Two Types of Trout, Two Different Approaches: Fly Fishing for Rainbow and Brown Trout

Fly fishing for rainbow trout and brown trout are two popular and rewarding activities, but there are a few key differences between the two. Understanding these differences can help you choose the right gear, flies, and techniques for success.


One of the main differences between rainbow trout and brown trout is the habitat in which they are typically found. Rainbow trout are usually found in small to medium-sized rivers and streams with clear, cold water. They are often found in areas with a good flow and oxygen content, and they tend to prefer waters with a pH between 6.5 and 7.5.





On the other hand, brown trout are more commonly found in larger rivers, lakes, and ponds. They are less sensitive to water temperature and pH than rainbow trout, and they can be found in a wider range of habitats.


Another difference between these two species is the type of flies that are typically used to catch them. Rainbow trout are often caught using dry flies, which float on the surface of the water. These flies mimic insects such as mayflies and caddisflies, which are a common food source for rainbow trout.


Brown trout, on the other hand, are often caught using nymphs, which are fished beneath the surface. These flies mimic the underwater stages of insects such as mayflies, caddisflies, and stoneflies. Nonetheless, we find that at El Saltamontes Lodge, you can have great success catching both trout with dry flies.


In terms of behavior and feeding habits, rainbow trout tend to be more opportunistic feeders, striking at a wide range of flies. They are also more likely to feed near the surface, making them easier to spot and target.

Brown trout, on the other hand, tend to be more selective and may be more difficult to catch. They are less likely to rise to the surface to feed, and they may require more precise presentations of the fly.


Overall, fly fishing for rainbow trout and brown trout are both enjoyable and challenging activities, but there are some key differences between the two. By understanding the habitat, flies, and behavior of these fish, you can choose the right gear and techniques for success.
