We have quite a few different species of whitefish in AK. The round has to be the most common, but the humpback whitefish is by far the biggest! There's a skin mount humpback on the wall at Fish and Game's office in Fairbanks that is over 14 lbs. THis beast is all body and no head, not to mention a huge "hump" on it's back. I think most folks would assume it's a carp!
