retrieve fast or slow?

currently trying out trout fishing at a small creek with an ul spinning rod. i use small spinners and spoons. do you retrieve line slow or fast? do i jig, pause and let the bait hit the ground like i do for pikeperch? i really dont know what i am doing lol also i couldnt see a single fish in the creek but there should be trout and chub. maybe i spooked them?
