If you make the powerbait into BB sized balls and dry them in the sun, they can be effective with bluegill, but you have to be able to see the bait to know when to set the hook.
A #24 size hook and a white thread wrapped around the hook for attraction, is all that is needed.
If you have the patience you can catch a large # of them, cut the head off, scale and, gut. Pack them into a jar, pint preferable and, place them into a pressure cooker at 8lbs for 30 minutes. The bones will cook up with the fish, do not add water, only a tea spoon of salt per jar.
After canning you can make some of the best fish cakes you have ever eaten.
