No question that since the introduction of downriggers trolling has taken over as the preferred method of sport fishing, but nothing beats mooching for a relaxing day.
Back in the days of yore we would rig the live herring with two #6 or 8 hooks, one through the nose, other through the back behind the dorsal. 8-10 feet of leader and 1 1/2 to 3 ounce of "mooching weights", (crescent shaped weight, eye on either end). Rods were limber 10 foot, the cadillac rods being Hardy 10's and 1010's. Reels were single action knuckle busters. Generally people anchored up when mooching, especially in crowded waters (hole-in-the-wall, Horseshoe Bay, Salmon Rock near Gibsons, or my old favourite, the A-frame at Pender Harbour).
Strip Casting, using the same weight style, rig a herring strip with a single #4 hook at the head of the strip, peel line off reel and let pile up at your feet, cast the bait out and let it sink, peel more line off as the rig sinks, let settle, retrieve and repeat as necessary. Could use a bait caster, or even a spinning reel, but they weren't made for salt water years ago. The strip should have a bevel cut at the front - most available strip for purchase is precut to a good angle (to fit into strip holders used for trolling).
Cut plug - use with same gear, tandem hooks but leading hook inserted from inside herring stomach cavity out through side. Use when motor mooching or when a bit of tidal action would impart roll to the plug.
For making cut plugs, stop at a tackle store and buy a plastic jig they should have for cutting the herring. The cut on the herring (or anchovy) is a compound angle, looked at from the side the cut bevels from the top of the herring to the bottom, and if viewed from above, it also bevels from one side to the other. A good "cut" will put a nice roll on the plug. It can be done by eye, but, while the old pro's could do it consistently, it's hard to master. Don't forget to use the point of your knife to clean the guts out of the plug.
Methods are not restricted to salmon. Good for rockfish, snapper, ling cod too. Probably a good area to practice on.

Good luck with the fishing and your recovery.
