因水产养殖动物生活在复杂的水环境中,而水体理化因子如:温度、盐度、酸碱度、氨氮和有机质(包括溶解和非溶解态)的含量,以及生物密度(生物量)等,都是影响药效的重要因素。一般认为,药效随盐度的升高而降低, Because aquaculture animals live in complex water environments, physical and chemical factors such as temperature, salinity, pH, ammonia nitrogen and organic matter (both dissolved and non-dissolved) and biomass (biomass) are all Affect the efficacy of the important factors. It is generally believed that the efficacy decreases with increasing salinity,
