一、用药浓度的灵活性用高浓度药物浸洗鱼种，应视水温、鱼的忍耐度灵活掌握．而常用药物剂量的选择，应在药物的安全浓度范围内。选择对病原体最低的有效剂量。1．针对不问的水温和水质．用药浓度应灵活变比。如我场一鱼池水深1．2米．面积1854平方米．由于水质较肥，曾每667 First, the flexibility of the drug concentration Dip the fish with high concentrations of drugs should be treated as water temperature, the flexibility of the fish to grasp. The choice of commonly used drug dosage should be within the safe concentration of the drug. Choose the lowest effective dose for the pathogen. 1. Targeted at the water temperature and water quality. Drug concentration should be flexible ratio. If my field a fish pond depth of 1.2 meters. Area of ​​1854 square meters. Since the water is fat, once every 667
