fish for 3 months using the methods of steps 6 and 7 until the fry switch to bait and start to eat the feed.

[0039] Step 9: Clean the impurities in the burette 4 regularly to ensure the smooth flow of the pipeline and the feeding effect.

[0040] A device for taming the mouth opening of larvae of the thrush, comprising a bait tank 1, an aeration device 2, a burette 4 and a seedling cultivation tank 6;

[0041] The aeration device 2 is provided in the bait tank 1;

[0042] The bait tank 1 is connected to the seedling cultivation tank 6 through the burette 4. The seedling cultivation tank 6 is located below the bait tank 1. The burette 4 inputs the bait into the seedling cultivation tank 6 through siphon action.

[0043] Furthermore, the burette 4 is provided with a dripping bucket 3 and a flow valve 5 .

[0044] Furthermore, the aeration device 2 includes a motor 201, a main shaft 202, a sleeve 203, an impeller 204, a bearing 205 and a spiral blade 206;

[0045] The sleeve 203 is a hollow structure, and the outer side surface of the bottom of the sleeve 203 is fixedly connected to the impeller 204. The top of the sleeve 203 is rotatably connected to the top of the main shaft 202 through the bearing 205. The main shaft 202 is inserted into the sleeve 203. The top of the main shaft 202 is fixedly connected to the output end of the motor 201. The motor 201 is installed on the bait tank 1 through a bracket, and the spiral blade 206 is fixedly connected to the main shaft 202.

[0046] Specifically, the motor 201 can be installed on the bait tank 1 through a bracket to fix the motor 201. When the motor 201 is working, it drives the main shaft 202 and the spiral blade 206 to rotate. When the spiral blade 206 rotates, it generates a downward thrust on the air in the sleeve 203, thereby forming a negative pressure hollow chamber in the sleeve 203. The negative pressure hollow chamber introduces air from the top of the sleeve 203 and discharges it into the water body of the bait tank 1, thereby mixing the air with the water body to achieve the function of aeration. At the same time, under the friction of the bearing 205, the main shaft 202 drives the sleeve 203 to rotate slowly, so that the main shaft 202 and the sleeve 203 form a differential rotation, so that the sleeve 203 drives the impeller 204 to achieve the stirring function of the bait tank 1, so the aeration device 2 of the present invention can simultaneously achieve the two functions of aeration and stirring.

[0047] A specific embodiment is given below:

[0048] like Figure 1As shown, the bait tank 1 is placed next to the seedling cultivation tank 6, and the liquid level of the bait tank is higher than the water level of the seedling cultivation tank. The aeration device 2 is introduced into the bait tank 1 to ensure that the Artemia in the bait tank 1 is evenly dispersed, providing a basis for siphon feeding. One end of the burette 4 is placed in the bait tank 1, and the other end is placed in the seedling cultivation tank 6. The drip bucket 3 is squeezed so that the bait can enter the seedling cultivation tank 6 from the bait tank 1 through the burette 4, and then the flow valve 5 is adjusted to control the titration speed at 100 drops / min. At the same time every day, the siphon feeding system is turned on to feed the open-mouthed fish fry of the extreme edge flat pharyngeal tooth fish for 3 to 4 months until the bait is changed and the feed is started to be ingested, thus realizing the domestication process of the fry.
