Zooplankton fed by juveniles mainly have rotifers and copepods. In the cultivation of bait, the composition of the bait biocommunities should always be checked to determine the laws of fertilization, to ensure that the species of the bait is suitable and the amount of bait is sufficient. Fertilization can be applied to inorganic fertilizers and organic fertilizers, and the application amount varies depending on the location of fertilization, salinity, temperature, season, and nutrient content in water bodies.
Juvenile fish stocking rate is 50,000 per 1/15 ha, and the expected survival rate is 60%. After the juveniles are stocked, they are fertilized once every 5 days until the 20th day. On the 20th day after stocking, powdered material (protein content 40% to 50%) was started and fed at a rate of 0.9 kg per 1/15 hectare per day in two feedings. On the 26th day, 10% of the powdered material was replaced with 10% of the broken material. In order to change juveniles from feeding powder to floating crushing material. Since then, the daily replacement rate has increased by 10% until the 35th day when the broken material reaches 100%.
