This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.
After putting out setlines for burbot yesterday (my first time trying, except through the ice) I checked the lines today and found three small burbot. I made several adjustments to make some of the lines longer and place them better in relation to the current. I'm excited to see what tomorrow brings!
