Quick Answer
Mergansers generally prefer fresh food sources such as aquatic insects, crustaceans, and small fish. They tend to forage in shallow water areas with abundant vegetation and rocky substrates. This behavior is crucial to understand when planning a successful merganser hunt.
Merganser Food Preferences
Mergansers are highly opportunistic feeders, which allows them to thrive in various aquatic environments. They primarily feed on small fish, such as trout, salmon, and whitefish, as well as crayfish, snails, and aquatic insects like mayflies and caddisflies. A study on Common Mergansers found that they consume an average of 1.4-2.3 pounds of food per day during the breeding season.
Hunting Mergansers with Fresh Food Sources
To hunt mergansers effectively, focus on areas with an abundance of fresh food sources. These areas often include shallow water sections with rocky substrates, submerged logs, or weedy vegetation. Mergansers can be seen diving in these areas, often from 5-15 feet deep, in search of their preferred prey. When hunting mergansers in these areas, use a shotgun with a 10-12 gauge load, firing at a distance of 30-40 yards to ensure a clean kill.
Cached Food Sources and Merganser Behavior
While mergansers primarily rely on fresh food sources, they will also cache or store food for later use. Caching behavior is often observed in mergansers during the fall, when they stockpile food in preparation for winter. This caching behavior can be beneficial for hunters, as it may lead mergansers to return to the same area in search of cached food. Understanding this behavior can help hunters locate mergansers in specific areas and plan their hunt accordingly.
