I thread minnows all the time for fishing. I make a 2-3 foot leader with a loop at one end Adan a #12 to 8 Treble hook at the other. I start right behind the Brain on the Minnow and poke just under the skin. Run the Needle parallel with the minnow just under the skin to the rear of the Minnow. Attach the loop end of the leader to the needle and feed the leader through the minnow.slide the shank of the hook just under the skin up to the barbs. When it is done the Minnow is swimming freely with the treble hook mostly hidden and laying tight to the Minnow.
I didn't know it was a race. It might take 30 Seconds extra to thread a minnow. I might kill one minnow to every 100 that i thread.
I have never fished for walleye through the ice and have only fished for eyes a few times from the boat, I have a question about catching eyes with dead minnows. Would a guy be best off threading the minnow like the posts here say and then setting the minnow on the bottom or holding it just off the bottom? We can't use live bait and was interested in any techniques to catch an eye. Do worms work good? Any info would be appreciated.
