Subject: Determining fish size from photo
I am writing with regard to the photo you sent displaying an angler, Louis Spray, with a
most impressive muskie. The photo is reproduced on the following page. You ask if it is
possible to accurately estimate the length of the muskie based on the photo and the fact
that we know that the fisherman is 6' tall.
