Is this sturgeon for real?

Not being a fisherman, I don't usually mention fish and fishing here, but this picture is an exception. It was passed on to me via three old newspaper colleagues of mine, Pat Pappas, Tim Whittaker and Peter Marsh. This sturgeon was caught and released in Lake of the Woods, near Kenora, a couple of weeks ago. It weighed in at over 1,000 lbs., measured 11'1" long, 56" in girth, and took 4 guys (taking turns) 6.5 hrs. to reel in. Apparently any sturgeon over 5' in length has to be released unharmed and cannot be removed from the water. Sturgeon over 5' are regarded as good brooding/breeding stock. The story goes that this great specimen was worn out from the fight to catch it, but was released shortly after the photo was taken.
In the Caspian Sea, sturgeons grow to 18' and 4400 lbs., but in Ontario,the record for Lake Sturgeon is just over 5.5' and 168 lbs, while the record in adjacent Minnesota is also 5.5' but only 94 lbs. So either this is the catch of the century or an hoax.
