The indiscriminate use of antibiotics in aquaculture has contributed to the prevalence of antibiotic resistant bacteria in aquaculture ponds and this represents a major challenge to public health. The aim of this study was to determine the antibiotic susceptibility profile of carbapenem-resistant Enterobacteriaceae from selected aquaculture ponds in Awotan area of Ibadan, Oyo State. Water samples from fifteen (15) concrete and earthen aquaculture ponds were collected weekly for a period of two months. Isolation of bacteria was carried out using the standard pour plate technique on MacConkey agar supplemented with imipinem. Pink colonies presumptive of members of the Enterobacteriaceae were purified and characterised using conventional methods. The isolates were subjected to ten classes of antibiotics using the Kirby Bauer disc diffusion technique.
