Walleye season is closed here in Michigan and a buddy of mine caught a 17.8 lbs walleye that measured 34 3/8" Long. However he forgot to measure the girth. This was a fatty....I cannot locate a reproduction even close to this size to try and estimate the girth. What do you guys think would be an approximate girth for something like this? I am not a huge fish taxidermist so I am looking to the experts for your input!! Thanks.
