Résumé :	For several years at a eutrophic lake in southern Bavaria (Staffelsee, 766 ha) waterfowl was hunted by up to 30 hunters for just one day in November. The number of Mallards and Coots that were killed was relatively high and increased during the years. The number of shot Coots was not related to the development of their abundance in November. During the hunting season 1996/97, however, hunting was not restricted to one day. Only few persons at a time hunted waterfowl on at least 15 days between September and late December. Parallel to the multiple hunting events no autumn peak of waterfowl could be recorded as in the years before. This indicates that the relatively high frequency of hunting influenced the seasonal dynamics of waterfowl using the stopover site. Group hunting during one day apparently causes less impact on waterfowl dynamics, but is noticed as a major disturbance by persons living around the lake. So hunters should inform the public in detail on the advantages of hunting for just one day a year according to the "wise use" concept.
