Will-eye, About bait for minnow traps, with my glass traps I use crumbled cracker crumbs. The cracker crumbs bleach out in the water and float around inside the glass trap I guess drawing the minnows attention, plus a slight scent or food trail too. I heard where those who use the wire traps use dry dog or cat food as bait because it stays in the trap better than crumbled cracker crumbs. I would imagine tying cracker crumbs in a piece of old panty hose like a bait bag would work too on the wire traps, kinda like biting a crab pot. Most of the time my glass traps are placed in small creeks for regular creek minnows and creek chubs. Just below riffles for regular minnows, and holes for the chubs. On the river I’ll place them close to or around the mouths of the creeks, and the downside of a long shallow tapering sandbar and mark with with a float bouy. A foot or two deep is enough. A small piece of driftwood works great for a float and doesn’t draw attention to your minnow trap. Also some of the upside inside corners of wingdams is a great place for the river shiners too. In rivers and creeks funnel end of your trap always placed down stream. In lakes I would try around sand beaches at night funnel end facing out towards the lake so the trap won’t roll if the wind and waves come up. Hope this helps.Terry
