The Official Idaho State Fish

Cutthroat trout (Oncorhynchus clarkii)

Oncorhynchus clarkii, commonly known as the Cutthroat trout, is a fascinating species that has been designated as the official state fish of Idaho. This type of trout is native to the western United States, including Idaho, and can be found in various rivers, streams, and lakes throughout the state. The Cutthroat trout is easily recognizable due to its distinctive red or orange slash marks on the underside of its jaw, giving it its name. It is also known for its bright, vibrant coloration, ranging from olive green to silver, with speckles of red, orange, and yellow along its sides.

One interesting fact about the Cutthroat trout is its unique life cycle. They are anadromous, meaning they are born in freshwater, migrate to the ocean, and then return to freshwater to spawn. This migration can cover hundreds of miles, making them a resilient and adaptable species. Cutthroat trout are also known for their aggressive feeding habits, making them a popular game fish among anglers. They primarily feed on insects, crustaceans, and small fish, using their sharp teeth to catch their prey.

The Cutthroat trout was designated as the official state fish of Idaho in 1990. This decision was made due to the species' historical and cultural significance in the state. The Cutthroat trout has been an important food source for Native American tribes in Idaho for centuries, and it continues to be a vital part of the state's economy through recreational fishing. Additionally, the Cutthroat trout is a symbol of the state's pristine rivers and lakes, highlighting the importance of conservation efforts to preserve these natural habitats.

In conclusion, Oncorhynchus clarkii, or the Cutthroat trout, is a unique and important species that has earned its place as the official state fish of Idaho. Its distinctive appearance, life cycle, and cultural significance make it a fascinating creature to learn about and admire. As the Idaho state fish, it serves as a reminder of the state's natural beauty and the importance of protecting and preserving its diverse wildlife.
