Chris, the Silvers the paper is talking about are resident fish. These fish are similiar to most of the winter Blackmouth, in that most of them never leave Puget Sound. If you have ever heard the term "net pen fish" these are the fish they are speaking of. The fish are kept in net pens for the first year of their life in the salt. Not leaving the confines of their net seems to keep them from their migratory urge. These fish are generally smaller than their ocean bound cousins. Although, the last few Septembers it has been difficult to distinguish between them.
