Understanding Lake Trout’s Eating Habits
When it comes to understanding lake trout’s eating habits, it’s important to consider several factors. Lake trout, also known as Mackinaw, are apex predators that primarily feed on smaller fish. They are opportunistic feeders that will eat whatever prey is available in their environment. The type and quantity of prey available in a particular lake will influence their diet. Let’s take a closer look at some of the key factors that influence what lake trout eats.
Water Temperature
The water temperature of a lake has a significant impact on the type of prey available to lake trout. In colder waters, for example, lake trout will feed on cold-water prey fish like ciscoes, whitefish, and sculpins. In warmer waters, they are more likely to feed on warm-water prey fish like yellow perch and suckers.
Time of Day
- During the day, lake trout are typically found in deeper waters and may feed on small fish, such as minnows, that are found near the bottom of the lake.
- At night, they will move closer to the surface and feed on prey fish that are more active in low-light conditions.
Seasonal Changes
Seasonal changes in the lake can affect the availability of prey fish, which can in turn impact the diet of lake trout. In the spring, for example, lake trout may feed on smelt during their spawning season. During the summer months, they may switch to feeding on perch and other small fish. In the fall, lake trout will often feed on salmon and trout that are returning to spawn.
Understanding lake trout’s eating habits can help anglers better predict where and when to find them. By taking into account factors such as water temperature, time of day, and seasonal changes, you can increase your chances of catching this elusive species.

Top Predators of Lake Trout
Lake trout are a key species in many North American freshwater ecosystems. As one of the top predators in these systems, lake trout help to maintain a healthy balance of fish populations. However, they are not the only predators in the water. Here are three other top predators that lake trout must contend with:
Northern Pike
Northern pike are a formidable predator that inhabit many of the same waters as lake trout. They have a long, streamlined body that allows them to move quickly through the water, and sharp teeth that make short work of their prey. Although they primarily feed on smaller fish, northern pike will readily attack larger fish like lake trout.
Walleye
Walleye are another popular sport fish that share the waters with lake trout. They are known for their large, reflective eyes that help them see in low light conditions. Walleye are typically smaller than lake trout, but they are also faster and more agile. They feed primarily on smaller fish and insects, but will occasionally take larger prey like lake trout.
Brown Trout
Brown trout are another species of trout that can be found in the same waters as lake trout. They are similar in size and shape to lake trout, but have a distinctive brown coloration with spots on their sides. Brown trout are known for their aggressive behavior, and will readily attack other fish in their territory, including lake trout.
Understanding the top predators of lake trout is important for anglers and conservationists alike. By knowing which species are likely to prey on lake trout, we can better manage these populations and ensure their continued health and survival.
Common Prey of Lake Trout
Understanding the diet of lake trout is crucial for anglers hoping to catch this popular game fish. Lake trout are known to be opportunistic predators, meaning they will feed on a variety of prey species depending on availability and season.
Some of the most common prey species for lake trout include ciscoes, whitefish, and crayfish. These species are often found in the same areas as lake trout and are a natural food source for them.
Ciscoes
Ciscoes, also known as lake herring or tullibee, are a common prey species for lake trout. These small, silvery fish can be found in many of the same areas as lake trout and are an important source of food for them. Ciscoes often school in large numbers, making them an attractive target for lake trout looking to feed on a lot of prey in a short amount of time.
Whitefish
Whitefish are another common prey species for lake trout. These fish are often found in deeper water, where lake trout also tend to reside. Whitefish are a relatively easy target for lake trout because they swim slowly and do not have many natural defenses.
Crayfish
Crayfish are a favorite food source for lake trout during the summer months when they are most active. These small crustaceans can be found in many of the same areas as lake trout and are often taken by anglers using live bait.
How to Imitate Lake Trout’s Prey with Lures
Lake trout are known to prey on a variety of fish species and other aquatic creatures. When trying to catch them, it is essential to use lures that imitate their natural prey. Here are some tips for imitating lake trout’s prey with lures:
First, consider the size of the lure. Lake trout feed on prey that are similar in size to their own body, so using a lure that matches the size of the target prey can be effective. Second, choose a lure that mimics the swimming action of the prey. Different species of fish and other prey move in distinct ways, so selecting a lure that replicates their swimming motion can make it more appealing to the lake trout.
Mimicking Small Fish
- Using a small crankbait or spinner that resembles a minnow or smelt can be a successful approach for targeting lake trout. The lure should have a realistic swimming motion and be retrieved at a slow and steady pace.
- Another effective technique is to use a soft plastic lure that mimics a small baitfish. These lures can be rigged on a jighead and bounced along the bottom to imitate a wounded or dying fish.
Imitating Larger Prey
- When targeting larger lake trout that prey on whitefish or lake herring, a larger lure that mimics their size and swimming motion can be effective. A large spoon or swimbait that is retrieved at a moderate pace can be particularly successful.
- For lake trout that prey on other bottom-dwelling creatures such as crayfish, using a jig with a soft plastic trailer that imitates a crawfish can be an excellent option. Jigs should be retrieved slowly along the bottom to mimic the movement of the prey.
Matching the Hatch
Finally, it can be beneficial to consider the specific prey species that are present in the lake you are fishing. Matching the hatch, or using a lure that imitates the species of fish or other prey that the lake trout are currently feeding on, can increase your chances of success. Pay attention to what is in the lake’s food chain and select your lure accordingly.
Seasonal Changes in Lake Trout’s Diet
If you’re planning a fishing trip for Lake Trout, it’s important to understand their diet and how it changes throughout the year. Seasonal changes play a significant role in determining what Lake Trout will be feeding on and therefore what kind of bait you should use.
In general, Lake Trout feed on a variety of prey, including smaller fish, crayfish, and insects. However, their preferred prey can vary depending on the time of year and water temperature.
Spring
In the spring, Lake Trout are often found in shallow water as they move in to spawn. During this time, they may feed on small baitfish like minnows and smelt. Try using lures that imitate these smaller fish.
As the water temperature warms up, Lake Trout may also start to feed on larger prey like suckers and whitefish.
Summer
During the summer months, Lake Trout often move to deeper, cooler water. They may still feed on smaller fish, but they may also start to target larger prey like ciscoes and lake herring. Try using larger lures that imitate these types of fish.
Insects can also become a more important part of Lake Trout’s diet during the summer months, especially in shallow areas with vegetation.
Fall
In the fall, Lake Trout start to prepare for winter and may feed more heavily to build up fat reserves. They may start to target smaller prey again, such as small minnows, as well as larger prey like whitefish and ciscoes.
As the water temperature drops, Lake Trout may also start to feed on crayfish, which become more active in cooler water.
- Overall, understanding seasonal changes in Lake Trout’s diet can help you choose the best bait and lures for your fishing trip.
- Pay attention to the water temperature and where Lake Trout are likely to be found during each season.
