Abstract

The local migratory behaviour of lake trout, Salmo trutta L., and residentbrown trout, S. trutta L., progeny from an inflowing stream of Lake Constance was compared. No differences were detected with respect to emigration rate (3.5% and 4.2% for lake trout and resident trout, respectively), rate of residency (6.8% and 8.2% for lake trout and resident trout, respectively)and rate of survival (12.3% and 12.1% for lake trout and resident trout, respectively) one year after stocking. Some of the resident brown trout offspring became migrants and vice versa. The results indicate that the progenyof riverine brown trout contribute considerable numbers to lake trout stock.
