The scientific name for Lake Trout is Salvelinus Namaycush. It's also known by many other names such as Mackinaw Trout, Trout Salmon or Gray Trout with it's Cree Indian name being Touladi. It's actually not a trout. The Lake Trout is a char and it's closest relative is the Arctic Char, which both are indigionous species to North America and a major fishing target in Ontario.
Lakers are found in hundreds of fishing lakes in Ontario and even though they seem like a rare and elusive fish they are actually quite common in Ontario. The perception people have is based on not knowing how to fish for them or not spending any time fishing for them; a problem we solve on this fishing website. The best eating size Laker is 1/2 to 5 pounds. Stories about them being an oily fish are totally not true. They taste fantastic and are far superior in flavour to Rainbow or Brown Trout, which taste more like salmon.
Lake Trout are usually found in deep rocky lakes. Lake Trout are a cold-water species and in the summer they go deep to find cooler water. Many people seem to think they go to the bottom of the lake and are not accessible. Generally on Ontario's inland lakes the Lake Trout rarely go below 55 feet deep when feeding. They require a minimum dissolved oxygen level of 6 parts per million or greater to be actively hunting. Lake Trout can survive in lower oxygen levels but their bodies go into a state of hibernation and that does not interest fisherpersons. The boundary separating higher and lower oxygen levels is caused by different water temperatures and this is called the thermocline. Just above the thermocline is where the greatest number of feeding Lake Trout will be. They will shoot up into shallower water for short periods of time to raid schools of Lake Herring, Shad, Cisco and Chub. Early morning and evening you will find the best fishing depth to be around 40 to 50 feet. This is different on every lake. In spring fed lakes you can catch Lake Trout in 15 feet of water in the middle of summer.
Lake Trout Growth Rate
Lake Trout will grow 4 inches per year for the first two years and then 2 inches per year for the next six years. After that they will only grow ¾ of an inch per year.
Lets say a Lake Trout is 38 inches long.
A = 8 (first 2 years)
B = 12 (next 6 years)
C = 38 (length in inches)
D = .75 (growth per year after 8 years)
Age = A + B + ((C-(8+12))/D)
Age = 8 + 12 + 24
Age = a 38-inch Lake Trout on average is 44 years old on inland lakes.
Lake Trout on the Great Lakes can grow much faster than on smaller inland lakes.
Lakers can reach great sizes. The Ontario record is just over 63 pounds and was a world record for 39 years until broken in 1995 when a 72.5 pound Lake Trout was caught on Great Bear Lake in the Northwest Territories. Recently at Plummer's Lodge on Great Bear Lake there was a 78.85 pound Lake Trout that was caught and released and is the Unofficial World Record at this time. In 1961 a 102 pound Lake Trout was net in Lake Athabasoc and in 1998 a 104 pound Lake Trout was net in Lake Nipigon by the Ontario MNR, which makes it the largest Lake Trout every recorded. There are some bodies of Water in the province like the Great Lakes and Lake Nipigon, which produce Lakers just as big as Northwest Territories, Nunavut or the Yukon.
