Orientation Differences Between Populations of Juvenile Sockeye Salmon

British Columbia's Babine Lake system has three populations of sockeye salmon smolts which travel different routes to the outlet on their seaward migration. The objective of this study was to determine if the directional preferences of these populations are innately different. Smolts from five streams which contribute to the lake populations were raised from the egg in similar conditions and their directional preferences tested.
