Heh, first post too glib?
Best bet is to remember that almost all the salmon you see in a river you
CANNOT catch. They simply will not take anything. Some bright bulbs out West did some studies and found 9/10 salmon will simply swim out of the way of everything an angler can throw at them.
And that's in a perfect scenario, this is part of the reason for the fever of Salmon Insanity, the maddeningly frustrating truth that black boots won't hit. Anything.
Toss those super spooky, lived all their lives in 300' of water and now they are in a creek they can barely swim in, not eating only decomposing fish into a Lake O trib with everybody & their dog walking by and those 10% of fish that MAY hit just got a permanent case of lockjaw. Any sort of hardware or lure isn't going to work. Period. That's the hard cold truth of angling for salmon in rivers.
Salmon will occasionally eat the eggs of other salmon, so if they're not spooked you can drift the bigger pools & runs with a chunk of skein or single eggs. But most of the fish you catch will be lined, no matter how hard to try to avoid it.
If you want to throw lures instead of dealing with roe, but don't want to deal with pier loogans, find the deep holes in estuary water. The frog water between the mouth and first set of rapids is probably some of my favourite September fishing, they'll be a few salmon cruising around waiting for night to run up the river. Smaller wobbling lures like a Rapala Taildancer, Kwikfish, Wally Diver work, but it can be slow fishing during the daytime.
This is what an actual take looks like, drifting a loonie sized ball of skein around the frog water.
Bait hooked at the back of the mouth, not the outside of the jaw.
