Attenuation of the cortisol response to stress in female rainbow trout chronically exposed to dietary selenomethionine

► Trout exposed to Se-Met had greater concentration of cortisol compared to controls. ► Transcript abundance of mc2r was greater in trout exposed to Se-Met. ► Trout exposed to Se-Met had a reduced cortisol response to a handling stressor. ► Cortisone concentration was greater in Se-Met exposed trout...
