Blue
Catfish have a forked tail and are very similar to the channel catfish.
However, unlike other catfish, they prefer clean rivers with a fairly
swift current flow. Blue catfish normally weigh about 20 to 40 pounds,
but have been reported as large as 350 pounds! They can be found throughout
the Mississippi River system. |
| Channel
Catfish are the sleeker, more attractive version of the catfish. They
are silvery gray to coppery brown with a white belly. Younger fish
have small black spots that fade as they become adults. They have
a deeply forked tail fin. |

The
Cutthroat Trout was first seen by Meriwether Lewis on the journey
westward, however, William Clark wrote the first detailed description
of the fish. Because of this, Clark is referenced in the trout's scientific
name, Oncorhynchus clarki. The "cutthroat" part of
its common name comes from the red- to orange-colored slash on the
underside of its lower jaw. The Cutthroat gets up to 18 inches long
and lives about 7 years. |
| The
Sauger fish looks very much like its brother the walleye, however
it is smaller and exists in fewer numbers. You can tell the two apart
by looking closely at the dorsal fin;
the Sauger has a row of dark spots there. This fish usually only gets
as large as two to three pounds, but it has a large mouth with many
sharp teeth. Its common names are sand pike, ground pike, and spotfin
pike. The Sauger is not a pike, however,
it is actually a type of perch. |

The
Goldeye fish varies from dark blue, blue-green on the back with the
sides silvery and the belly white. They feed at night and eating a
diet of insects, crustaceans, mollusks, fish, frogs and small animals
(they are opportunistic foragers, eating nearly any organism
they encounter). Goldeye are about 12 inches long when they are full-grown. |
| White
Sturgeon are the largest freshwater fish in North America and can
weigh over 1,500 pounds, and be 20 feet in length. They live in the
deep pools of large rivers and over soft bottoms in the ocean. White
Sturgeons are on the U.S. Endangered Species List. They are highly
valued commercially for their caviar and meat, and also as a sport
fish. |

The
Eulachon (Thaleichtys pacificus) is a type of smelt. It is
known as the "candlefish" because of its traditional use
as a candle when dried and fitted with a wick. The genus name, Thaleichtys,
is Greek for "rich fish" and refers to the high oil content
of the Eulachon's flesh. They are small fish, up to 10 inches in length,
and are blue-silver in color. |
| The
Starry Flounder was first noted by the Expedition in March, 1806,
at Fort Clatsop, Oregon. They have eyes on either their left or right
side (not both). The eyed side is dark brown to black with blotches,
and the blind side is white to creamy white and sometimes blotched.
Starry Flounder are found throughout the eastern Pacific ocean. They
feed on crabs, shrimps, worms, clams, and small fishes. |

The
marine version of this fish is known as Steelhead Trout and is metallic-blue
in color above, silvery-white below, with small, black spots on the
back, sides, and fins. The freshwater version, Rainbow Trout, have
bigger spots and red bands on the sides. They are found from the Bering
Sea to southern California. Steelhead Trout are on the Endangered
Species List. |
| The
Columbia River Chub was first noted by the Expedition on April 26,
1806, in the Columbia River, below the mouth of the Umatilla River,
Washington. |

The
Northern Squawfish (Northern Pikeminnow) is a slender, pikelike fish,
grayish-green in color. Spending its life in lakes, pools, and rivers
of the Snake and Columbia River Basins of north, central, and southwest
Idaho and northwest Montana, and in the Puget Sound rivers, and the
Lake Washington, Columbia, Snake, and Willamette tributaries. |
| Mountain
Suckers are bottom-dwelling, freshwater fish, normally no larger than
8 inches in length. They usually prefer cool, clear streams with clean
rubble or sand bottoms, but are sometimes found in lakes. Mountain
Suckers rely almost entirely on algae for food. They were found by
Lewis and Clark just east of present-day Livingston, Park County,
Montana, in July 1806. |
