In which environments do crayfish feature heavily in the walleye diet?
Answer
Bottom-dwelling or cooler-water systems
The walleye's menu is broad and adaptable, but certain prey items are linked to specific habitats. Crayfish are noted as featuring heavily in the diet primarily when the walleye are functioning as bottom-dwellers or when they are situated in cooler water systems. This preference suggests that crayfish are sought out when walleye are exploiting lower structure or when temperature conditions favor this type of heavier, high-protein meal over more pelagic or insect-based sources.
