Six precautions for catching adult fish during high-temperature periods
Production practice has proven that catching adult fish during the hot season should be done at night or in the early morning (before dawn), when the temperature is relatively lower, which helps keep the fish fresh. When catching, the following points should be noted: 1. If using a seine net to catch, preparation work should be done during the day, clearing away debris on the water surface of the fish pond that hinders seining. 2. If using a soft vinylon fishing net, the height of the net should match the water depth of the fish pond as closely as possible.

Swordtail Fish Breeding Methods and Precautions Explained
Swordtail fish are ovoviviparous fish. Swordtail fish have very strong reproductive capacity. At 6-8 months of age, they enter sexual maturity. The male fish begins to chase the female fish, mating with her using the gonopodium to complete internal fertilization. The fertilized eggs hatch into fry inside the female fish's body and are then expelled. Swordtail fish are easy to breed and require no special management. When breeding, select broodstock over 5 cm, with a male-to-female ratio of 1:1 or 2:1. Lay more soft-leaved aquatic plants on the bottom of the tank and feed plenty of live bait. After the female fish becomes pregnant, her abdomen begins to swell and dark gravid spots appear. At this point, the male fish should be removed.

What are the precautions for artificial pollination of Gastrodia elata
①Attention must be paid to the timing of pollen maturity; artificial pollination can only be carried out when the pollen is mature, and immature pollen must never be used for artificial pollination. ②A large needle can be used to pick up and place the pollen, but do not pierce the ovary at the base of the flower. ③Cross-pollination must be used, especially pollination between flowers of different plants of different varieties, because the seeds produced this way have strong vitality, a high propagation coefficient, and the offspring have strong disease resistance and cold resistance. ④Artificial pollination is most suitable when there is mucus on the stigma of the pistil. Pollen placed on the stigma
