For the catfish pouches, fish them on a simple bottom rig or bait holder setup and let the scent do the work.
Start with one flavor, then rotate if bites slow down or if one bait gets picked apart faster.
The giant Rapala-style items are display pieces; if used on water at all, they’re novelty floating crankbait-style lures for open-water casting or trolling.
When to switch
Switch to a different catfish bait when fish are ignoring scent, the water is very cold, or you need a stronger natural bait profile.
Switch away from the giant lure items if you want actual fishing performance; they’re better as decor than as everyday tackle.
