Embodiment 1
[0040] To use a circulating water track-type shrimp farming system, you first need to wash and disinfect the pond and enter the water. Fertilizer water: Put 120kg of mullet in the culture system (the culture density is 3kg / m 3 ). Feed mullet 3 times a day according to 1-3% of the biomass of the mullet, and sprinkle glucose every day to cultivate biological flocs. The water quality (DO, T, pH, ammonia nitrogen, nitrite nitrogen, and nitrate nitrogen) of the fluidized bed inlet and outlet water and the runway is measured daily. After 2 weeks of fertilizing water, use seawater to gradually adjust the salinity of the water body to 10‰, which lasted for a week, and then removed the mullet. During the fertilizer and water period, add 150g of crushed prawn feed and 100g of glucose to the floc culture device every week, add water to the culture pond, and aerate for a week. After the flocs are matured, they are discharged into the culture pond.
