近年来,水产养殖中应用抗生素和其他药物越来越多。如挪威1985年使用了17吨抗生素,1987年则达到了48吨。据报道,挪威水产养殖用抗生素量超过了人、畜用量的总和。事实上,滥用抗生素的最严重后果是提高了细菌的抗药性。育苗过程中大量使用抗生素预防疾病是造成细菌抗药性增强的主要途径。另外,有些养殖单位在养殖时为预防疾病没病时也投喂药饵使后果更加严重。现在,最早用
In recent years, more and more antibiotics and other drugs have been used in aquaculture. For example, 17 tons of antibiotics were used in Norway in 1985 and 48 tons in 1987. It is reported that the amount of antibiotics used for aquaculture in Norway exceeds the sum of human and livestock consumption. In fact, the most serious consequence of abuse of antibiotics is increased bacterial resistance. The heavy use of antibiotics in the process of raising seedlings to prevent disease is the main way to increase bacterial resistance. In addition, some aquaculture units also feed bait to prevent the disease from becoming sick at the time of aquaculture. Now, the earliest use
