Met a driver out of Michigan while laying over in the 'Windy City' one weekend. Many hours spent over cup(s) of coffee ratchet jawing about ice fishing, thereafter.
On occasion Burbot fishing was the main discussion as was, the fish for dinner.
Truthfully, had I not experienced ice fishing and/or or used the cleaning methods described, I would have doubted the fish even existed.
To catch the fish through the ice, two methods were used. 1. A 'trout line' having an average of 8 ounces of weight and 8-10' leader was sent to the bottom than tied to a stick, laid across the hole through the ice. Snow was then piled over the opening, the location marked, than checked within 24 hrs. 'Fish on' or not required new bait and recover the opening til the next day. 2. Made use of a long pole (depending on DOW) to which leader and bait were affixed. The line end of the pole was pushed through the opening taking every thing to the bottom. Once again, snow was piled over the entire set-up and rechecked the next day.
Use of the heavy weight or pole is to keep the bait on the bottom as Burbot are bottom feeders.
Last I knew, PA. does not allow use of 'unattended' rigs for fish but, a heavy weight on heavy line and light leader sent to the bottom off of a 'tip-up(s)' might be worth a try.
As treesparrow says "they taste good if, your not the one cleaning them".
Cleaning requires the same methods used for cat fish.
Chili Pepper I gotta stick with the bourbon. Tried irish whiskey one time and by the end of the day........... I was taking back stuff I never stole.
