There are exceptions, around here it is very common to use set lines for burbot.

"you may only fish with a set line (an unattended line) in lakes of Region 6
& in lakes of Zone A of Region 7. You are allowed to use only one line with one hook (no smaller than 3 cm from point to shank - see below). Any game fish that you catch other than burbot must be released. Set lines must be marked with angler’s name, address and telephone number."
