Occurrence of antibiotics and antibiotic resistance genes in dismantled aquaculture environment of East Tai Lake and aquaculture environment of Yangcheng Lake
In this study,the occurrence of antibiotics and antibiotic resistance genes in dismantled aquaculture environment of Tai Lake and aquaculture environment of Yangcheng Lake was researched.The results showed that after the seine was removed,the concentration of antibiotics in Tai Lake decreased significantly compared with that in the aquaculture area.The concentration of 4 sites was varied form 0 ng/L to 9.70 ng/L.The concentration in the fish pond was 53.14 ng/L.The antibiotic concentration in Yangcheng Lake was 0～0.04 ng/L.However,the concentration of resistance genes in Tai Lake was similar to that in Yangcheng Lake.The main resistance genes in Tai Lake 1 site were ribosome protection genes,while the main resistance genes in Tai Lake 4,7,9,crab pond,fish pond and south,southwest Yangcheng Lake were antibiotic inactivation genes,and the main resistance genes in southeast Yangcheng Lake were antibiotic expection genes.
