Trapping them yourself is probably the best if you have access to creek.
I've used them for years,there great for bass & stripers. Shad will always get the nod in my boat but, chubs are way more durable!
Once upon a time there used to be an older fellow down off hwy 52 just east of celina that would trap and sell chubs. Milt is or was his name. I bought chubs off of him for years. Anybody know who I'm talkin about?
