Description of life cycle and mating behavior Mature adults migrate upstream in the summer and may cover as much as 1,000 km (Ref. 28219) to spawn over gravel in fairly swift water. After spawning, adults return downstream. Young probably hatch in the spring and descend rivers into estuaries (Ref. 27547). Coregonus autumnalis do not breed yearly (Ref. 28219, 28220).
