Diet with diphenyl diselenide mitigates quinclorac toxicity in silver catfish (Rhamdia quelen). [PDF]
PLoS One, 2014 In this study, the protective effects of diphenyl diselenide [(PhSe)2] on quinclorac- induced toxicity were investigated in silver catfish (Rhamdia quelen). The fish were fed for 60 days with a diet in the absence or in the presence of 3.0 mg/Kg (PhSe)2. Animals were further exposed to 1 mg/L quinclorac for 8 days.
