美国麻省理工学院的科学家发明了一种利用超声波增强鱼类免疫功能的新技术.采用这种技术,能使鱼更容易接受疫苗、抗菌素和激素等,从而可减少鱼病的发生.多年来,渔民们通常是将鱼放入加有抗菌素或其他药物的水中,以增强鱼的免疫功能,但这种方法效果往往不理想.而如果同 Massachusetts Institute of Technology scientists invented a new method of using ultrasound to enhance the immune function of fish, using this technology can make fish easier to accept vaccines, antibiotics and hormones, which can reduce the occurrence of fish disease. , Fishermen usually put the fish into the water with antibiotics or other drugs to enhance the immune function of the fish, but the effect of this method is often not ideal, and if the same
