Here is a link to a picture of a 34" ice fished walleye from Lk Erie.
That walley will give the Herman's something to 'shoot for' to grow a walley to 34".
http://www.iceshanty.com/ice_fishing/index.php?topic=260591.msg2884203#msg2884203Actually I prefer my walleye to stay in the smaller size ranges of 12"-16" because then they are forced to eat the more abundant smaller sized forage fishes and not larger harvestable perch. Note the mouth size of the big walleye above. What do you think it has been eating on a regular basis - not 3"-4" shad?
