                        Biology
                        Found in clear, cold, deep water of lakes and tributary streams; occasionally found in brackish water in the Arctic (Ref. 5723).  Moves from lakes into inlet streams or from slow, deep pools into shallow, gravel-bottomed portions of streams to spawn (Ref. 27547).  Feeds on benthic invertebrates (Ref. 1998).  Young are preyed upon by other fishes and  fish-eating birds; while adults in spawning streams are taken by mammals, osprey and eagles (Ref. 1998).  Utilized as a food fish or as dog food (Ref. 27547).
