From: Perturbation and restoration of the fathead minnow gut microbiome after low-level triclosan exposure
Experimental design of triclosan exposure experiment. Fathead minnows were exposed to low (100 ng L−1) or high (1,000 ng L−1) levels of triclosan, solvent (methanol), or control (no extra chemicals) solutions for 7 days. Multiple fish were housed in each jar, and two fish gastrointestinal tracts were sampled from each jar for microbiome characterization immediately after exposure (day 7) or after 1 and 2 weeks of depuration (day 14 and day 21). Eight fish gastrointestinal tracts were also sampled prior to the acute exposure (day 0).
