Ahh I'll share a handed down tennessee river recipe that seems to work good other places. Hot dogs microwaved or cooked until they are hard. then soaked in soy sauce, garlic, salt, and grape kool-aid. I know it sounds nasty but the cats seem to love it! May not help you any but hey it's worth a shot. also when you catch them on jugs do they seem to wind up in one spot on the lake? That may help give you an idea of where they are on the lake. good luck to you!
