From what I have heard, salmon can and will stay in estuaries and even their natal streams longer. It may have something to do with the quality of habitat being so good that they don't have to move into the open ocean. Brook trout along the coast and great lakes will do the same. They will stay in the stream or near the mouth until the benefits of moving into open water outweigh the benefits of staying near home. Recent genetic studies have shown that it is a learned behaviour, not linked to a certain strain of fish.

I'm not up to speed with my knowledge of pacific salmon on the coast but if you try here [url=http://www.npafc.org/:e76ef]http://www.npafc.org/[/url:e76ef] you may get the answers you seek.

Also search for the Pacific Ocean Shelf Tracking (POST) project. They have been tracking salmon for the past 4 or 5 years with implanted computer chips (acoustic tags). There are receivers all over the pacific seabed that read the tags and send the data back. Its a really neat project.

I'd be interested to find out more.
