Lake whitefish prefer cold, deep waters and are commonly found in large lakes and rivers
They tend to stay in areas with sandy or gravelly substrates, which are ideal for their feeding and spawning activities
Their diet mainly consists of aquatic insect larvae, mollusks, and small crustaceans, although they may also consume smaller fish and fish eggs
Lake whitefish are relatively sedentary, especially in large bodies of water where they exhibit minimal movement except for seasonal migrations
Lake whitefish migrate from deep to shallow waters in the spring and fall, returning to deeper areas during the summer and post-spawning period
Spawning typically occurs in the fall or early winter, often at night, when groups of fish rise to the surface to release eggs and milt
After spawning, they move back to deeper waters, and the eggs are left to develop on their own without parental care
In colder, northern regions, lake whitefish may spawn less frequently, sometimes only every other year
