I think this laker is a pretty good representative of the red-fin morph of Great Slave lake trout. Characteristics include enlarged, bright red pectoral, pelvic and anal fins, and noticeable overbite. On the left side of the photo is a piece of the famous Utsingi Point -- the terminal point of the 100-mile long Pethei Peninsula.
The fish was a nice catch on a trip that featured otherwise fairly disappointing fishing. We were hunting for trophies but I was the only of the three in our party to land a trout over 40 inches long -- this 40.5 incher. Kind of skinny and certainly less than 20 lbs.
