Before the release of the spoonbill, it must go through the seedling cultivation stage. First, it takes 1 month to cultivate the newly hatched fry into 5 cm fish. The seedling cultivation pond is a mud pond with flowing water, with an area of ​​about 10 square meters and an oxygen-enhancing head. 500 fry are released per cubic meter of water. In addition to feeding on zooplankton in the water, the fry should also be fed with bloodworms appropriately. The water temperature should be controlled at 20℃-24℃, and the dissolved oxygen should be above 5 mg/L. Pay attention to cleaning and keep the water clean. After the fry grows to 5 cm, they are divided into ponds with coarse ponds. The coarse ponds are about 10 mu and 1.5 meters deep. The ponds must be disinfected and fertilized to cultivate a large number of zooplankton. 1000-1500 fry are released per mu. Pay attention to frequent water changes and start the aerator. After 30 days, they can grow to 10-15 cm.

Large water bodies such as mountain ponds, reservoirs and lakes have sufficient dissolved oxygen and the water temperature is not high in summer, which is most suitable for breeding spoon sturgeons. About 5 sturgeons are released per acre, and individual commercial fish weighing 2 kilograms can be caught in a year.

In the summer, nylon shade nets can be used to reduce sunlight in pond farming and keep the water temperature below 27°C. When the spoonbill is used as a supplementary species, 20-40 fish are released per acre, and silver carp that feed on phytoplankton are appropriately raised to control the water quality. After 10 months of farming, the individual can reach 1-1.5 kg; when the spoonbill is used as the main species, 200-250 fish are released per acre, and 150 other suitable fish species can be added. The feed is mainly zooplankton, so it is necessary to frequently add mixed compost and sprinkle soy milk for reproduction, and add some compound feed appropriately. After one year of farming, the individual can reach more than 1 kg.
