NC Native Trout Species

 |
Rainbow Trout
Oncorhynchus Mykiss
Average Stream Size
Length:10 in. to 16 in. Weight: 2 to 6 lbs.
Rainbow trout are native to the Pacific Ocean and fresh waters of western North
America. They naturally range from Mexico to Alaska and inland to the Rockies.
However, they have been widely introduced throughout the world, and the eastern coast. Rainbow trout were first
introduced to Atlantic Canada in the late 1800s.

Food
Rainbow trout take a wide variety of foods, but in freshwater they eat mainly
insects, crustaceans, snails, leeches, and other fish if available. Alll trout
are opportunistic feeders, which means if a meal, such as a worm or a minnow--or
what is perceived by the trout as a meal. |
Water Habitat
Rainbow trout prefer very similar habitats to brown trout and can
tolerate higher water temperatures. They often use lower reaches of
rivers and streams. |
|
Spawning
They prefer water temperatures of 53 degrees to 64 and do well in clear, cool,
deep lakes or cool, clear, moderately-flowing streams with abundant cover and
deep pools. They spawn in the spring (usually from March to May) in small
tributaries of rivers, or in inlets or outlets of lakes. Spawning can also take
place in late fall or early winter.
Life Expectancy is 6-8 years in the wild. |
Description
In North Carolina, the adults in fresh water colors vary from becoming silvery
on the sides to becoming yellow on the sides and brown on the back.
Many small black spots cover the head, back, sides and fins, and spots on the
tail are in obvious rows. The adipose fin (small fin in front of the tail on the
back) has a black border. Mature fish have a distinctive rosy stripe along the
side that extends from the gill cover to the caudal fin.
Young rainbow trout (parr): have 5 to 13 well-spaced dark part marks on the
sides and show less spotting on the body than adults. |

Brown Trout
Salmo Trutta
Average Stream Size
Length: 8 in. to 14 in. Weight: 2 to 4 lbs.
For centuries before the discovery of rainbows, cutthroats, and brookies, when
people went "trout" fishing, they went brown trout fishing. Native to Europe,
browns were first formally stocked in the United States on April 11, 1884 in
Michigan's Pere Marquette River. Today they can be caught in the Northeast, the
Appalachians, the Upper Midwest, and the mountainous regions of the West.
Life Expectancy is 6-8 years in the wild. |
|
Food
Variety of aquatic and terrestrial insects, earthworms, snails, crayfish,
salamanders, frogs, sculpins, dace, and even their own fry. All trout are
opportunistic feeders, which means if a meal, such as a worm or a minnow--or
what is perceived by the trout as a meal, is usually eaten. Many larger browns
are primarily nocturnal feeders, and during prolific insect hatches, browns can
be extremely selective about what they'll eat |
Water Habitat
Brown trout prefer very similar habitats to our native brook (speckled) trout
except that they can tolerate slightly higher water temperatures. They often use
lower reaches of rivers and streams that are unsuitable for brook trout. |
|
Spawning
Brown trout spawn in the fall and early winter (October to February) at the same
time Brook (speckled) trout spawn, or later.The female uses her body to excavate
a nest (redd) in the gravel. She and the male may spawn there several times. A 5
lb female produces about 3400 golden Coloured eggs that are 4 to 5 mm in
diameter. Females cover their eggs with gravel after spawning and the adults
return downstream. The eggs develop slowly over the winter, hatching in the
spring. A good flow of clean, well-oxygenated water is necessary for successful
egg development.
After hatching, the young fish (called alevins) remain buried in the gravel and
take nourishment from their large yolk-sacs. By the time the yolk-sacs are
absorbed, water temperatures have warmed to 44 degrees to 53 degrees. The fish
(now known as fry) emerge from the gravel and begin taking natural food. They
mature in their third to fifth year and many become repeat spawners. |
Description
In North Carolina, their sides are silvery or brownish yellow and bellies are
white or yellowish; dark spots, sometimes encircled by a pale halo, are
plentiful on the back and sides; spotting also can be found on the head and the
fins along the back; rusty-red spots also occur on the sides; the small adipose
(or fatty) fin in front of the tail has a reddish hue; They closely resemble
Atlantic salmon and rainbow trout, but salmon have no red coloration on the
adipose fin and rainbow trout have lines of black spots on the tail. Young brown
trout (parr) have 9-14 dark narrow parr marks along the sides and some red
spotting along the lateral line. |

Brook Trout
Salvelinus fontinalis
Average Size
Length: 6 in. to 8 in. Weight: 1/4 to 1/2 lbs.
The brook trout is regarded, as one of North America's most beautiful native
fish species. In the Southern Appalachians, locals call them "specks." Recent
genetic studies suggest that the native brook trout found in the Southern
Appalachians, including the mountains of western North Carolina, may be a
separate subspecies of the brook trout found farther north.
Life Expectancy usually short-lived, seldom longer than 4 years in the wild. Maximum 8 years. |
|
Food
Variety of aquatic and terrestrial insects, earthworms, snails, crayfish,
salamanders, frogs and occasionally small fish. Artificial flies in the 12-18
size. |
Spawning
Occurs in fall, generally September through November. Female constructs nest (redd)
in gravel. Adults do not guard nest. Numbers of eggs vary from 100 to 5,000
depending upon the size of female. Incubation period varies depending upon water
temperature. Eggs hatch in 50 days at 50 F. |
|
Water Habitat
Brook trout are most abundant in isolated, high-altitude head- water streams and
brooks where the water is free of pollution and rich in oxygen. Brook trout are
inherently cold-water fish, and can perform well within a temperature range of
40 to 68 degrees Fahrenheit. However, brook trout have been shown to feed at
temperatures as low as 34 degrees, and the lethal temperature limit of the brook
seems to be around 30 degrees. Brook trout prefer streams with stable water
flows, silt-free gravel for spawning and an abundance of deep pools and riffles
with sufficient in-stream cover, such as logs, boulders and undercut banks. In
North Carolina, brook trout spawning begins in September and continues through
November. The fertilized eggs are covered with gravel and remain in the redd
until they hatch in the early spring (usually March) |
Description
In North Carolina, brook trout are generally small, ranging in size up to about
8 inch seldom more than 12 inches. They are handsomely colored with the back and
upper sides of the body typically olive-green with mottled, dark green wavy
markings that extend onto the dorsal and caudal fins. The lower sides are
lighter with yellow spots interspersed with fewer spots of bright red surrounded
by blue.
Easy Identification
The lower fins are orange with a narrow black band next to a
white band that borders the forward edge. Spawning fish acquire a heightened
brilliance when the belly and lower fins become a bright red-orange. The color
of a fish can vary from one area to another, depending upon the surrounding
habitat. |
