A rod longer than 6 ft can be difficult to manage; weighted jigs that resemble herring or anchovy are probably the lure of choice, tide changes are the best time to salmon fish, and choose locations with some current to avoid dogfish.
fyi. I am interested in forming a sub group in SKABC that does trips where fishing is one of the goals. The standard SKABC does not stop to fish; but such a group would make planned stops for fishing in route to a destination, whether its a day trip or multi-day. However, this year, I have little time for kayaking, so hopefully next year something can be organized.
