Description of life cycle and mating behavior Spawning occurs at night (Ref. 10242, 10344, 28849). A female and one or more males rise to the surface, release eggs and milt and descend separately toward the bottom (Ref. 27547). Spawning fish are very active and may leap completely out of the water (Ref. 1998). Breeds annually in the southern parts of the range, but only every other year or even every third year in the arctic and sub-arctic regions (Ref. 3757).
