The adaptation process lasts for 24-48h, external sound and light change are avoided, the female and male channa aurantiaca parent fishes are gradually adapted to the environment, and the female and male channa aurantiaca parent fishes are observed and familiar with each other through the second transparent partition plate 22. The preliminary work plays a main role in the success or failure of the subsequent pairing, and the pairing can be prepared when the basic states of the male and female orange channa are adjusted to be quieter.
Starting the temperature control system 5 and adjusting to a low-temperature gear, so that the temperature of the water body is reduced to about 15 ℃, the remarkable reduction of the activity of the male and female channa aurantiaca can be observed, at the moment, the first partition plate 21 is taken out, the rest area 11 is communicated with the pairing area 12, the male and female channa aurantiaca can enter the labyrinth type pseudo-nest 3 and begin to contact with each other, the aggressivity of the female and male channa aurantiaca with the reduced activity is reduced, the fighting probability is reduced, once the fighting condition occurs, the weak trend can rapidly get rid of the pursuit of the strong trend through the complex terrain of the labyrinth type pseudo-nest 3, the shelter is carried out for rest by the dark room 32 with a cylindrical structure, and when fighting between the female and male channelling parent fishes of channelling acia is basically stopped, the temperature control device is adjusted to the normal temperature of 24 ℃, so that the temperature of the water body is slowly increased. The activity of the male and female orange spot snakeheads is gradually recovered in the temperature rising process, the respective fighting phenomenon is normal at the moment, the weak part can still be hidden through the labyrinth pseudo nest 3, the weak part and the strong part can contact again to try to pair with each other along with the time, and the male and female orange spot snakeheads can be successfully paired basically through 4-5 times of contact in the device. The labyrinth type pseudo-nest 3 avoids the chase of the strong part of the female and male channa aurantiaca after fighting, and greatly reduces the injury probability of the weak part; in the traditional pairing process, once a fighting phenomenon occurs, female and male channa aurantiaca need to be manually separated, pairing can be attempted again after long enough recovery time, the labyrinth type pseudo-nest 3 is matched with the structure of the dark room 32 to provide sufficient shelter for the disadvantaged party, the female and male channa aurantiaca can naturally select proper time for re-mating after fighting, the workload of manual intervention in the pairing process can be effectively reduced, the energy consumption of feeders in the pairing process is reduced, and the pairing work is efficient and convenient.
