Unexpected enrichment of antibiotic resistance genes in recirculating aquaculture effluents of rainbow trout (Oncorhynchus mykiss): microbial community assembly and mobile genetic elements as key drivers
Introduction Recirculating aquaculture systems (RAS) are increasingly used in intensive aquaculture because of their capacity to reduce nitrogen, phosphorus, and organic matter discharges. However, whether improved conventional effluent quality is accompanied by a reduced antibiotic resistance gene (ARG) burden remains...
