How many people are keeping walleye, regardless of what size they are? It makes perfect sense that the average size should increase with an increased size limit.
they could have been ignorant and thought they were saugers /saugeyes? no limit on those still. you'd get the same meat off 10-12" eyes as you would a perch that size.
If the average life span of a walleye is around 15-20 years why would you think ours in Indiana are only making it 5-6 years? I have no idea if the size limit is helping but it surely isn't hurting anything other than number of legal fish being caught. Which seems like at some point should turn the corner if the fish in the body of water are reproducing.
what does he charge Roe? I heard he was guiding people up there.
