A data compilation of antibiotic treatments in Canadian finfish aquaculture from 2016 to 2021 and the cumulative usage of antibiotics and antiparasitic drugs at marine sites.
Antibiotics can be introduced from aquaculture facilities into marine sediments where they may affect benthic communities and generate antimicrobial resistance (AMR). Antibiotics can be used in tandem with antiparasitics and the effects of their combined usage could affect AMR patterns and transmit...
