The returns indicate two lines of migration — the main one northerly into Clarence 
Strait, traversing this body of water to its junction with Behm Canal and also to its 
junction with Ernest Sound, and a minor one in a southerly direction from the point of 
tagging. Part of this latter migration crossed Clarence Strait to the Prince of Wales 
Island shore, where three fish were recaptured. The majority, however, followed the 
Gravina Island shore and then took an easterly course, scattering to various points
