Yes,we have been sorting through the fish and usually just keeping fatter 17" fish.Those skinny 15" filets are not any bigger than a jumbo perch.Have also been some discussion about sorting through keeper walleye,with some people opposed to letting 16" fish go,due to fact they may not survive.That would also pertain to people "fun" fishing after they caught their limit.There was a heated debate on another site on that subject that elaborated about rules the ODNR interpet when you cull fish in a livewell.The survival of released fish was also debated.
