Do you love big bluegill?
Used to fish with grass shrimp years ago when the local bait shop kept them in stock. No one in my area has them any more. They were more effective a bait than anything else we fished including red worms. I now order wax worms on line to use and find them effective and cleaner to use than red worms but not as easy to keep alive for long periods.
I have begun to raise wax worms for bait and was pretty successful with it. I lost my last colony due to mold but just started three new colonies.
