1. Scientific Name

Lakers, Lake Charr, Grey Trout, Mackinaw and a range of other names all refer back to Lake Trout. However their scientific name is Salvelinus Namaycush and they’re a close relative to that of the Brook Trout.

In their natural wild habitat they live 10-20 years, drastically longer than Brook Trout. While 20 years in itself is long, there are reports of Lake Trout living to a whopping 60 years of age! It’s clear why they can reach such dramatic sizes.

4. Spawning

Alike their close relatives, Brook Trout, Lake Trout will spawn late September – mid December. However, unlike Brookies, they don’t prefer to spawn in rivers, although it does happen, they are more commonly known to spawn in lakes that have a rocky, boulder bottom. They eggs usually end up in cracks and seems between rocks where they’ll incubate over the winter and hatch early spring, typically March or April. Considering they are cold water dwellers, they spawn in water temperatures between 8- 13 °C (48-57 F).

5. Habitat

As previously mentioned, they are cold water dwellers and also strive clear water. Requiring cold water but not favoring rivers means they’re found in deep lakes where they can retreat to deeper, colder temperatures come summer. It is rare to find a healthy Lake Trout population in lakes that’re shallower than 50 feet (15 meters), hence why Lake Nipigon with it’s maximum depth of 540 feet (165 meters) is a perfect body of water for Lakers. In the spring when the water is cold Lake Trout stay at trolling depths, when summer comes and water temperature peaks, 20-40 feet of water suits their needs better.

6. Diet

Their food sources highly depend on the body of water they inhabit, corresponding to what is available to them. However, Lake Trout commonly feed on other fish species and aquatic insects. This includes, but is not limited to: smelt, whitefish and other juvenile fish species, water beetles, worms, leeches etc.

7. Bait & Lures

Depending on the time of year depends on the bait and technique to use. When the water is first opening up from ice melt and they remain shallow, using spinners with flashy colors is optimal. Once they move deeper, whether it’s trolling or downrigging depth, spoons are among the best lures to reach for. Common brands are Lucky Stride, Eppinger and Len Thompson. P.S everyone has had luck on a yellow and red Five of Diamonds! While trolling, Flatfish and Kwikfish are fan favorites! T-55 Flatfish are great examples. What makes the Flatfish and Kwikfish so irresistible to Lakers are the swim patterns, they have a wobble/bounce as they troll through the water making them noticeable. Flashy colors are always a no brainer for Lake Trout!

8. Appearance

While Lake Trout are not as flashy and vibrant as Brook Trout, they do encompass their own unique beauty. They can be light in color from silver and olive green to dark green, brown and merely black on the top sections of their back. Lakers always have a lighter colored belly, usually cream/white. Their fins are similar to the Brook Trout in terms of having the white outline on the ends of the fin, but do not have the black thin strip that divides the white between the reddish/orange color. Their side mid section is scattered with pale spots.

9. Lake Trout + Brook Trout = ?

Have you ever heard of a Splake? It is also a cold water dweller species that was introduced and naturalized in Ontario. A Splake is a cross between the Lake Trout and Brook Trout. They were stocked throughout Ontario in water conditions that suit Lakers better than Brookies. They do not reach the impressive Lake Trout sizes, however do get up to 10-12 pounds in proper conditions.
