Hi All,
I rarely target whitefish directly in winter, preferring to sight-fish them with a fly rod when I do target them. I am, however, an avid pursuer of lake trout and burbot, and to a lesser extent pike.
In many lakes where I live, lake whitefish and round whitefish are one of the only bait fish for the apex predators. That being the case, I want to understand their winter movements to better pattern their predators.
What resources can you point me to regarding whitefish movements under the ice? What knowledge and experience can you share? I assure you, whitefish will not be harmed, only those who would harm them!
What I know, or think I know:
- Spawn around first ice on shoals – pike will chase them into shallow water. Some big trout that I’ve caught early season in shallow water match-up with this.
- Feed on crustaceans and insects predominantly, so will tend to work areas adjacent to littoral zones. As far as I can tell, whitefish like to feed along the bottom of the drop-off where there is a good littoral zone on the shelf.
- When summer fishing, I see them on the shoal on the lake side of a weed bed (as opposed to the shore-side) am I wrong about their use of the bottom edge of the drop-off?
- Will congregate where there is an inflow bringing a steady supply of nutrients to support their prey.
- I’m left wondering: how deep of water will they prefer? My impression is that if there are two flats below 40-50ft (transition from littoral to benthic) they’ll choose the shallower, if all else is the same.
- My impression is that they don’t suspend. Not that they won’t swim up to take a bait, but that they don’t cruise halfway up the column.
- I’ve observed that burbot usually first appear at the bottom edge of the drop off, but can be caught on the shelf in the middle of the night. Are they following whitefish in to the vegetation in the dark?
I realize no ‘rule’ can apply to every lake, but every bit of info helps!
Thanks for reading! - Gorf
