Hi slicktrick,
All great advice on burbot here.
This video from Matity's GetFishing will also give you a bit more info on ice fishing for burbot during the spawn.
---->https://www.youtube.com/watch?v=zsYi8lV2JP4Burbot are a great fish to catch as they are good fighters and good eating.
They like the codfish you buy in the store, just a bit more chewy.
During the spawn burbot are quite aggressive and will hit most lures in their area.
Bang the lures the bottom to make lots of noise and get their attention, when they come over slow down a bit and give little twitches to seal the deal.
When the spawn is in full swing a person can sometimes catch large numbers of them, but, just like any other fish, the big females should go back to ensure the population stays healthy.
While burbot spawn is happening you may also catch whitefish or tullibee/cisco, who are in there eating the burbot eggs.
Pike are usually present as well, eating the burbot, cisco and whitefish.
Good Fishing.
