Here is tip #4 from OutdoorCanada.com.
"Most provinces permit ice fishing with two lines, so why not maximize your chances by offering something different on each line? When chasing crappie and perch, rig one line with a tiny, 1/32-ounce jig tipped with a maggot or wax worm, and the other with a bigger, more colourful, 1/16- or 1/8-ounce jig tipped with a lively emerald shiner hooked lightly through the lips. For walleye and sauger, drop a lively minnow tethered to a jig down one hole (use a tip-sensitive deadstick rod hanging over a pail) and aggressively jig a spoon or swimming jig in another. With pike, set out a foot-long, freshly killed ciscoe or sucker on a quick-strike rig in one hole, then jig a spoon in a second hole. Finally, for lake trout, jig with a rod in each hand—one baited with a white, scented Exude or Berkley Power tube on a 1/8- to 3/8-ounce jig (the best winter lake trout combination) and the other rigged with a Williams spoon or airplane lure. When you jig with two rods like this, you can increase your odds of success even more by working different depths."
