Zote soap. Big, pink bar of soap that has a high percentage of animal fat. I've been using chunks about the size of a sugar cube.What do you mean you use soap? What kind of soap and how big do you put a chunk on?
All I've caught is small channels. Biggest was maybe 6lbs. But honestly, I prefer the 1-2lb fish anyway. They skin easily, and the filets are a nice size.
