Trout Trek Day One: 14 Days, 14 Species - Rainbow Trout

Last night I was listening to a live Facebook event from Wet Fly Swing, where they were announcing the winners of a fantastic prize package from an event they had been holding throughout the week. I was one of those 400 or so hopefuls, tuned in and eagerly waiting as they carried out their pre-announcement festivities. In typical fashion they talked about gear and various aspects of fishing for about 30 minutes, prior to the grand prize announcement, and they keep the suspense going quite well. I always enjoy their little announcement ritual as they typically introduce a brand of products, or a distributor of said products, that I have not been made privy to, prior to said event, and I always enjoy listening to them discuss different ways I can spend my money. During this event, they will ask various questions that Facebook onlookers can respond to, in hopes of winning bonus prizes. One question that was asked during this event, that I was stumped by, was the question, “How many species of trout are there?” I couldn’t answer fast enough to be the first responder and the winner of a cool new Umpqua chest pack, but as curiosity got the best of me, I went digging and got some useful information out of my research, and I thought I would share with all of you. 

As we all know, fly fishing for trout is a fascinating endeavor, and knowing about the various species and the techniques involved in catching them, can greatly enhance the overall angling experience. If you didn’t know, like me, there are fourteen different species of trout. We aren’t talking about hybrids and weird strains of trout, like the Lahontan Cutthroat found in Pyramid Lake, we are simply talking about actual species of thoroughbred trout. Here is some information I found and thought it would make for a good read, for those, like me, who didn’t know. 

Day one… Rainbow Trout (Oncorhynchus Mykiss)…

Most of the fishing I did growing up, involved Rainbow Trout. Everywhere I moved throughout my adult life, most of what I was catching was Rainbow Trout. They’re everywhere, and if you’re reading this, I am sure the allure of this article is slowly diminishing as the common nature of this fish is not likely to entice most to read it. However, I am always intrigued by the details, so I am writing this anyway. Rainbow trout, scientifically known as Oncorhynchus mykiss, are a favorite among fly fishermen for their striking appearance and spirited fight. These beautiful fish can be found in a variety of habitats across North America, Asia, and Europe, making them a sought-after species for anglers. In today’s blog, we'll explore the fascinating world of Rainbow Trout, from their unique characteristics to effective fly-fishing techniques.

I. Appearance and Characteristics

Rainbow Trout are aptly named for the brilliant colors that adorn their bodies. Here are some key features that make them stand out:

• Coloration: Rainbows display a wide spectrum of colors, ranging from a silvery-blue on their dorsal side to a pinkish-red stripe running along their lateral line. The most striking feature is the vibrant pink or red stripe that gives them their name.
• Size: Rainbow Trout vary in size, but they can grow up to 30 inches or more in length, depending on their habitat and available food sources.
• Fins: They typically have dark spots scattered across their back, dorsal fin, and tail, adding to their distinctive appearance.

II. Habitat and Range

Rainbow Trout are incredibly adaptable and can be found in a range of aquatic environments, including:

• Rivers and Streams: Rainbows are often associated with freshwater rivers and streams, particularly those with clear, cold water. They prefer swift currents and can be found in pools, riffles, and runs.
• Lakes: In addition to moving water, they are also found in lakes and reservoirs, where they adapt well to different depths and water conditions.
• Geographical Range: While native to North America's Pacific Coast, Rainbow Trout have been introduced worldwide. They thrive in various regions, including the Pacific Northwest, the Great Lakes, Europe, and parts of Asia.

III. Feeding Habits

Rainbow Trout are opportunistic feeders, which means they are not particularly selective about their food. Their diet includes:

• Aquatic Insects: They commonly consume mayflies, caddisflies, stoneflies, and other aquatic insects found in their habitat.
• Small Fish: In larger bodies of water, Rainbows may prey on smaller fish like minnows and fry.
• Terrestrial Insects: When available, they will also feed on terrestrial insects that fall into the water.

IV. Fly Fishing Techniques for Rainbow Trout

Now, let's explore some effective fly-fishing techniques for targeting Rainbow Trout:

• Dry Flies: Since Rainbows often rise to the surface to feed on insects, dry flies are a popular choice. Patterns like Elk Hair Caddis, Adams, and Royal Wulff can mimic adult insects on the water's surface.
• Nymphing: Fishing with nymphs (imitations of aquatic insect larvae) is productive, especially in deeper pools. Use patterns like Pheasant Tail, Hare's Ear, or Prince Nymph.
• Streamer Fishing: When Rainbow Trout are in pursuit of larger prey, streamers imitating small fish or leeches can be highly effective. Try Woolly Buggers, Muddler Minnows, or Zonkers.
• Indicator Fishing: Using a strike indicator with nymphs or streamers can help detect subtle takes, especially when Rainbows are holding in deeper water.
• Matching the Hatch: Observe the local insect activity and try to match the prevalent insects in both size and color to increase your success.

V. Conservation and Catch-and-Release

As responsible anglers, it's important to practice catch-and-release when pursuing Rainbow Trout. Many populations are vulnerable, and conservation efforts are crucial to preserving their habitats and genetic diversity.

In conclusion, Rainbow Trout are not only a visually stunning species but also a challenging and rewarding catch for fly fishermen. Whether you're casting your line in a mountain stream or a serene lake, the pursuit of these remarkable fish is sure to provide memorable moments and exhilarating experiences on the water.
