Seaward migration of silver eels occurred at nights during autumn at decreasing water temperature. Maximum migration-rate occurred mid-October at medium and decreasing water discharge. Most eels descended in the first quarter of the lunar cycle, few eels descended at full moon. Most males and small females migrated earlier in the season than the larger females. The migration speed of silver eels in fresh water was independent of body length.
