Foraging mechanisms of age-0 lake trout (Salvelinus namaycush)

► Age-0 lake trout responded to prey similarly under all non-zero light levels tested. ► Age-0 lake trout had a longer reaction distance in response to moving prey. ► Mysids had an escape response that reduced foraging success for lake trout. ► Intake rate could be modeled as a function of mysid density. ► Maximum daily consumption could be modeled as a function of lake trout weight.
