Effect of Vegetable Growth on Content and Composition of Antibiotics in Litopenaeus vannamei Pond Sediments in Crop/Aquacultural Rotation Process

Photodegradation remains the major pathway of antibiotic removal in natural ponds. This study introduced a new method growing vegetables on bottom substrate shrimp ponds to improve sediment quality. The aim was investigate effect vegetable planting photodegradation antibiotics. characterized levels pond during this phytoremediation process and investigated content composition with without crop rotation (traditional control), as well yields. results showed that total antibiotics (e.g., trimethoprim, oxytetracycline, norfloxacin) all aquaculture continuously decreased from 44.78 ± 4.07 μg/kg 18.80 2.26 pond. amount consistently ponds, rate decline did not greatly differ. However, oxytetracycline faster than control pond, presumably because altered microbial-community characteristics promoted degradation. In following year, there little difference norfloxacin or between two An increase trimethoprim much higher crop-growing sediment. It indicated system remediated ecosystem providing possibility increasing profits by winter idle period
