As jifigz said, they’re going to be moving and spreading out as the water warms up. However, the water is still pretty cold. If you’re on the bottom, sometimes just letting it sit for a few minutes work. Also, the bite cane be quite subtle. You may only feel slight taps when they’re picking your bait up. Other times, they may be more aggressive on the take.
If you are fishing eddies, a rocky hard bottom is your best bet. If the eddie has a muddy bottom, not so good. You can tell that as you slowly pull your bait along the bottom.
Keep at it, you’ll get the hang of it. Good luck.
