Lake trout in planktivorous populations are highly abundant, grow very slowly and mature at relatively small sizes. In these lakes, lake trout take on a life history known as planktivory. Some lakes do not have pelagic forage fish during the period of summer stratification. There is the Common Lake Trout (Salvelinus namaycush namaycush), the Siscowet Lake Trout (Salvelinus namaycush siscowet), and the less common Rush Lake Trout (Salvelinus namaycush huronicus). Three subspecies of Lake Trout are accepted. Many native lake trout populations have been severely damaged through the combined effects of hatchery stocking (planting) and over harvest. ![]() Populations are extremely susceptible to overfishing. The lake trout is a slow-growing fish, typical of oligotrophic waters. They are pelagic during the period of summer stratification in dimictic lakes, often living at depths of 20–60 m (66–197 ft). Lake trout inhabit cold, oxygen-rich waters. Ĭommon Names: Mackinaw, Lake char (or charr), Touladi, Togue, Grey trout, Siscowet, Paperbelly and Lean Brown trout and atlantic salmon look very similar. Wild brown trout may have bright red and orange spots and an orange adipose fin. The lower fins are typically brown, tan or nearly colorless and may have a white leading edge. ![]() Ĭommon Names: Brown, Brownie, English Brown Trout, European Brown Trout, German Brown Trout, German Trout, Lochleven Trout, Von Behr Troutīrown trout have a light body with dark spots. Stocked brook trout are typically less colorful than wild brook trout. The lower fins are typically red-orange with a white leading edge. If we forgot a fish please let us know.Ĭlick a species name to jump to a description:Ĭommon Names:Aurora Trout, Brookie, Coaster, Common Brook Trout, Eastern Brook Trout, Mountain Trout, Mud Trout, Sea Trout, Speck Troutīrook trout have a dark body with light spots and a worm-like pattern on back, head, and sides. Also, a photo of a fish in the water is very hard to properly identify. We all want to be in the photo with our catches but that makes identifying a fish very difficult if the photo does not show proper details. When submitting photos for identification help, try to have a close up of the actual fish. If submitting a photo for identification, please include the location that the fish was caught in (body of water, town and state). If you have caught a fish or have a picture of a fish you cannot identify feel free to submit a photo to us and we will give you a hand. These natural waters are home to the valuable species listed below.Freshwater Fish Identification Below is a complete list of freshwater fish found within the Northeast accompanied by a clear photo and description of the fish. Fortunately, concerted efforts to conserve the diversity of these vital water bodies continue to receive both federal and voluntary support. As a result, a handful of fish species are threatened and endangered. ![]() It is practically surrounded by water on all sides!ĭespite the obvious importance of the state’s freshwater systems, many of them are in danger of being ecologically altered due to anthropogenic activities. To say that the state of Illinois is “well-watered” does justice to its favorable position on the US map. Moreover, some of these streams consistently deliver essential nutrients and fish communities to the Mississippi River. Some of Illinois’s most diverse stream systems include tributaries that flow into one of the most important lakes in all of North America – Lake Michigan. Both surface waters and ground waters flow into biologically significant aquatic systems, many of which house a unique ecology of native flora and fauna. With over 100,000 ponds and lakes, it is a haven for countless aquatic species. Rife with freshwater resources, Illinois has thousands of clean streams and rivers extending throughout the state and over its borders on all sides.
