With all due respect my friend, if you are expecting this forum to fill your freezer you might be disappointed. There will be a lot of great tips in this forum, but if you really have no idea how to catch a salmon the self learning curve will be too long and too expensive. After spending a few hundred bucks on licenses and rods and reels and what nots, you'd start wondering if you are stealing from the little ones. I remember when I started off, each stocked trout I caught was costing me a couple of hundred dollars each.
What I suggest is go down to the river without any fishing gear and talk to guys fishing there. Start looking amazed, tell the folks that you've never caught a salmon before and they will talk to you. You will also get an idea of how easy or difficult it is. What ever you do, do not start buying gear before you take this step. My take, if you do not have a boat or if you have not started fishing as a kid or you do not have a friend who is willing to invest time on teaching you how to fish; you'd probably be better of buying your fish instead of fishing for them.
Hope I have not offended you.
Cheers
M
