SMX and SDD residues were widely detected with the sul1 sulfa-resistance gene. Nine out of twelve sites had blaCTX-M, blaTEM, and blaSHV. Wastewater merge point of backyard-based aquacultures (Ri-E) had low diversity. Three genera of Polynucleobacter, Varivorax and Limnohabitans predominated at Ri-E. Aquaculture management may affect the diversity of backyard-based aquaculture.
