Trout fishing is a beloved pastime for anglers across the globe, and two of the most popular species are the cutthroat trout and the rainbow trout. While they share similarities in appearance and habitat, these two fish have distinct characteristics that set them apart. This article will delve into the key differences between cutthroat and rainbow trout, helping you become a more knowledgeable angler and appreciate the unique qualities of each species.

Appearance:

• Cutthroat Trout: True to their name, cutthroat trout are easily identified by the bright red slash beneath their lower jaw, which resembles a "cutthroat." They typically have a dark olive-green to brownish back, with silvery-white sides and spots that are often black-edged.
• Rainbow Trout: As their name suggests, rainbow trout boast a beautiful iridescent band that runs along their sides, showcasing a spectrum of colors. They have a darker back, ranging from olive green to dark brown, and their sides are typically silvery-white with black spots.

Distribution:

• Cutthroat Trout: Native to western North America, cutthroat trout are found in rivers and lakes from Alaska to Mexico. They are especially prevalent in the Rocky Mountains and the Pacific Northwest.
• Rainbow Trout: Originating in the Pacific Ocean, rainbow trout have been introduced to various regions worldwide, including Europe, Asia, and Australia. They can adapt to a wide range of habitats, making them a popular species for stocking lakes and reservoirs.

Behavior and Diet:

• Cutthroat Trout: Cutthroat trout are known for their aggressive nature and territoriality. They primarily feed on aquatic insects, crustaceans, and smaller fish.
• Rainbow Trout: Rainbow trout are generally more opportunistic feeders, consuming a wider variety of prey, including insects, amphibians, and even small mammals. They can be more aggressive towards larger prey than cutthroat trout.

Fishing Techniques:

• Cutthroat Trout: Cutthroat trout are often caught using fly fishing techniques, with dry flies and nymphs being effective choices. They also respond well to bait fishing using worms, salmon eggs, or spinners.
• Rainbow Trout: Rainbow trout are versatile feeders and can be caught using various methods. Fly fishing, bait fishing, and spinning lures are all popular choices.
