Arctic Lamprey (Lampetra camtschatica)
Uses

In Alaska, anglers may dig through mud for juvenile Arctic lampreys to use for burbot bait, while harvest of adults occurs during subsistence fisheries. Arctic lampreys are captured using scoop nets or an eel rake, which consist of a long spruce pole with nails through the end so the sharp nail ends stick out like a rake. They are dried, smoked, or canned mostly for human consumption or dog food.
