Microsatellite DNA analysis and statistical assignment methods were implemented to identify the origin of 190 farmed escaped Atlantic salmon recaptured over a period of 2 months at a netting station located in Trondheim fjord, Norway. Samples were also collected from farms within the region. The escapees originated from a minimum of two sources, separated in time of capture at the netting station. The majority of the escapees captured in the early period probably originated from a single farm within the region, while escapees captured in later period probably originated from multiple farms, including from outside of the region. Biological data from the escapees supported these conclusions. This study serves to exemplify the use of genetic methods to assist fisheries management.
