[0028] 1) Acquisition and cultivation of discs: At the end of April, the indoor water temperature was raised to 14°C, and high-quality polyps preserved at 7°C were selected, and the temperature was rapidly raised to 20°C at a rate of 2°C per day to induce the polyps to split reproduce. Both the amount of feeding and the amount of water exchange increased during the period of polyp transverse cracking, and the water was changed by 50% every day. After two weeks, discs were released intensively, and each polyp released 5-10 discs.
[0029] The newborn dish-shaped bodies are cultured with micro-inflating, and after 3-4 days they develop into jellyfish larvae, they are then inflated with large air bubbles, and in 18 days they develop into juvenile stings with an umbrella meridian of about 20 mm. The feeding amount should be 1 hour full of food in the stomach and the density of Artemia nauplii in the water is 10-20 / L.
