The food supply certainly backs up the small head, overstuffed body. Good size/weight for sure.

One of the little "bows" I just caught in Francois Lake, BC, was stuffed as well - huge rounded gut. Once in the boat, he disgorged his gut full of Mayflies all over the bottom of my boat.LOL
Came home with some nice fish, though & in the freezer for smoking this fall.
