Comments: Adults inhabit rivers and lakes.  Adults do not spawn every year but at least every other year.  With increasing age, the spawning interval increases to three, four and more years (Ref. 593).  Feed on invertebrates in the first year then switch to juveniles of pelagic fishes, e.g., <i>Oncorhynchus keta</i>, at age 3 to 4 yrs., kaluga feed on adult fishes (Ref. 40142).
