DISEASE CONTROL METHOD FOR RECIRCULATING AQUACULTURE OF PLECTROPOMUS LEOPARDUS BROODSTOCK

The present disclosure provides a disease control method for recirculating aquaculture of Plectropomus leopardus broodstocks. The disease control method provided by the present disclosure includes water treatment, temperature control, air treatment, nutritional regulation, and biological control. The water treatment includes steps of allowing tail water of a broodstock rearing pond to flow through a balancing pond and a water collection pond to remove floating solid organic and inorganic compounds, and allowing residual wastewater to flow through a protein separation pond, a sand filter pond, a biofilter pond and a disinfection pond for treatment and recycling; the temperature control includes water temperature control using an air-source heat pump; the air treatment includes filtration of air in air-feeding equipment and ventilation pipes; the nutritional regulation includes regular feeding of a formula diet into the broodstock rearing pond; and the biological control includes rearing of Thais luteostoma in the broodstock rearing pond.
