the whitefish lives really deep in the cold water
most of the time, they don't even come to the shallow warm water
in the winter time, when the water freeze up
they move into the shallow water to search of food
because their food supply dried up, and shallow is cold enough for them
this is when we catch them
LIKE I SAY
THE REASON WHY YOU ARE NOT CATCHING THEM IS
BECAUSE YOU ARE FISHING OUT OF SEASONKEKEKE
