Colorado designated the greenback cutthroat trout as its official state fish in 1994. While often mistaken for other subspecies of cutthroat trout, the greenback possesses unique characteristics that set it apart. This article delves into the fascinating world of Colorado’s state fish, exploring its history, habitat, and the conservation efforts underway to protect this iconic species.
A History of the Greenback Cutthroat Trout
The greenback cutthroat trout, scientifically known as Oncorhynchus clarkii stomias, is one of fourteen subspecies of cutthroat trout native to the western United States. Named for the distinctive red slashes under its jaw and the emerald green coloration along its back, this fish thrives in cold, clear, high-altitude streams.

Historically, greenback cutthroat trout were found throughout the South Platte River Basin in Colorado and a small portion of Wyoming. However, by the mid-20th century, habitat loss, overfishing, and the introduction of non-native trout species led to a dramatic decline in greenback populations. In fact, the species was thought to be extinct until a small population was rediscovered in 1970 in Bear Creek, a tributary of the Arkansas River.
The Greenback Cutthroat Trout: A Conservation Success Story
The rediscovery of the greenback cutthroat trout sparked a major conservation effort. Biologists with Colorado Parks and Wildlife (CPW) have been instrumental in implementing a multi-faceted recovery plan that includes:
- Habitat Restoration: Restoring degraded streams and riparian areas to create suitable spawning and rearing habitat for the fish.
- Non-Native Species Removal: Working to remove invasive trout species that compete with greenback cutthroat trout for food and resources.
- Stocking Programs: Raising greenback cutthroat trout in hatcheries and stocking them into historically occupied waters to help reestablish populations.
- Genetic Research: Utilizing genetic analysis to ensure the purity of greenback cutthroat trout populations and to inform conservation strategies.

These conservation initiatives have been remarkably successful. Greenback cutthroat trout populations have rebounded, and the species’ status was recently downlisted from “threatened” to “endangered” under the Endangered Species Act. While challenges remain, the recovery of the greenback cutthroat trout stands as a testament to the power of collaborative conservation efforts.
“The greenback cutthroat trout is a resilient species, and its recovery is a testament to the dedication of countless individuals and organizations,” says Dr. LeeAnne McHenry, a fisheries biologist with Colorado Parks and Wildlife. “By working together, we can ensure that this iconic fish continues to thrive in Colorado’s waters for generations to come.”
Identifying the Greenback Cutthroat Trout
Identifying greenback cutthroat trout can be challenging, as they closely resemble other subspecies of cutthroat trout. Here are some key characteristics that distinguish the greenback:
- Red Slash Marks: Prominent red slashes under the jaw, known as “cutthroat” marks.
- Emerald Green Coloration: A distinctive emerald green back and upper sides.
- Black Spots: Numerous, small black spots scattered across the body, extending below the lateral line.
- Habitat: Found exclusively in cold, clear, high-elevation streams within the South Platte River Basin in Colorado and a small portion of Wyoming.

The Future of Colorado’s State Fish
The greenback cutthroat trout is a conservation success story, but its future is not guaranteed. Continued efforts to protect and restore its habitat, mitigate the impacts of climate change, and manage non-native species will be crucial for the long-term survival of this iconic fish.
By understanding the importance of the greenback cutthroat trout and supporting conservation initiatives, we can all play a role in ensuring that Colorado’s state fish continues to grace the state’s waterways for generations to come.
FAQ:
-
Where can I fish for greenback cutthroat trout?
Due to their protected status, angling for greenback cutthroat trout is generally restricted. However, Colorado Parks and Wildlife occasionally stocks certain waters with greenback cutthroat trout for recreational fishing opportunities. Check the current fishing regulations for specific information. -
What do greenback cutthroat trout eat?
Greenback cutthroat trout are opportunistic feeders, consuming a variety of aquatic insects, crustaceans, and small fish. -
How big do greenback cutthroat trout grow?
Greenback cutthroat trout typically reach lengths of 12-18 inches, but some individuals can grow larger in ideal conditions. -
What is being done to protect greenback cutthroat trout from climate change?
Climate change poses a significant threat to cold-water fish species like the greenback cutthroat trout. Conservation efforts are focusing on identifying and protecting climate-resilient habitats, restoring riparian areas to provide shade and cooler water temperatures, and reducing other stressors that may exacerbate the impacts of climate change. -
How can I get involved in greenback cutthroat trout conservation?
Consider supporting organizations involved in greenback cutthroat trout conservation, volunteering your time to assist with habitat restoration projects, and practicing responsible fishing ethics to help protect this important species.
