Maybe Augie can chime in here with his slot size and catch sizes to confirm this, but that is what I am saying. However, I have never targeted the larger panfish with my trap. I am basing it on the fact that I have caught several 1/3 pound fish with my 1-1/4 opening and these 1/3 pound fish were about an inch wide. That extra 1/4" allows them to enter without the fear of getting hung up. Mostly, my trap catches the smaller 2 to 4 inch fish with the 1-1/4 opening. You may find that you need to open the slit up a fair amount to catch the whoppers.
