Question 3

Describe walleye feeding habits.

Answer 3

They feed near the bottom at night where they move into shallow areas to feed on fishes, other small vertebrates, and invertebrates due to their eyes that are well-suited to the dark; this is also why they are usually in deep water during the day though they can sometimes also be found in very heavily vegetated areas during the day.
