Siscowet tend to grow extremely large and fat and attracted great commercial interest in the last century. In human care, they receive a variety of fish, shrimp, and invertebrates as food. However, some individuals reach much larger sizes. Piscivorous lake trout grow much more quickly, mature at a larger size and are less abundant. Their populations have rebounded since 1970, with one estimate putting the number in Lake Superior at 100 million. In some regions, particularly warmer habitats, the fish must migrate during the summer to remain in cool, oxygen-rich waters. [13], Geneva, New York claims the title "Lake Trout Capital of the World," and holds an annual lake trout fishing derby. Unlike some other members of the Salmonidae family, they do not have anadromous tendencies, and live their entire lives in freshwater habitats. They spend their time in deep habitats in the open water. In their native range, overfishing and pollution impact this species to varying degrees. They start eating other fish much earlier than natural Trout species and grow much more quickly as a result. An 8" lake herring regurgitated by a Simcoe lake trout. (adsbygoogle = window.adsbygoogle || []).push({}); Animals.NET aim to promote interest in nature and animals among children, as well as raise their awareness in conservation and environmental protection. Because it reaches such large sizes, you must house it in an incredibly large tank. Commercial fisheries still exist in some areas of the Great Lakes and smaller lakes in northern Canada. Common lake trout tend to stay in shallower waters, while siscowet lake trout stay in deeper water. Other variations found in East Cree are kûkamâs[h], kûkamâw and kûkamesh. Notwithstanding differences in abundance, the density of biomass of lake trout is fairly consistent in similar lakes, regardless of whether the lake trout populations they contain are planktivorous or piscivorous. The specific epithet namaycush derives from namekush, a form of the word used in some inland Southern East Cree communities in referring to this species of fish. The eggs take between four and six months to hatch. The word trout is also used as part of the name of some non-salmonid fish such as Cynoscion nebulosus, the spotted seatrout or speckled trout. Mysis relicta)[7]. The Lake Trout is a species in the Salmonidae family. In these lakes, lake trout take on a life history known as planktivory. Humans have not domesticated this fish in any way.

Lake trout (Salvelinus namaycush) is a freshwater char living mainly in lakes in northern North America. Other variations found in East Cree are kûkamâs[h], kûkamâw and kûkamesh. Not to be confused with the brown trout, which some people refer to as the “Lake Trout,” this species hails from a different taxonomic genus. [citation needed], In Lake Superior, common lake trout (S. n. namaycush) and siscowet lake trout (S. n. siscowet) live together. Lake trout in planktivorous populations are highly abundant, grow very slowly and mature at relatively small sizes. Some lakes do not have pelagic forage fish during the period of summer stratification. Commercial fishing by Ojibwe for Lake Trout in Lake Superior is permitted under various treaties and regulated by the Great Lakes Indian Fish & Wildlife Commission (GLIFWC). Siscowet numbers have become greatly depressed over the years due to a combination of the extirpation of some of the fish's deep water coregonine prey and to overexploitation. "[8], Lake trout are known to hybridize in nature with the brook trout; such hybrids, known as "splake", are normally sterile but self-sustaining populations exist in some lakes. Some of its relatives include the salmon, char, grayling, whitefish, and more. [12] Similar cognate words are found in Ojibwe: namegos = "lake trout"; namegoshens = "rainbow trout", literally meaning "little lake trout". "Looking at what has happened in the lake and the results of computer simulations, it is clear that lamprey control needs to continue if Lake Superior is to keep its lake trout. The majority of its populations live in Canada and Alaska, though some also naturally extend into the contiguous United States. The largest caught on a rod and reel according to the IGFA was 72 pounds (33 kg), caught in Great Bear Lake in 1995 with a length of 59 inches (150 cm).[6]. Though the IUCN has not assessed this fish, invasive species, pollution, overfishing, climate change, and other factors all impact regional populations. The young fish, known as fry, continue to hide in the gravel for some time before moving into deeper water to hunt for prey. Its fins have a dark orange coloration and a thin white edge. As males begin spawning, they develop a dark colored stripe on the sides of their bodies. [14], Berkes, Fikret and Marguerite MacKenzie. Adults of this species live solitary lives outside of breeding. Professor of zoology at the University of Wisconsin-Madison, James Kitchell, credits effective constraint of commercial fisheries and persistent sea lamprey (Petromyzon marinus) control for the successful recovery of Lake Superior's lake trout. The juveniles hunt for plankton, insects, insect larvae, worms, and more. It is also very late to mature. There are 65-85 pyloric caeca in the hybrid versus 93-208 in the lake trout and 23-55 in the brook trout. This makes it quite impractical to keep this species in a home aquarium. This fish has a number of interesting traits and adaptations. They also range into deep water rivers as well. Learn more about what makes this species unique, below. During spawning, the females release their eggs, and the males fertilize them externally. This species has dark colored scales, with a light-yellow abdomen, and light-colored speckles across its flanks. A maximum recorded weight of 102 lbs. Trout is the common name for a number of species of freshwater fish belonging to the genera Oncorhynchus, Salmo and Salvelinus, all of the subfamily Salmoninae of the family Salmonidae. Splakes (hybrid fish, crossed between lake trout and brook trout) have also been successfully introduced widely in many areas of North America. As breeding season arrives, the fish move into favored spawning areas. However, humans have introduced this fish to other regions of the United States, as well as South America, New Zealand, and Sweden. Dietary preferences vary based on the age of this fish. Adults eat sculpin, alewives, smelt, minnows, and other small fish. Common lake trout (also called "lean" lake trout) are slimmer than the relatively fat siscowet. Splake are a cross-breed of a male Brook Trout and female Lake Trout. Naturally, this species lives throughout northern North America. Lake trout inhabit cold, oxygen-rich waters. [2], From a zoogeographical perspective, lake trout have a relatively narrow distribution. [3] Lake trout have been widely introduced into non-native waters in North America[4] and into many other parts of the world, mainly Europe, but also into South America and certain parts of Asia. Recommended Equipment: Bait-casting or spinning rods ranging from medium to heavy action and between 24 to 50" long.Both mono-filament and non-stretch super lines can be used. 10 to 15lb fluorocarbon, mono-filament on a spinning reel or on a bait-casting set-up works well. [5], Lake trout are the largest of the chars; the record weighed almost 102 pounds (46 kg) (netted) with a length of 50 inches (130 cm), and 15–40-pound (6.8–18.1-kilogram) fish are not uncommon.
