I have utilized a concoction the past 4 years with considerable success.....take Puss n Boots and buy the pellet bait (they sell these pellets in most marina's in the HC) and you put these in a blender and blend them together (not puree), we stick them in gallon jugs and then take the plastic bait containers (may have to drill a couple of holes in the containers) and dump this stuff into them. It sometimes is a god awful smell, but, it works.
We have had no problem getting limits for a boat of 6-8 people every year. Good luck...
