Further, the length of the selected mandarin fish fries is 2.9-3.1 cm (about 3 cm), and the weight of the selected mandarin fish fries is 0.29-0.31 g (about 0.3 g).
As can be seen from the above description, the mandarin fish fries with the size smaller than the specification have low survival rate and poor domestication effect when the mandarin fish fries with the size larger than the specification are selected as domestication objects, so that the cost is greatly saved and the resources are also saved.
Further, an aeration device is arranged in the domestication area of the domestication pond, and in the implementation process of the steps 2 to 5, the aeration device is started to form an ascending water flow.
As can be seen from the above description, in the implementation process of steps 1 to 5, an aeration device is used to form a rising micro-water flow (rising water flow) to delay the sinking time of the iced fresh bait fish, the soft pellet feed and the hard pellet feed and prolong the feeding time of the mandarin fish fries.
Further, after the baits or the feeds are fed in the steps 2 to 5 for a period of time, the light and the aeration device for attracting are closed, the water dripping is stopped, the energy is saved, and then the rest of the feeds or the baits are fished out, so that the water quality pollution to the domestication pond is reduced.
Furthermore, the flow velocity of the ascending water flow is 0.05-0.1 m/s.
According to the description, the rising flow rate is controlled to be 0.05-0.1 m/s, so that the sinking speed of baits or feeds can be effectively delayed, and the phenomenon that the mandarin fish fries are washed away by water flow too urgently to influence the feeding of the mandarin fish fries is avoided.
Further, the induced light in the steps 2 to 5 is yellow light, and the intensity is 1500-2500 Lx.
As can be seen from the above description, the yellow light is adopted, and the intensity of the light is controlled to be 1500-2500 Lx, so that the trapping effect is better.
Further, the hard pellet feed in the step 5 is a fry opening feed with the crude protein content of 60% and the fat content of 8%; the particle size of the hard pellet feed in step 5 is 3.0 mm.
Further, in the period from step 2 to step 4, when fresh bait fishes or ice fresh bait fishes are fed, protozoa killing and bacterial tail rot prevention are carried out on the water body of the domestication pond once every five days.
