I'm not sure what could be changed, but I just finished a week long fishing trip on the tff, and between 3 fisherman for a week, we ended up catching 26 walleyes, with just 1 or 2 fish being over 15 inches. Seems very odd to me, but it is just the 2nd time we have been to the tff, and we really arent experienced fisherman... so maybe we arent doing something right!
