"Don't worry I used to be in the same position as you, only catching wilds, back when I first started fishing. But after years of figuring them out, I have zeroed in on just hatchery Coho and rarely catch wilds"....what a crock of S***! you can't be serious
Only way you could maybe stack the deck a little in your favour is to to avoid fishing high in the river (because the hatch fish may get thinned out as they go up) but I have cuaght plenty of hatch fish from allison up to the boundry. I have also hook 5 wilds in a roe near KW when 5 other guys each pulled in a hatchery fish each...its totally random/a fluke what you hook.
To suggest you can target hatch fish over wild is rediculous.
