Salt water salmon fishing.

Tried and true salmon trolling tips.
If your not familiar with the area, drop in at a local tackle shop for directions to some of the hot spots and inquire about what's working.
My favorite method is trolling a cut-plug herring. A cut-plug is simply cutting the head of the herring off. This must be done in the following fashion to ensure the proper "action" or "roll" is achieved. Cut the herring at a 45 degree angle from top to bottom and also the width of the herring. This will give you a nice tight or small roll on your bait.
Next attach your flasher to the down rigger cable, 1 foot above the ball with a 3-4 foot leader. Note do not use a long leader or you will get tangled with your line.
Attach your release clip 18-24 inches above your flasher line, make sure your bait is only 4-5 feet behind your flasher.
The reason I like this setup is because the fight you will experience from the fish will be increased 10 fold. With Coho often the flasher will take 90% of the fight out of the fish. Try the above method and you will never attach the flasher to your rod again.
Other tips I can give you:
Try different trolling speeds: The speeds that have worked best for me range from 2.5 to 6 km per hour.
Look for bait balls on your fish finder, they will show up as a big red or black ball. When you find one and if you are fishing in a tide, turn your boat into the tide and adjust your speed so as you are stationary on top of the bail ball. The tide will work your bait/cut-plug for you and you will catch more fish than you could imagine.
Coho like fairly open water where as Chinook like to be close to shore.
Remember in Canada you must use barbless hooks when fishing for salmon!
Good luck and Good Fishing. Brady
