Identification: Brook trout can be distinguished from other members of the trout family by the dark, wavy, worm-like line on their back and the white leading edges of their fins, including the tail.
Common Name: Brown Trout
Other Names: German Brown Trout, Brownie, Loch Leven Trout, Saibling
Origin: Introduced Identification: Usually coloration is light brown or tawny with pronounced black spots on the back, sides and head. Spots areoften surrounded with reddish halo, along with reddish spots on the sides. Color is highly variable and browns are occasionally confused with landlocked salmon.
Common Name: Lake Trout, Togue
Other Names: Laker, Grey Trout, Mackinaw
Identification: Lake trout have a typical trout-shaped
body covered with light spots on a darker background of green or grayish brown. They are closely related to the brook trout, but lack thebright coloration and can be distinguished by a deeply forked tail.
Common Name: Landlocked Atlantic Salmon
Other Names: Sebago Salmon, Quananiche
Identification: Adults are generally silvery with a
slightly forked tail and small X-shaped markings on the back and upper sides. Juvenile salmon have a dark red spot between each pair of parr marks. Mature males develop a "kype", or hooked jaw, during the spawning season.
Common Name: Splake (from speckled trout and lake trout)
Other Names: Wendigo
Origin: Hatchery Hybrid
Identification: Splake and brook trout have very
similar coloration patterns, making it very difficult for the untrained eye to distinguish between the two species. Splake tend to have a slightfork in the tail, a trait passed down from its lake trout parent, whilebrook trout tend to have no fork or "square" tails.
Common Name: Rainbow Trout
Other Names: Bows
Identification: Coloration is highly variable
depending upon size, sexual condition, and habitat. Dorsal surface ranges from a greenish yellow to a blue-gray color with silvery colored sides; and the belly area is white to pale yellow in color. Large numbers of relatively small black spots occur over the whole body, but spotting is generally heavier along dorsal areas. Rainbow trout are often recognized by a vague pink to prominent red colored band, which extends from the cheek to the base of the caudal fin.
Common Name: Landlocked Arctic Charr
Other Names: Charr, Blueback Trout, Silver Trout, Sunapee Trout, White Trout
Identification: The charr is a slender member of the
salmon and trout family. Usually dark on the back, lighter on the belly, and having light spots on the sides. Paired fins are orange to red with a bright white leading edge. Tail is moderately forked. During breeding season, both sexes become highly colored. Coloration can then range from pink to orange bellies, blue to brown backs, and creamy to orange spots. Fin colors can also become very intense during spawning.
Common Name: Cusk
Other Names: Burbot, Lawyer Fish (Great Lake states), Freshwater Cod
Identification: Cusk have an elongated body with a
broad, flattened triangular head. The mouth is large and wide. A single chin barbel adorns the lower jaw. Scales are small and embedded giving burbot the appearance of being slimy. The anal and dorsal fins run nearly half the length of the body. In Maine, coloration ranges from a tan to dark brown background overlaid with dark brown to black mottling or spots. Some may be uniformly dark brown or black.
Common Name: Rainbow Smelt
Other Names: Smelt, Freshwater Smelt, American Smelt
Identification: Their body is long and slender with a
large elongated, pointed mouth. They have strong conical teeth on jaws and tongue, with fewer than 75 scales along lateral line. Color is silver with a green back, and iridescent purple, pink, and blue reflections on the side. An adipose fin is present.
Common Name: Lake Whitefish
Other Names: Whitefish
Identification: Overall coloration is silvery dark brown to black on the back, becoming silvery on the sides and silvery white below. The fins are generally black or black tipped. Scales are large. The body is somewhat laterally compressed. Lake whitefish are easily distinguished from fallfish (chub) by having a small mouth and the presence of a small adipose fin located on the back between the dorsal and caudal fins. A related species, the round whitefish is light brown on the back becomingsilvery on the side. It has a more cylindrical body shape than the lake whitefish.
Common Name: Round Whitefish
Other Names: Frostfish, Round Fish, Menominee Whitefish
Identification: Round whitefish are noticeably
cylindrical in body shape. They are dark brown on the back fading to silvery sides and silvery-white below. Pectoral and pelvic fins are typically light orange in color. Scales are large. An adipose fin, characteristic of members of the Salmonid family, is located on the backbetween the dorsal and caudal fins. The mouth is small and toothless as adults.
