Idaho State Fish
Cutthroat Trout
(Salmo clarki)
formerly
(Oncorhynchus clarki)
Adopted on April 5, 1990.
In 1990, a class of Mr. Killet's fourth grade kids from a small Idaho town had an idea and took it to the legislature. As a result, the Cutthroat Trout was designated the Idaho fish by the 42nd Idaho Legislature and approved by Governor Cecil Andrus on April 5, 1990. The Cutthroat, along with the Rainbow and Bull Trout, is native to Idaho. The scientific name for Cutthroat Trout, (Oncorhynchus clarki,) is in reference to William Clark who first described in detail the Cutthroats of the Columbia River. His partner Meriwether Lewis earlier encountered Cutthroats near the great falls of Montana's Missouri River in July of 1805. Cutthroat species found in Idaho are the West slope Cutthroat which is found in northern and central Idaho and the Yellowstone Cutthroat which is found in southeastern Idaho.
Idaho cutthroat trout are usually caught on artificial flies, small spoons and small spinners.
While Montana, Idaho and Wyoming simply adopted the "cutthroat trout" as their fish, Colorado, Utah, Nevada, and New Mexico adopted particular subspecies of fish.
Idaho State Fish: Cutthroat Trout
The body color varies with the back ranging from steel gray to olive green. The sides may be yellow brown with red or pink along the belly. The Cutthroat name comes from the distinctive red to orange slash on the underside of its lower jaw.
All cutthroat trout have a "cut," a patch of orange or red on the throat and they differ from the rainbow trout because they have basibranchial (hyoid) teeth in their throat between the gill arches, they typically have longer heads and jaws than the rainbow and often times can be distinguished from the rainbow by their larger spots. The cutthroat is known to be more vulnerable to anglers because of a general lack of wariness and can be caught on a wide variety of bait.

AN ACT, RELATING TO THE DESIGNATION OF A STATE FISH; PROVIDING LEGISLATIVE INTENT; AMENDING CHAPTER 45, TITLE 67, IDAHO CODE, BY THE ADDITION OF A
NEW SECTION 67 4508, IDAHO CODE, TO DESIGNATE THE CUTTHROAT TROUT AS THE STATE FISH.
Be It Enacted by the Legislature of the State of Idaho:
SECTION 1. It is the sense of the legislature that the Cutthroat trout is the fish best representing all Idaho waters and anglers. The Cutthroat trout's
historic significance as the first of the salmon or trout in Idaho and as a key resource for early Idahoans makes this fish an important part of Idaho's
natural heritage. This fish's sensitivity to changing and degraded environments and its value as a sport fish for Idaho anglers makes it an ideal barometer
for the quality of life. Dramatic declines in recent history highlight problems in natural environments and resource management. Recognition as the
state fish can help build the public awareness and support necessary for thoughtful use of our aquatic habitats and all associated resources. Cutthroat
trout can be a symbol of Idaho's natural heritage and high quality environment.
SECTION 2. That Chapter 45, Title 67, Idaho Code, be, and the same is hereby amended by the addition thereto of a NEW SECTION, to be known and designated
as Section 67 4508, Idaho Code, and to read as follows:

Approved April 5, 1990.
