Chumming up a spot with chopped shad for a couple of weeks, then drift a dead bait rigged on a quick strike rig, Years ago in fisherman did an artical on huge browns from marginal water typically too warm
yet these areas in tiny streams produced double digit fish on stickbaits and big inline spinners
huge fish are hogs and eat eat and eat, dead and dieing trout are easy food sources yet using trout or parts as bait isn’t legal, so perhaps a shad dyed and scented to look like a stocker trout?
the dyes are available, as far as smelling like a trout...I used to extract trout oil from trout scraps from cleanupsfor trapping purposes...scraps placed in an old ice chest (the kind with a spout) and a sheet of plywood cut to fit the inside of a chest...once I had saved enough scraps the fill the ice chest 1/3 full, I used a large box of kosher salt sprinkled over the scraps and placed the board over the mix, and place 4 bricks on the board
tilled the chest by tipping it on the edge of picnic table so the drainage would drip into a large glass jar (1gal widemouth pickle jar) that was covered with fine window screen to keep out flies
as the scraps got squished I would add bricks, best keep far from noses you don’t want to offend!
this takes time, keep it out of the rain, once the process runs its course ( at least a week) place the jar as is in a dry place to age
said oil injected in painted baits as well as scenting up with a squirt in a ziplock bag
lots of info on oil infused dead baits used in the UK for giant pike
